Mason Barnett - MLB News, Rumors, & Updates

Garnering another start Athletics manager Mark Kotsay said Sunday that Barnett will maintain his spot in the rotation during the upcoming week, Jason Burke of Roundtable.io reports.

Impact After coming up from Triple-A Las Vegas on July 22, Barnett entered the rotation last weekend and tossed 3.1 innings of bulk relief in a 2-0 loss to the Twins. He then handled a traditional starting role for his next appearance Thursday, limiting a red-hot Red Sox squad to three runs on four hits and one walk while striking out six over five innings. He's earned himself a more permanent stay in the rotation, even though the Athletics will get J.T. Ginn (finger) back from the 15-day injured list Tuesday. Kotsay confirmed that the Athletics won't be moving to a five-man rotation, so one of Jeffrey Springs, Jack Perkins, Jacob Lopez and Gage Jump would appear to be in line to lose his starting role.

Fans six in no-decision Barnett allowed three runs on four hits and one walk while striking out six batters over five innings in a no-decision against Boston on Thursday.

Impact After working in bulk relief in his previous appearance, Barnett made his first start of the season Thursday. He got through four scoreless frames before fading in the fifth, when the Red Sox tagged him for three runs on three hits. That ended up being his final frame, and he threw 73 total pitches, his highest mark in a big-league game so far this season. Barnett may not be ready for a completely full workload yet, and he could return to the bullpen when J.T. Ginn (finger) is activated from the IL, which could happen early next week.

Covers 3.1 frames in bulk relief Barnett (1-1) took the loss against Minnesota on Saturday, allowing two runs on four hits and one walk while striking out two batters over 3.1 innings.

Impact Initial reports suggested Barnett would start Saturday's contest, but that role ultimately went to Brady Basso, who covered the first two frames. Barnett still ended up logging the longest outing among A's pitchers, tossing 54 pitches (35 strikes) across his 3.1 innings. The right-hander got through his first three frames unscathed, but he surrendered two runs in the sixth, which accounted for all of the scoring in the game. It remains to be seen how Barnett will be deployed moving forward, but he could be needed to make a few starts (or bulk-relief appearances) with J.T. Ginn (finger blister) currently on the 15-day IL.

No longer starting Saturday Barnett is not listed as the Athletics' starter for Saturday's game against the Twins.

Impact Jason Burke of Roundtable.io originally reported that Barnett would start Saturday. Instead, it'll be left-hander Brady Basso who will serve as the opener in what is shaping up to be a bullpen game for the Athletics. Barnett has a 4.64 ERA and 1.34 WHIP over 21.1 innings this season.

Handling starting role Saturday Barnett is slated to start Saturday's game against the Twins at Target Field, Jason Burke of Roundtable.io reports.

Impact The Athletics called Barnett up from Triple-A Las Vegas on Wednesday, and after he wasn't needed in relief over the past three days, he'll end up slotting into the rotation as a replacement for the injured J.T. Ginn (finger). Barnett was a full-time member of the rotation at Las Vegas prior to his call-up, but all 13 of his appearances with the Athletics in 2026 have come out of the bullpen. As Burke notes, Barnett was limited to 38 pitches in his most recent start for Las Vegas on July 18, so the right-hander will likely be in store for a restricted workload in Saturday's outing.

Back with big club The Athletics recalled Barnett from Triple-A Las Vegas on Wednesday.

Impact Barnett is grabbing the roster spot vacated by the injured J.T. Ginn (finger). He's also a candidate to take Ginn's rotation spot even though all 13 of his appearances in the majors this season have been in relief. Barnett has made 10 starts in 2026 with Las Vegas, posting a 4.34 ERA and 42:26 K:BB over 45.2 frames.

Relegated to Triple-A The Athletics optioned Barnett to Triple-A Las Vegas on Wednesday, Jason Burke of Roundtable.io reports.

Impact Barnett ended the first half by giving up three runs in one inning against the White Sox. Now sporting a 4.64 ERA and 1.36 WHIP through 21.1 innings in the big leagues, he'll head back to Las Vegas to begin the second half but remains an option to return to Sacramento later in the year to provide bullpen depth.

Picks up second save Barnett earned the save in Thursday's 9-6 win over the Giants, striking out one in a perfect ninth inning.

Impact It's Barnett's second save in his first eight appearances in the majors this season. The 25-year-old right-hander has quickly ingratiated himself in the A's bullpen, allowing just two runs on seven hits and seven walks while striking out 19 in his first 14.2 innings. Barnett made five starts with Triple-A Las Vegas earlier in the year, where he posted a 4.64 ERA over 42.2 innings.

Secures two-inning save Barnett struck out four over two perfect innings to earn the save in Tuesday's 7-5 win over the Brewers.

Impact Barnett wasn't utilized in Monday's slugfest, leaving him fresh to pitch Tuesday while the bullpen was short. He delivered a tidy outing, collecting his six outs on 31 pitches (20 strikes) for his first career save. Barnett has allowed just two hits with a 12:4 K:BB across eight innings over three relief appearances this season. The Athletics have a hole in the rotation currently, but it may not be an issue until next week. Barnett came up through the minor leagues as a starter, which could make him a candidate for a spot start at some point later in the year. For now, he can be considered a long reliever.

Stellar in relief Friday Barnett allowed a hit and two walks while striking out seven over four scoreless innings of relief in Friday's 5-1 loss to the Astros.

Impact Entering after four-plus innings of five-run ball from starter Jack Perkins, Barnett was able to pitch the remainder of the game and did so without allowing a run while recording a game-high seven strikeouts. It marked the right-hander's first big-league appearance since being recalled from Triple-A Las Vegas on Tuesday and just his second outing of the season, with the first consisting of two scoreless innings April 19. While this appearance came in relief, Barnett made five starts with the Athletics last season and has continued to operate primarily as a starter in Triple-A. That background could lead to starting rotation consideration if Perkins continues to struggle or Kade Morris is unable to establish himself.

Recalled from Triple-A The Athletics recalled Barnett from Triple-A Las Vegas on Tuesday.

Impact Barnett made one scoreless relief appearance for the Athletics earlier this season but has spent most of the year in the rotation at Las Vegas, holding a 4.64 ERA and 41:26 K:BB over 42.2 innings. He could get a chance to make some starts for the Athletics, though the club has not yet clarified what Barnett's role will be.

JUNE 2 • ROTOWIRE

Back in Vegas The Athletics optioned Barnett to Triple-A Las Vegas on Friday.

Impact After coming up from the minors Wednesday, Barnett will return to Triple-A without making an appearance for the A's in order to make room for the newly acquired Jose Suarez. The 25-year-old Barnett owns a 3.07 ERA and 1.27 WHIP over 29.1 innings at Triple-A this season and remains an option to come up later in the year for a spot start or to give the Athletics length out of the bullpen.

Recalled from Las Vegas The Athletics recalled Barnett from Triple-A Las Vegas on Wednesday.

Impact The 25-year-old will return to the majors to replace Brooks Kriske, who landed on the injured list Wednesday with a shoulder injury. Barnett pitched two shutout innings during his lone appearance with the A's this season in mid-April, and he owns a 3.07 ERA and 1.27 WHIP through 29.1 frames at Las Vegas. He'll likely take on a multi-inning role out of the bullpen while with the A's.
