Jon Lester was supposed to be on the hill Wednesday at Fenway Park. Instead, Brandon Workman will be called up from Triple-A to start against the Blue Jays in the series finale.
The decision comes as no surprise. Red Sox manager John Farrell mentioned it was a possibility before Tuesday's game between Boston and Toronto because of the potential that Lester could be traded before Thursday's 4 p.m. ET non-waiver Trade Deadline.
"In light of all the uncertainty surrounding Jon Lester, it's probably in everyone's best interest that he does not make that start," Farrell said. "So, Brandon will be recalled."
Workman has made eight starts for Boston this season, including five straight in the rotation from late May to early June while Clay Buchholz was on the disabled list. He went 1-3 with a 4.50 ERA in that span.
Meanwhile, left-hander Mark Buehrle gets the nod for the Blue Jays, who are seeking the sweep and their fifth consecutive win, after what could be considered his worst start of the season. He allowed six runs on nine hits in three innings on Friday against the Yankees for the loss.
Buehrle is winless since June 1, posting a 4.95 ERA in that span. During the first two months of the season, he went 9-1 with a 2.33 ERA.
"I don't feel like I've thrown [bad enough] not to get a win in the last two months," Buehrle said after his last start. "Obviously these last couple of outings, I have, I've pretty much tanked. But before that, I felt like I was throwing pretty good.
"I think the ball's not going to guys, it's finding holes now. When you're going lucky, when you're going good, those balls go to your defensive guys. The bloop singles, when you make pitches, they're not making you pay for them."
Blue Jays: Rasmussen optioned
Left-hander Rob Rasmussen was optioned to Triple-A Buffalo on Tuesday to make room for recently acquired infielder Danny Valencia.
The move leaves Toronto with six men in its bullpen. However, the number shouldn't stay that way for long. Another reliever will likely join the bullpen in the next few days.
"Day to day, if it blows up on us, we're good now ... of course, we'd have to make a move then," Gibbons said before Tuesday's game when asked about the status of his bullpen and whether the club will need to add another reliever soon.
Red Sox: Farrell talks to Doubront
After Felix Doubront imploded on the mound Monday night against the Blue Jays, allowing six runs on six hits in two-thirds of an inning, Farrell said Tuesday that he'd met with the left-hander. The conversation specifically focused on Doubront's demeanor on the hill.
"Yes, and that's all I'll say about it," said Farrell.
Doubront has made 66 starts for Boston over the last three seasons, including 10 in 2014. He hasn't started since June 20 and has made seven relief appearances since.
• Boston's Dustin Pedroia has three multi-hit performances in his last six games. He's hitting .364 in that stretch.
• Jose Bautista has hit 28 career home runs against Boston, the most against any opponent. Eighteen of those long balls have come at Fenway.
