Martin allowed one hit and struck out two over a scoreless eighth inning in Thursday's 6-4 win over Seattle on Opening Day.

Martin earned his first hold as the bridge to closer Kenley Jansen, who recorded the save. Martin threw just 2.1 innings during spring training due to a groin issue, but the right-hander was ready and available for the beginning of the regular season. He'll be the primary setup option for Boston in 2024.

Jansen earned a save against the Mariners on Thursday, issuing one walk and striking out two batters in a scoreless inning.

Jansen entered in the ninth inning with Boston holding a two-run lead and worked around a leadoff walk to close out the victory. The veteran closer missed most of spring training due to separate lat and back injuries, but that didn't prevent him from getting the call on Opening Day. Jansen's recent campaigns haven't been quite as dominant as his peak years with the Dodgers, but he's recorded 70 saves over the past two seasons and is locked in as Boston's closer as he pushes toward becoming the fourth pitcher in MLB history to reach 450 career saves.

Crochet (0-1) went six innings and took the loss Thursday against the Tigers, allowing one run on five hits and no walks. He struck out eight.

It was an impressive performance for Crochet, who earned the Opening Day nod despite having never made a start in his previous 72 big-league outings. The lefty struck out eight while going toe-to-toe with Kansas City's Tarik Skubal, who also tossed six innings but didn't yield a single run. Crochet is set for a tougher matchup his next time out, as he currently lines up to face Atlanta at home next week.

Wood (0-1) took the loss against Cleveland on Thursday, allowing six runs on seven hits and one walk while striking out three batters over 3.1 innings.

Wood got through three frames with just one run on his ledger, but he faltered in the fourth, allowing six straight batters to reach base with one out. The left-hander was pulled following Brayan Rocchio's two-run double, but by then he had given up five runs in the frame. Wood will be looked to for veteran leadership and rotation stability in his first campaign with the Athletics, though it remains to be seen how much he has left in the tank after compiling a 4.41 ERA over his previous three big-league seasons across the bay with San Francisco.

Ragans (0-1) tossed six innings of two-run baseball, allowing five hits and three walks while striking out nine while taking the loss Thursday against the Twins.

Ragans picked up where he left off in 2023 with more strikeouts than innings pitched Thursday, but he didn't receive much run support. The hard-throwing lefty started 12 games for the Royals last season after coming over in a mid-season trade from Texas and posted a 2.64 ERA with 89 strikeouts over 71.2 innings. He's expected to continue his ascent as one of the top young left-handed starters in the American League this season.

Robertson (1-0) picked up the win Thursday, working around a pair of walks in a scoreless inning against the Cubs. He struck out one.

Robertson kept Chicago off the board in the top of the 10th inning, working out of a bases-loaded jam, before Jonah Heim ended the game with a walk-off single in the bottom half of the frame. Jose Leclerc, who allowed a run in the ninth inning Thursday, is the presumed closer in Texas, though Robertson would be next in line and figures to see a fair amount of save chances this year. The 38-year-old right-hander tallied 18 saves across 65.1 innings between the Mets and Marlins last season, posting a 3.03 ERA, 1.19 WHIP and 78:25 K:BB.

Bradford will start Saturday's game against the Cubs, Jeff Wilson of RangersToday.com reports.

Bradford is in the Rangers' rotation as Michael Lorenzen (neck) builds up his workload. Barring an additional injury to the team's pitching staff, Bradford will shift to a relief role or be optioned to Triple-A Round Rock after a few turns as a starter. The left-hander made his big-league debut in 2023, posting a 5.30 ERA across 56 innings, though he managed a more impressive 1.21 WHIP and 51:12 K:BB.

Stewart threw a scoreless eighth inning to earn his first hold of the season in Thursday's Opening Day win at Kansas City.

It was Griffin Jax who got the first save chance of the season and converted with a scoreless ninth inning. It looks like Jax will be the primary option to close games while Jhoan Duran is sidelined several weeks with an oblique injury. However, the Twins could mix and match the two in save situations.

Jax threw a scoreless inning with a walk and strikeout to record the save in Thursday's Opening Day win at Kansas City.

With Jhoan Duran (oblique) on the injured list and expected to miss several weeks, it was Jax who got the call in the ninth inning to protect a three-run lead. Brock Stewart was used in the eighth inning, so it looks like Jax will be the primary closer with Duran out. However, the Twins could mix and match the two in save situations.

The Rangers placed Hernandez (lat) on the 15-day injured list Thursday.

The right lat strain that Hernandez suffered late in the 2023 regular season delayed his start to spring training, as he logged just 3.1 innings in Cactus League play before camp came to an end. According to MLB.com, general manager Chris Young said that the Rangers want to see Hernandez pitch multiple innings in a rehab game and work on back-to-back days before bringing him back from the IL. He'll be eligible for activation beginning April 9.
