Kolek felt tightness in his left side while warming up in the bullpen during the Royals' 8-8 tie against the Mariners in Wednesday's Cactus League game, Anne Rogers of MLB.com reports.

Kolek went into the clubhouse to have his left side evaluated by medical staff, and an update on his status should be made Thursday. The 28-year-old right-hander was acquired by the Royals from the Padres at the trade deadline in late July and is competing for a spot in Kansas City's rotation for the 2026 season. Across five starts with the Royals in 2025, Kolek posted a 1-2 record with a 1.91 ERA, 0.76 WHIP and 21:5 K:BB across 33 innings.

Barlow allowed two runs on three hits and no walks across one inning in Tuesday's Cactus League loss to the Brewers. He did not record a strikeout.

Barlow entered in the fifth inning to make his Athletics debut after signing a one-year deal with the club Feb. 6, and he allowed some hard contact, including a pair of two-out doubles by Tyler Black and David Hamilton that each drove in a run. The veteran right-hander is coming off a 2025 campaign in which he posted a 4.21 ERA and 1.39 WHIP with a 9.9 K/9 and a career-worst 5.9 BB/9 across 68.1 innings with the Reds. His 59 career saves will keep him in the mix for closing duties, though middling results in recent seasons offer little security as Barlow competes with fellow veteran Mark Leiter and younger options Justin Sterner, Elvis Alvarado and several other arms.

Latz allowed two hits over two scoreless innings in Tuesday's spring start against Arizona.

Latz made his Cactus League debut and was all over the strike zone, landing 20 of his 26 pitches for strikes. The left-hander delivered first-pitch strikes to six of the eight batters he faced. He's competing with Kumar Rocker for the fifth spot in the rotation, but he could ultimately land in a hybrid role.

Helsley allowed one hit in a scoreless third inning during Tuesday's Grapefruit League game against the Twins.

After signing a two-year, $28 million contract with the Orioles in November, Helsley pounded the zone for 10 strikes among his 12 pitches in his spring debut. The 31-year-old right-hander's fastball velocity topped out at 97.7 mph, and he'll likely be looking to increase that as spring training progresses. With Felix Bautista (shoulder) likely to miss 2026, Helsley is gearing up to function as Baltimore's closer to begin the season.

White signed a minor-league contract with the Mariners on Saturday.

White struggled to find his footing in the minors last year, posting a 7.24 ERA and 1.90 WHIP across 32.1 innings with Detroit's Triple-A affiliate before being released by the club in July. He'll get a chance to redeem himself with the Mariners, though he will most likely be used as bullpen depth at Triple-A Tacoma.

Merryweather was removed from Tuesday's Grapefruit League appearance against the Rays with a left hamstring strain, Bobby Nightengale of the Minneapolis Star-Tribune reports.

Merryweather walked the first batter he saw in the third inning and then struck out the next hitter before being pulled. That the Twins are already calling the injury a strain suggests he could be out a while. Merryweather is in Twins camp as a non-roster invitee.

Bickford was shut down from throwing Tuesday due to a triceps strain, Chris McCosky of The Detroit News reports.

Bickford joined Detroit on a minor-league contract in January but is now dealing with an arm injury early in camp. The right-hander was already a longshot to crack the Opening Day roster, and the injury likely guarantees he'll open 2026 at the Triple-A level.

Stephenson (shoulder) said Tuesday he believes he'll be ready for Opening Day, Rhett Bollinger of MLB.com reports.

He threw another bullpen session Monday after showing up to camp behind schedule due to a nerve issue and thoracic outlet syndrome symptoms he experienced this offseason. It remains to be seen if Stephenson's stuff has suffered as a result of these physical issues, as he has not made his Cactus League debut yet.

Joyce (shoulder) will throw another bullpen session Wednesday, likely only throwing fastballs and changeups, Rhett Bollinger of MLB.com reports.

Joyce said Tuesday that his throwing progression is going well, but he's not yet ready to incorporate sliders into his routine. It's not clear whether he'll be ready in time for Opening Day, but he continues to make steady progress.

Ferrer was charged with the loss in Monday's Cactus League matchup with the Dodgers. He allowed two runs on three hits and a walk while striking out one in one-third of an inning.

It certainly wasn't the ideal start to the spring for Ferrer. The lefty struck out Andy Pages to open the frame before surrendering three straight hits, including a pair of doubles, followed by a walk and a wild pitch. The Mariners are hoping that Ferrer can shake off the rust before Opening Day, as he's expected to play a key role in the back end of their bullpen. Ferrer was traded to Seattle in December after posting a 4.48 ERA with a 1.27 WHIP and 71:16 K:BB across 76.1 innings with the Nationals in 2025.
