As anticipated from the moment the injury was announced. Jon Lester has been placed on the disabled list with a strained lat muscle suffered in the fourth inning of his start against the Blue Jays last night.
Reliever Scott Atchison has been called up to take his place on the roster.
Lester takes a 10-4 record and a 3.31 ERA with him to the DL. The Red Sox will need to replace him in the rotation Sunday against the Orioles. Depending on whether he’s needed out of the pen, Alfredo Aceves could make that start. He’s 1-1 with a 5.14 ERA in his four starts this season.
An alternative would be Kevin Millwood, who would pitch on six days’ rest. He gave up three runs over seven innings in his last start for Triple-A Pawtucket, and is 4-0 with 4.15 ERA overall in seven starts for the club.
Judging by the way Lester finished his outing last night, the strain he suffered couldn’t have been particularly severe. The Red Sox haven’t provided a timetable for his return, but it’s possible he’ll miss just two or three starts.
It’s Lester’s first trip to the disabled list since 2007.
The Blue Jays placed right-hander Aaron Sanchez on the 10-day disabled list with a contusion in his right index finger, per a team announcement on Saturday. The assignment is retroactive to Friday. In a corresponding move, righty Marcus Stroman was activated from the DL (right shoulder fatigue) and will take the mound for the Blue Jays at 9:07 PM ET tonight.
Sanchez, 25, is in his fifth season with the club. He hasn’t looked his sharpest so far this year, going 3-5 in 15 starts with a career-worst 4.52 ERA, 5.1 BB/9 and 7.6 SO/9 through 79 2/3 innings. It’s not yet clear how long he’ll be sidelined, though he could miss as little as one turn in the rotation before returning to the roster in the next week or two.
Sanchez isn’t the only struggling starter in Toronto’s rotation, either. Per MLB.com’s Gregor Chisholm, the team placed southpaw Jaime Garcia on the DL (right shoulder tenderness) as well, with lefty reliever Tim Mayza scheduled to take his spot on the roster. In 13 starts this season, Garcia carried a 2-6 record, 6.16 ERA, 4.5 BB/9 and 8.2 SO/9 over 61 1/3 innings. Any further decisions pertaining to the rotation — including Tuesday’s starter against the Astros — have yet to be publicly addressed.
