Houck (elbow) began a throwing program Monday with 25 throws from 45 feet, Ian Browne of MLB.com reports.

It's the first time he's thrown a baseball since he underwent a UCL reconstruction and flexor tendon repair six months ago. Houck will continue a deliberate rehab process over the next several months and hopes to make a late-season return, but it's likely the Red Sox will hold him back until 2027.

Reds manager Terry Francona said Sunday that Callihan (forearm) has been fully cleared for all baseball activities during spring training, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Callihan has had an incredibly unlucky professional career when it comes to his health, with his latest setback coming in May, when he snapped his forearm trying to make a sliding catch in Atlanta. He's facing an uphill battle to make the team as a bench player coming out of spring training, with Will Benson and JJ Bleday seemingly ahead of him in the pecking order among Cincinnati's left-handed-hitting corner outfielders.

Suarez is taking reps at first base to start each day of spring training, Charlie Goldsmith of The Dayton Daily News reports. "I'm a guy who likes work," Suarez said. "I want to be better at first base. I know they're going to need me there."

Suarez is still likely to get most of his starts as the Reds' designated hitter, with Ke'Bryan Hayes starting at third base and either Sal Stewart or Spencer Steer playing first base, but every bit of flexibility helps. Suarez played the first three games at first base of his major league career last season.

Halvorsen (elbow) tossed a live batting practice session Monday.

Halvorsen looks to be free of restrictions in the opening weeks of spring training after he didn't pitch after Aug. 2 last season due to a mild right elbow flexor strain. Prior to getting injured, Halvorsen had seemingly established himself as the Rockies' preferred closer, though his numbers (4.99 ERA, 1.56 WHIP, 36:21 K:BB, 11 saves in 14 chances over 39.2 innings) weren't overly remarkable. Even so, Halvorsen still looks like one of the best bets for saves in Colorado entering 2026, given his raw abilities along with the lack of reliable alternatives in the Rockies bullpen. Halvorsen ranked third in the majors last season with an average fastball velocity of 100.0 miles per hour, and his 13.1 percent swinging-strike rate and 54.4 percent groundball rate offer hope that he'll be able to raise his strikeout rate and improve his ERA and WHIP.

Glasnow (side) completed his first live batting practice session of spring training Monday, Bill Plunkett of The Orange County Register reports.

Glasnow dealt with a sore side while making appearances out of the bullpen in the final two games of the Dodgers' World Series victory over the Blue Jays, but the right-hander appears to have had a normal offseason before he reported to spring training last week. Though sustained health has been a rarity for Glasnow during his career, he at least appears to be heading into this spring in a better spot than last year, when he was coming back from an elbow sprain that brought an early end to his 2024 season. Glasnow didn't experience any elbow-related problems during the 2025 regular season but was sidelined for over two months due to shoulder inflammation and also missed a start in August due to back tightness. He remained effective when available, however, finishing with a 3.19 ERA, 1.10 WHIP and 106:43 K:BB over 90.1 innings.

Wong (hand) took part in live batting practice Monday, Ian Browne of MLB.com reports.

Wong reported to camp last week and appears to be fully healthy after he underwent a carpal boss excision procedure on his right hand back on Oct. 9. The hand issue perhaps played a factor in Wong's dramatic drop in production in 2025, when his OPS fell to .500 over his 188 plate appearances after he had posted a .758 OPS the season prior. Carlos Narvaez ended up overtaking Wong on the depth chart, and manager Alex Cora relayed Saturday that Narvaez "earned the right" to be the team's starter heading into 2026, per Gabrielle Starr of the Boston Herald. Cora added that Wong's solid defense behind the plate should allow him to play more frequently than the typical backup catcher, and the 29-year-old could also be an option to make starts first base when Willson Contreras needs a day off.

Manaea worked with Tread Athletics this offseason and believes he's rediscovered his ideal arm slot, Will Sammon of The Athletic reports.

Manaea experienced a breakthrough in 2024 with a lowered arm slot, but he struggled in 2025 after lowering his arm slot even further. He's now got it back closer to where it was in 2024 and said it's "definitely cleaned up and feels a lot better now." The left-hander dealt with a loose body in his elbow last season and didn't have surgery, so the possibility exists that the issue will resurface in 2026. However, Manaea is fully healthy right now and feels good about where he is early on in Mets camp.

Lopez (elbow) completed a bullpen session Monday, Martin Gallegos of MLB.com reports.

Lopez missed the final month and change of the 2025 season due to a left elbow flexor strain, but he appears to have had a normal offseason and doesn't seem to be facing any restrictions in the early stages of camp. The 27-year-old lefty should be guaranteed a rotation spot heading into 2026 after he was one of the few bright spots for a wretched Athletics pitching staff last season with a 4.08 ERA, 1.27 WHIP and 19.0 K-BB% over 92.2 innings.

Weathers touched 98.5 miles per hour with his four-seamer during a live batting practice session Sunday, Brendan Kuty of The Athletic reports.

Weathers averaged 96.9 mph with his four-seamer last season with the Marlins, but it's still a bit of a surprise that he's showing so much velocity this early in spring training. Acquired via trade in January, Weathers has been injury-prone in his career and has been using a foam roller in order to reduce lower-body tightness. The southpaw is expected to open the season in the Yankees rotation while Gerrit Cole (elbow) and Carlos Rodon (elbow) recover from injuries.

Lewis worked with a personal hitting coach, Jeremy Isenhower, this offseason on simplifying his pre-pitch mechanics, Matthew Leach of MLB.com reports.

Isenhower was recommended to Lewis by Bobby Witt and former teammate Jorge Polanco, and Lewis made six different trips to Houston this offseason in order to work with Isenhower. The hope is that, by quieting his pre-pitch movement, Lewis should be able to improve his pitch recognition, swing decisions and quality of contact. After slashing .307/.364/.549 over 70 games in his first two major-league seasons, Lewis has hit a disappointing .235/.288/.416 in 188 contests since the start of the 2024 campaign. He'll be Minnesota's everyday third baseman again in 2026.
