Treinen allowed one hit and struck out three in 1.2 innings during Saturday's loss to the Reds. That's now nine straight scoreless appearances for Treinen, who has a strong 2.70 ERA, 1.24 WHIP and 25:10 K:BB in 23.1 innings this season. He doesn't get used in particularly high-leverage situations, however, and with no saves and only five holds his fantasy value is somewhat limited. If injuries or trades were to shake up the Nats' bullpen, Treinen might end up being the biggest beneficiary.
Treinen struck out two and walked one in a scoreless ninth inning against the Royals on Wednesday. It wasn't exactly a high-leverage situation, as the Nats were up 13-2 at the time, but the outing still dropped Treinen's ERA to 3.27. He also has five holds to go along with a 1.27 WHIP and 12:6 K:BB in 11 innings, but Dusty Baker seems to be using him more as a short-relief jack-of-all-trades than a consistent setup man, so Treinen may not be able to keep up that pace in holds even if he continues pitching well.
Treinen (1-0) worked a scoreless ninth inning Monday, walking one and striking out one, to pick up the victory in an extra-inning win over the Braves. The Nationals' presumed setup men, Shawn Kelley and Felipe Rivero, both struggled Monday, with Kelley looking especially bad. It's too early to anticipate a shake-up in the bullpen pecking order, but if Treinen continues to be effective he could work his way into more high-leverage situations.
Treinen has won the final spot in the Nationals' bullpen, The Washington Post reports. He beat out Trevor Gott, who was optioned down to Triple-A, and Sean Burnett for the job. Treinen will likely be used in middle relief and as an occasional set-up man.
Treinen is competing with Trevor Gott and Sean Burnett for one or possibly two spots in the Nationals' Opening Day bullpen, Jamal Collier of MLB.com reports. His power sinker allowed him to post a 3.86 ERA, 1.39 WHIP and 65:32 K:BB in 67.2 innings last season and he was assumed to have a bullpen role locked up coming into spring training, but the club's decision to add non-roster invitee Matt Belisle to the 25-man roster could put Treinen's spot in jeopardy. Treinen and Gott both have minor league options remaining, which may become a factor if Burnett, another non-roster invitee, also gets a job. Treinen's enjoyed an excellent spring, however, posting a 0.00 ERA and 8:1 K:BB in eight innings, so if it comes down to performance he should be safe.
