The Tigers purchased De Jesus' contract Tuesday, adding him to the 40-man roster, Evan Petzold of the Detroit Free Press reports.

The left-hander joined Detroit as a non-roster invitee in December, and he allowed three unearned runs with seven strikeouts and one walk across 6.1 innings during spring training. He also allowed just one run while striking out eight over five frames in his start for Venezuela in the World Baseball Classic. De Jesus made his MLB debut in 2023 with two appearances for Miami but spent the past two seasons pitching in the Korea Baseball Organization.

Hader (biceps) said that it was "all positives" during a 15-pitch bullpen session Tuesday, Brian McTaggart of MLB.com reports.

Throwing from the mound for the first time since he developed left biceps inflammation prior to reporting to Astros camp, Hader was pleased with his velocity, the action on his pitches and his mechanics during the bullpen session. When asked about his potential availability for Opening Day, Hader didn't dismiss the possibility, saying only, "we'll see." The consensus is that a stint on the 15-day injured list to begin the season is likely, but it's possible Hader could change the Astros' minds if he looks good over the next couple weeks.

Mears allowed three runs on three hits over one inning in Monday's Cactus League loss to the Guardians.

Mears was done in by the long ball, surrendering back-to-back homers to Steven Kwan and Brayan Rocchio with two outs in the fifth inning. After being acquired by the Royals from the Brewers in December, the reliever has made four Cactus League appearances, allowing four runs on four hits and two walks across four innings, with Monday's outing accounting for much of that damage. Coming off a 3.49 ERA and 0.97 WHIP across 56.2 regular-season innings last year with Milwaukee, Mears figures to slot in as a middle-relief option in the Kansas City bullpen for 2026.

Cruz allowed no hits or walks across 1.1 scoreless innings in Monday's Cactus League loss to the Guardians.

Cruz entered to record the final out of the seventh inning before retiring the side in order in the eighth frame. Monday marked his third scoreless outing of the spring, though it was the first time the right-hander failed to record a strikeout after punching out a pair in each of his first two appearances. The 26-year-old's fastball, which averaged 98.2 mph last season, sat at 96.6 mph against the Guardians, though velocity dips during spring training are common and not overly concerning unless they persist into the regular season. Cruz will look to continue producing strong results in Cactus League play as he competes for a spot in the big-league bullpen to open the 2026 campaign.

Crochet allowed three runs on five hits while striking out two over 4.2 innings in Monday's spring start against the Phillies. He also hit a batter.

Crochet's third Grapefruit League start didn't yield pretty results, but the left-hander was pleased overall with his execution, per Sean McAdam of MassLive.com. His velocity was down, but Crochet explained that was more a function of building arm strength and tinkering with mechanics. Philadelphia touched him for two runs in the second inning, which were aided by a couple of softly hit, well-placed singles. A third run was charged to him when a runner stole home after Crochet departed the game. Pitching into the fifth inning and hitting 59 pitches (42 strikes) leaves Crochet on schedule for Opening Day against the Reds on March 26.

Alberto won't make a scheduled appearance Monday versus the Rockies due to back tightness, James Fegan of SoxMachine.com reports.

Alberto is expected to be ready to pitch in a day or two, so he's not believed to be dealing with a significant setback. The 24-year-old is trying to win a bullpen spot with the White Sox after being plucked in the Rule 5 Draft. Alberto has yielded three runs with a 4:2 K:BB over five innings so far this spring.

The Athletics reassigned Hartlieb to minor-league camp Monday.

Hartlieb had been attending big-league camp as a non-roster invitee, but any hope he had of being part of the Athletics' Opening Day bullpen ended after he allowed eight runs (seven earned) over 2.1 innings across four Cactus League appearances. The 32-year-old is likely to serve as organizational relief depth at the Triple-A level throughout the 2026 season.

The Athletics reassigned Bowden (lat) to minor-league camp Monday.

Bowden had been attending Athletics camp as a non-roster invitee, but a left lat strain has kept him from pitching thus far in Cactus League play, effectively ending any chance he had of winning a spot in the Opening Day bullpen. The southpaw made 11 appearances for the big club in 2025, logging a 4.22 ERA, 1.31 WHIP and 7:5 K:BB In 10.2 innings.

Kolek (oblique) began playing catch from up to 60 feet Monday, Anne Rogers of MLB.com reports.

Kolek was shut down for more than a week after being diagnosed with a Grade 1 left oblique strain. He will be slowly ramped back up before returning to Cactus League action. The right-hander should be healthy for Opening Day, barring setbacks, but the injury has significantly lessened his chances of obtaining a spot in the Royals' rotation.

The Rangers optioned Otanez to Triple-A Round Rock on Monday.

Otanez took himself out of contention for a spot in the Rangers' Opening Day bullpen after yielding four earned runs on four hits and one walk over 2.1 innings across his three Cactus League appearances. The 28-year-old righty will serve as a leverage arm at Round Rock to begin the season while he waits for an opening to re-emerge in the Texas bullpen.
