As the Braves open camp, they'll provide a glimpse of how much they have progressed since claiming an unexpected division crown last year. Freddie Freeman, Ronald Acuna Jr. and Ozzie Albies will once again be in a lineup that has been enriched by the addition of Josh Donaldson, the former American League MVP Award winner who thus far arguably ranks as baseball's top free-agent signee.

Freddie Freeman spent the offseason sharing excitement about the possibility that Josh Donaldson would not end up being the Braves' only significant offseason addition.

On this opening week of Spring Training, all 30 Major League teams have one thing in common: optimism. Here's an optimism cheat sheet for each of them.

As Braves manager Brian Snitker evaluates who might serve as his closer, A.J. Minter has made it clear he wants to be the guy who is consistently called upon to handle high-leverage threats that develop in late innings.

While playing close to his Alabama home and enjoying a chance to once again work with Atlanta general manager Alex Anthopoulos, the former American League MVP Award winner Josh Donaldson also understands the importance of rejuvenating his career with his deal.

The next five weeks will see lots of shuffling on Major League rosters. Here are the most intriguing positional battles on each of the 30 MLB clubs.

Having seen what Luiz Gohara had done upon his introduction to the big leagues the previous September, Freddie Freeman told Alex Anthopoulos the big left-hander might immediately became an All-Star. Instead, it became a year of awakening for the young hurler, who remains fueled by last year's disappointments.

Sean Newcomb entered last June as an All-Star candidate and exited the regular season wondering if he had done enough to earn a spot on Atlanta's postseason roster. The inconsistent nature of his first full Major League season enhances the difficulty of projecting how valuable he might be to the Braves from both an immediate and long-term perspective.

To those of a certain age, Frank Robinson was the definition of greatness, leadership and toughness. Well into his 70's and 80's, he carried himself with the confidence and unmistakable gait of a great athlete.

In outlining their plans to rebuild the Orioles following the least successful season in franchise history, new club officials routinely point to experience: They just did the same thing elsewhere.

Frank Robinson, a trailblazing figure who was Major League Baseball's first African-American manager and one of its greatest players during a career that spanned 21 seasons, died Thursday after a prolonged illness. He was 83.

All 30 Major League teams will wear special "MLB 150" patches on their uniforms for the entire 2019 season in honor of the 150th anniversary of the 1869 Cincinnati Red Stockings, the first openly all-salaried professional baseball team.

Fans and analysts spend the entire offseason speculating where the top free agents could go, but sometimes an under-the-radar pickup can end up making a world of difference. As positional competitions begin to heat up at Spring Training camps this month, MLB.com's beat writers were asked to identify one potentially overlooked acquisition for each of the 30 clubs. Here's who they came up with.

A year ago, Danny Farquhar was not going to be in the middle of a spring storyline. That's going to change this spring as he tries to win a spot in the Yankees' bullpen

As we inch closer and closer to Opening Day, we'll continue to take a position-by-position look at the Orioles roster options and remaining questions. Now that pitchers and catchers have officially reported to Spring Training, now feels like a good time to take a look behind the plate, where the Orioles have a ton of options but no clear answer.

Wave him bye bye. A legendary voice of Orioles baseball is calling it a career. Joe Angel, beloved play-by-plan man and voice of the Orioles' radio broadcasts for nearly two decades, announced his retirement this week. The decision caps a 41-year career in the booth for Angel, 71, a fixture for 19 seasons across two stints in Baltimore.

Looking to preempt questions about his work ethic in a nightmare 2018 season, Chris Davis reported to Spring Training in Florida more than a week before Orioles position players were required to. That's when his efforts to rebound hit their first minor snag.

The Orioles' cloudy infield picture gained some clarity Saturday when the team signed veteran shortstop Alcides Escobar to a Minor League contract with an invitation to Spring Training.

A lot has to go right for Yusniel Diaz to crack the Orioles' Opening Day roster. But the Orioles' No.1 prospect per MLB Pipeline isn't letting that impede his plans to compete for a spot anyway.

