Treinen gets shot at 8th-inning role

By Andrew Simon

WASHINGTON — From 2010-14, Tyler Clippard averaged 74 appearances out of the Nationals bullpen. Other than a stint as closer in 2012, he did most of his work as a set-up man, pitching in the eighth inning nearly 50 times per year over that stretch.

On Wednesday night, the Nationals led the Mets, 2-1, heading into the eighth. This would have been Clippard’s spot, but he was traded to the A’s during the offseason, and Drew Storen took over for Rafael Soriano at closer. That left manager Matt Williams without a clear right-handed option for the eighth inning, to use alongside lefty Matt Thornton.

At least on this day, Williams turned to Blake Treinen, a 26-year-old righty with 15 games of Major League experience, including eight relief appearances. The manager said that was his plan coming into the game, and it worked, as Treinen tossed a scoreless inning, and the Nats won, 2-1.

This was a new experience for Treinen, who mostly started in the Minors. Of his eight times working out of the bullpen last year, all but one came in a Nats loss or blowout win. Baseball-Reference.com’s average leverage index, which measures the pressure during a pitcher’s outing, puts Wednesday’s appearance as the highest-leverage of Treinen’s young career.

“Even last year in the bullpen, I didn’t really come in for one-run leads,” Treinen said. “So its still new, but I enjoyed it

“It’s something I’ll get adjusted to. I don’t think it bothers me. I enjoy those moments.”

Treinen tries not to approach things much differently out of the bullpen. But a short stint can allow him to dial up his velocity while focusing on his sinker and slider and pushing aside his third pitch, a changeup.

On Wednesday, Treinen threw two sliders and 11 sinkers, which averaged a blazing 97.7 mph, according to BrooksBaseball.net. The Mets did hit a couple of balls hard, with David Wright ripping a one-out single to right before Lucas Duda lined into an inning-ending double play.

But for context, of all pitchers who threw at least 200 sinkers last year, PITCHf/x measured only two who topped that average velocity. Treinen’s stuff certainly impressed Williams, who envisions him as a big part of the bullpen.

“He’s running the ball in there at 98 mph with some good sink,” Williams said afterward. “I’m happy with the way he went about it tonight. Certainly be more opportunities for him.”
