Tavarez fills in, will start vs. O's

Tavarez fills in, will start vs. O's

When the Red Sox traded Wednesday night's original starter -- Kason Gabbard -- to the Rangers as part of the package that landed Eric Gagne, it didn't take long to solve the bind of who would pitch on such short notice.

Julian Tavarez, welcome back to the rotation. It will be just a one-start cameo for the rubber-armed righty, as Curt Schilling is set to reclaim his post when he comes off the disabled list on either Sunday or Monday.

After 18 starts, Tavarez was moved to the bullpen on July 22 to make way for the return of Jon Lester.

"He's proved his value," said Red Sox catcher Jason Varitek. "He's given us some tremendous starts. He's just been a valuable arm to us all year, most of it's been as a starter. Hopefully, he can continue to do that."

How does Tavarez so easily bounce between starting and relieving?

"It's mental," said Tavarez.

In this one, Tavarez will be opposed by Steve Trachsel. The Red Sox will aim to snap a two-game losing streak. Gagne is likely to be activated before the game.

Pitching matchup
BOS: RHP Julian Tavarez (6-8, 5.08 ERA)
Tavarez, who made 18 starts before moving to the bullpen on July 22, will make his first start since July 18. In that contest against the Royals, he gave up nine hits and six runs (four earned) over 4 2/3 innings. In three appearances in relief, Tavarez surrendered no earned runs. Lifetime against the Orioles, Tavarez is 2-3 with a 4.68 ERA.

BAL: RHP Steve Trachsel (5-7, 5.26 ERA)
Trachsel looked very hittable -- again -- in his last start, continuing his troubling trend of poor performances. The veteran righty lasted only 4 2/3 innings and surrendered five runs -- including two homers -- on seven hits to the Rays. Even working with a sizable lead for most of the outing, he couldn't get through many innings unscathed. Trachsel was hit hard, as eight Rays hit into flyouts and 10 reached base with Trachsel on the mound. Over his last six outings, he has a 9.23 ERA and has pitched into the seventh inning only once.

Player to watch
Sox third baseman Mike Lowell is 10-for-29 lifetime against Trachsel.