The next five weeks will see lots of shuffling on Major League rosters. Here are the most intriguing positional battles on each of the 30 MLB clubs.

Orioles right-hander Hunter Harvey had hopped off a backfield mound at the club's Spring Training complex and exhaled. He was one of 14 pitchers scheduled to face hitters as part of the club's first full-squad workout on Monday, and now that he had, Harvey was asked to recall when was the last time he threw competitive pitches.

Taking reps behind Chris Davis at first base, Orioles prospect Ryan Mountcastle became the most high-profile participant yet in the club's grand spring experiment.

The Orioles will honor late icon Frank Robinson during Grapefruit League play and will continue to do so throughout the season, with a patch on the sleeves of their uniforms. The patch features Robinson's No. 20 in orange against a black background.

The ability to switch fuels for oxidation in response to changes in macronutrient composition of diet (metabolic flexibility) may be informative of individuals’ susceptibility to weight gain. Seventy-nine healthy, weight-stable participants underwent 24-h assessments of energy expenditure and respiratory quotient (RQ) in a whole-room calorimeter during energy balance (EBL) (50% carbohydrate, 30% fat) and then during 24-h fasting and three 200% overfeeding diets in a crossover design. Metabolic flexibility was defined as the change in 24-h RQ from EBL during fasting and standard overfeeding (STOF) (50% carbohydrate, 30% fat), high-fat overfeeding (HFOF) (60% fat, 20% carbohydrate), and high-carbohydrate overfeeding (HCOF) (75% carbohydrate, 5% fat) diets. Free-living weight change was assessed after 6 and 12 months. Compared with EBL, RQ decreased on average by 9% during fasting and by 4% during HFOF but increased by 4% during STOF and by 8% during HCOF. A smaller decrease in RQ, reflecting a smaller increase in lipid oxidation rate, during HFOF but not during the other diets predicted greater weight gain at both 6 and 12 months. An impaired metabolic flexibility to acute HFOF can identify individuals prone to weight gain, indicating that an individual’s capacity to oxidize dietary fat is a metabolic determinant of weight change.

The whitening and loss of brown adipose tissue (BAT) during obesity and aging promote metabolic disorders and related diseases. The imbalance of Ca²⁺ homeostasis accounts for the dysfunction and clearance of mitochondria during BAT whitening. Capsaicin, a dietary factor activating TRPV1, can inhibit obesity induced by high-fat diet (HFD), but whether capsaicin inhibits BAT loss and the underlying mechanism remain unclear. In this study, we determined that the inhibitory effects of capsaicin on HFD-induced obesity and BAT whitening were dependent on the participation of SIRT3, a critical mitochondrial deacetylase. SIRT3 also mediated all of the beneficial effects of capsaicin on alleviating reactive oxygen species generation, elevating mitochondrial activity, and restricting mitochondrial calcium overload induced by HFD. Mechanistically, SIRT3 inhibits mitochondrial calcium uniporter (MCU)-mediated mitochondrial calcium overload by reducing the H3K27ac level on the MCU promoter in an AMPK-dependent manner. In addition, HFD also inhibits AMPK activity to reduce SIRT3 expression, which could be reversed by capsaicin. Capsaicin intervention also inhibited aging-induced BAT whitening through this mechanism. In conclusion, this study emphasizes a critical role of the AMPK/SIRT3 pathway in the maintenance of BAT morphology and function and suggests that intervention in this pathway may be an effective target for preventing obesity- or age-related metabolic diseases.

