The Marlins announced that Mazur will undergo surgery Wednesday on his right elbow and will miss the entire 2026 season, Christina De Nicola of MLB.com reports.

The report doesn't provide any specifics regarding Mazur's procedure, but the right-hander is presumably ticketed for Tommy John surgery or UCL repair with an internal brace. The latter procedure would give Mazur a chance at avoiding missed time to begin the 2027 campaign, while the right-hander would almost certainly open next season on the injured list if Tommy John surgery is deemed necessary. Even before experiencing discomfort in his elbow last week and getting shut down from throwing, Mazur was facing an uphill battle to make the Marlins' Opening Day rotation and was likely to begin the season at Triple-A Jacksonville. In any event, the loss of Mazur will thin the Marlins' organizational rotation depth.

Griffin was included in the Pirates' projected Opening Day roster by Colin Beazley and Noah Hiles of the Pittsburgh Post-Gazette.

Neither writer cited team sources, so this is far from confirmation that Griffin is breaking camp with the team. However, it is notable that Hiles indicated that the Pirates are trying to win in 2026 and that Griffin has been the team's best shortstop this spring -- a combination that could cause the team to break from their typical conservative nature with prospects. Griffin is just 5-for-24 in Grapefruit League games, but he has recorded four barrels on 18 batted-ball events.

Horton was tagged for six runs on six hits and two walks across 3.2 innings in Tuesday's Cactus League contest against the Rangers. He struck out two.

Horton served up three home runs in a rough spring training outing facing many Texas regulars. He was much better in his spring debut when he tossed two scoreless innings, but that also came nearly two weeks ago, so perhaps there was some rust for the young righty. Horton will look to get back on track and finish Cactus League play on a better note, though his rotation spot should be secure after a stellar rookie campaign in which he recorded a 2.67 ERA, 1.08 WHIP and 97 strikeouts across 118 regular-season innings. Another step forward for Horton in 2026 could make the 24-year-old a fantasy ace.

Shaw went 1-for-3 with a solo home run in Tuesday's Cactus League contest against the Rangers.

The home run was the first of the spring for Shaw, who is batting .310 with an .812 OPS across 11 Cactus League contests. Also notable Tuesday was seeing the youngster start in center field. With Alex Bregman now in the fold to play third base, Shaw is getting comfortable in the outfield, and the Cubs plan to start him regularly in right field against left-handed pitchers. Shaw struggled with consistency during his 2025 rookie campaign, though he still managed 13 home runs and 17 stolen bases. It remains to be seen how much the 24-year-old will play in 2026, but he could take a step forward from a fantasy perspective if he sees the field often enough from a utility role.

Lindor (hand) played four innings at shortstop during a minor-league spring game Tuesday, though he did not hit in the contest, Anthony DiComo of MLB.com reports.

The 32-year-old clearly still has some limitations in his rehab program, but returning to game action, even in a limited capacity, is significant progress in his return from right hamate bone surgery. Lindor said that he's "100 percent optimistic" that he will be available for Opening Day, which is less than three weeks away.

Anthony suffered a fractured toe after fouling a ball off his foot during Monday's Grapefruit League game versus the Red Sox, Lochlahn March of The Philadelphia Inquirer reports.

Anthony is expected to undergo surgery later this week to repair the damage, and a timetable for his return could be revealed following the operation. Once healthy, Anthony is likely to be assigned to Triple-A Lehigh Valley.

Phillies manager Rob Thomson said Tuesday that Lazar is dealing with a "mild" oblique injury and is returning to big-league camp to be evaluated, Jayson Stark of The Athletic reports.

The right-hander suffered the injury during the World Baseball Classic, and his availability for the start of the regular season is now in question. Lazar made 36 regular-season appearances for the Phillies last year and had a 4.79 ERA, 1.28 WHIP and 26:12 K:BB over 41.1 innings.

McDonald has allowed two hits and a walk while striking out seven across six scoreless innings in three Cactus League appearances, and he is making a strong case to open the 2026 campaign in the Giants' bullpen, Maria Guardado of MLB.com reports.

McDonald was recalled from Triple-A Sacramento in September of last season, recording a 1.80 ERA, 1.00 WHIP and 14:2 K:BB across 15 innings in three big-league appearances, including two starts. The right-hander has impressed this spring, and while there isn't expected to be room for him in the starting rotation just yet, he has a good chance to open the season in the bullpen. If injuries arise among San Francisco's starters during the season, the 25-year-old would be a candidate to move into the rotation.

Kelly (back) will make his Cactus League debut Friday against the Royals, Alex Weiner of ArizonaSports.com reports.

Kelly has been behind schedule after coming down with mid-back tightness in late February. The Diamondbacks have already ruled the right-hander out for Opening Day, but Kelly has a good chance to avoid the injured list and make a start in the second series of the season.

Carroll (hand) will make his Cactus League debut as the Diamondbacks' designated hitter in Wednesday's game versus the Athletics, Alex Weiner of ArizonaSports.com reports.

Carroll is less than a month removed from surgery to remove a fractured right hamate bone, but he was cleared to resume swinging a bat by early March and has continued to ramp up his hitting progression without issue. The 25-year-old is being eased back in at DH but should be ready to play the outfield soon. Carroll is on track to be available for Opening Day.
