Mason Barnett Fantasy Stats

Athletics pitcher Mason Barnett was handed the ball with a three-run lead in the ninth inning of Thursday's game against the San Francisco Giants. The A's were trailing this game until scoring four runs in the top half of the ninth inning. They turned to Barnett in the bottom half with an easier assignment given the three-run cushion. He retired all three batters in order, recording a strikeout and earning his second save of the season. Barnett has allowed only two runs while striking out 19 batters across 14.2 big league innings this season. He figures to remain in the mix as a closer, but is more of a deep league option right now.

Athletics pitching prospect Mason Barnett will make his major-league debut on Saturday and start against the division-rival Texas Rangers, according to manager Mark Kotsay. Barnett, the team's 10th-ranked prospect per MLB Pipeline, will get the call to the big leagues for the first time after going 6-2 with a 6.13 ERA, 1.59 WHIP and 124:65 K:BB in 119 innings over 25 appearances (23 starts) for Triple-A Las Vegas in the hitter-friendly Pacific Coast League. With lefty Jacob Lopez (elbow) on the injured list, the 24-year-old right-hander will be auditioning for a starting rotation spot for the A's for the final month of the 2025 campaign. The Rangers are a friendly matchup for opposing starters, but Barnett will only be a streaming option for the desperate in DFS and deep fantasy leagues. The 6-foot, 218-pounder mostly relies on a mid-to-high-90s fastball, a sweeperish slider, a curveball and a changeup.

The Athletics promoted right-handed pitching prospect Mason Barnett after placing left-handed pitcher Jacob Lopez on the injured list. Barnett is the Athletics' number 11 overall prospect according to MLB.com, and his role is still to be determined. His numbers are poor at Triple-A Las Vegas this year, owning a 6.13 ERA, 1.60 WHIP, and a 10.8% K-BB% in 119 innings. The right-hander is striking out fewer hitters and walking more than he has at any stop in the minors this season. He's coughed up six runs in each of his last two outings in what has been a tough month of August. Given the role uncertainty and unfriendly home ballpark, Barnett doesn't profile to be relevant for fantasy purposes except in the deepest of leagues.