Adipose tissue macrophages (ATMs) are involved in the development of insulin resistance in obesity. We have recently shown that myeloid cell–specific reduction of HMG-CoA reductase (Hmgcr^m–/m–), which is the rate-limiting enzyme in cholesterol biosynthesis, protects against atherosclerosis by inhibiting macrophage migration in mice. We hypothesized that ATMs are harder to accumulate in Hmgcr^m–/m– mice than in control Hmgcr^fl/fl mice in the setting of obesity. To test this hypothesis, we fed Hmgcr^m–/m– and Hmgcr^fl/fl mice a high-fat diet (HFD) for 24 weeks and compared plasma glucose metabolism as well as insulin signaling and histology between the two groups. Myeloid cell–specific reduction of Hmgcr improved glucose tolerance and insulin sensitivity without altering body weight in the HFD-induced obese mice. The improvement was due to a decrease in the number of ATMs. The ATMs were reduced by decreased recruitment of macrophages as a result of their impaired chemotactic activity. These changes were associated with decreased expression of proinflammatory cytokines in adipose tissues. Myeloid cell–specific reduction of Hmgcr also attenuated hepatic steatosis. In conclusion, reducing myeloid HMGCR may be a promising strategy to improve insulin resistance and hepatic steatosis in obesity.

The signing of veteran outfielder Michael Brantley by the Astros came a week after the Winter Meetings and only a few days before Christmas, meaning it didn't exactly garner much attention on national, or even local, news cycles. For the Astros, Brantley was exactly the player they needed at exactly the right price -- two years and $32 million -- and the kind of addition that should fire up the fanbase.

Fans and analysts spend the entire offseason speculating where the top free agents could go, but sometimes an under-the-radar pickup can end up making a world of difference.

With this many stars and this much talent, you can't help but have visions of playing baseball deep into October. And considering it was only a year ago the Astros were talking about defending their World Series title, their window to win another one remains wide open.

All-Star right-hander Gerrit Cole won his arbitration case against the Astros on Wednesday, meaning he will make $13.5 million this season. The team offerred $11.425 million, a difference of $2,075,000.

The Astros logo outside the Ballpark of the Palm Beaches really is something to see, all the way from Haverhill Rd. The closer you get the bigger it gets, the white "H" right there in front of the huge orange star. Underneath the "H" is the following message, white against orange: "2017 World Champions." It would have been a simple matter to put "2018" down there, too. There was room.

By winning his arbitration case against the Astros, pitcher Gerrit Cole stands to make $2,075,000 more this season than if he'd lost. That's a significant victory for Cole, who will double his salary this year and make $13.5 million, and a significant victory for other players to come, the veteran pitcher said.

With Dallas Keuchel and Charlie Morton leaving in free agency and Lance McCullers Jr. on the mend following Tommy John surgery, Collin McHugh is returning to his roots this year and is back in the Houston rotation. He said his experience as a reliever will only help him evolve as a starter.

All eyes were on right-hander Forrest Whitley, MLB Pipeline's top pitching prospect, when he threw in the bullpen for the first time Friday in Major League camp. Astros manager AJ Hinch, assistant general manager Brandon Taubman and director of player development Pete Putila were all watching intently as Whitley threw 21 pitches -- fastballs, changeups and cutters.

Gerrit Cole and Justin Verlander are not fans of the "opener" and explained why it's not a long-term option.

You can't help but learn a few things when you had the kind of year Astros star shortstop Carlos Correa experienced last season, when a nagging back injury derailed him in the second half and forced him to deal with the biggest adversity of his career.

Astros third baseman Alex Bregman continues to progress from the arthroscopic elbow surgery he had a month to remove bone chips.

The question would come shortly after Cy Sneed would write his name on the chalkboard. A young hand would rise into the air, and Sneed would brace himself for the chuckles that were sure to soon fill the classroom. "Are you a lumberjack?"

The next five weeks will see lots of shuffling on Major League rosters. Here are the most intriguing positional battles on each of the 30 MLB clubs.

The first Hall of Famer to join the Astros at Spring Training is Craig Biggio, who was in uniform for morning workouts on Tuesday and will remain with the team throughout the week.

It took only two words for Alex Bregman to send 9-year-old Jax Nystrom into a frenzy, but this kind of reaction -- young people freaking out at the slightest bit of attention from him -- has become commonplace for the Astros' All-Star third baseman.
