Treinen (1-1) pitched 1.2 clean innings and stuck out three to earn the win Sunday against the Red Sox. Treinen entered a tied game in the eighth inning and inherited a runner on first. However, he proceeded to strike out the first two batters he faced and then continued on to pitch a clean ninth inning to earn his first win of the season. The Athletics haven't hesitated to use him across multiple innings this season as he has recorded more than three outs in six of his seven appearances. Despite two blown saves early on, Treinen remains locked into the closer role.
Treinen notched his third save in a 2-1 win over the Mariners on Sunday, recording a strikeout over 1.1 scoreless innings. Treinen needed just 16 pitches -- 12 of which he threw for strikes -- to get four outs. He got the Athletics out of a jam in the eighth upon entering the game, eliciting an inning-ending flyball from Jean Segura with Dee Gordon and Andrew Romine in scoring position. Treinen followed up by mowing down the dangerous trio of Robinson Cano, Nelson Cruz and Kyle Seager in the ninth, keeping his ERA unblemished through five appearances. Sunday's effort was also the 29-year-old's first clean outing of the season, as he'd allowed at least one hit in each of his other four trips to the mound.
Treinen tossed a pair of scoreless innings Saturday against the Angels en route to his second save of the season. He struck out four. The veteran was called upon to face the meat of the order in the eighth inning and emerged unscathed. An extra run of insurance prompted the Athletics to leave him out for the ninth, and he managed to escape the inning despite putting a pair of runners on base. Treinen has yet to allow an earned run this year and holds a 7:2 K:BB in six innings of work, though his 1.50 WHIP is a bit troubling.
Treinen allowed a hit and a walk across 1.2 scoreless innings to earn his first save of the season Monday against the Rangers. He recorded one strikeout. Treinen entered with the tying run on base in the eighth inning, striking out Robinson Chirinos before recording a hard out from Rougned Odor to end the frame. He made things interesting in the ninth, putting two men in scoring position with one out before closing things out. Treinen has allowed five baserunners in 3.2 innings over two appearances this season, but he's still yet to allow a run.
Treinen, who is in line to be the designated closer to open the season, fired a scoreless inning in which he allowed a hit and recorded a strikeout in Tuesday's 8-2 Cactus League loss to the Dodgers. It's a continuation of what's been a strong exhibition slate for Treinen, one that's seen him allow just one earned run over seven appearances, leading to a 1.42 ERA. Treinen accumulated 16 saves and 10 holds with the Nationals and Athletics in 2017, and a chance to potentially operate as a closer for a full season for the first time in his career brightens his fantasy prospects considerably.
