SEATTLE -- Since the Red Sox arrived on the West Coast, it's as if every visiting clubhouse should come with a revolving door. Either because of performance or injury, the team has been involved in a flurry of roster activity.
On Wednesday, it was more of the same.
Out (optioned to Pawtucket) were pitchers Allen Webster and Alfredo Aceves.
In (promoted from Pawtucket) were pitchers Pedro Beato and Steven Wright.
"Given the number of moves we made in the bullpen (Tuesday) night,'' said manager John Farrell, "we have to make some moves to get some fresh arms here, being that we've been dealing with one less bullpen arm.''
Webster had a poor start Tuesday, lasting just 2 1/3 innings. In six starts, Webster has a 9.57 ERA.
Farrell said Webster's demotion was a combination of performance and needing a fresh arm in relief.
"As much as we felt like Allen was making solid progress and solid strides over the last couple of starts,'' said Farrell, "that first inning has been a challenge for him. To break it down further, the consistency of his fastball usage to both sides of the plate and executing that pitch to both sides of the plate is a fundamental area that's got to be improved upon.
"You can't debate (the quality of) the stuff; it's there. So this is as much about getting through the next four days, as well as the performance as well.''
Aceves pitched two-thirds of an inning in relief of Webster Tuesday, but didn't return for the next inning. Farrell said after Tuesday's game that Aceves was experiencing some "tightness'' in his left side, but said that wasn't the reason he came out of the game.
"By all accounts that we have,'' said Farrell, seeming to measure his words carefully, "he is not injured. Now, I will say this: that he felt some soreness in his left side before he came up here. But he was available to pitch and he was available to continue to pitch (Tuesday) night. But I felt like we needed to go to a lefthander to slow (the Mariners) down some. He didn't complain of anything after the game (Tuesday night), so this is a matter of getting two guys in here we know are capable of going multiple innings right away.''
Wright was 4-5 with a 3.81 ERA in 16 starts with Pawtucket and had a scoreless streak of 17 2/3 innings going.
Beato is on his third stay with Boston. In three previous appearances this season, he was unscored upon. At Pawtucket, he was 5-3 with two saves and a 2.18 ERA.
Webster's turn was supposed to come up again Sunday, the final day before the All-Star break.
Farrell said the Sox would consider Brandon Workman -- recalled from Pawtucket Tuesday -- and Wright would be among the candidates to take the start.
"That's not omitting anyone who might be on turn at Pawtucket,'' he said.
The near-constant shuffling of the bodies hasn't negatively impacted the Red Sox' clubhouse, Farrell said.
"This is a pretty strong core here,'' said Farrell. "The turnover's more on the pitching side, so seemingly, in the clubhouse, we haven't skipped a beat. There's some pretty strong personalities in there and I don't think a (new) guy coming in is going to strong-arm his way into the middle of it. But it's a positive environment as well.''
