Making official what was expected, the Red Sox announced that Alfredo Aceves will step into the rotation for the injured John Lackey, with his first start scheduled for tomorrow night against the Orioles.
Felix Doubront will slide back one day, starting Friday against the Rays in what was Lackey’s actual spot in the rotation. And for now at least the Red Sox haven’t placed Lackey on the disabled list, leaving open the possibility that he could return after missing just one or two starts.
Aceves threw 3.1 innings in relief after Lackey exited clutching his arm Saturday, so he’s stretched out enough to throw five-plus innings, but he hasn’t started a game since 2011 and has just nine career starts at age 30.
Pirates right-hander Joe Musgrove is done for the year after suffering an abdominal wall muscle strain and stress reaction in his pelvic bone. While he isn’t expected to undergo surgery or miss additional time in 2019, he’s been prescribed six weeks of rest before resuming any baseball-related activities.
Musgrove, 25, finished out his third year in Pittsburgh with a 6-9 record in 19 starts, backed by a 4.06 ERA, 1.8 BB/9, and 7.8 SO/9. Despite logging a career-high 115 1/3 innings at the major league level, he’s also been dogged by a string of injuries, from the shoulder strain that robbed him of eight weeks at the start of the season to an index finger infection that kept him sidelined for a minimum 10-day stay on the disabled list in June.
While he works his way back up to full strength yet again, rookie right-hander Nick Kingham is expected to cover for him and will make a spot start during the Pirates’ series finale against the Brewers on Sunday. The 26-year-old righty hasn’t started a single game for the team since August 1, and currently carries a 4.69 ERA, 2.7 BB/9, and 8.1 SO/9 over 71 innings out of the rotation and bullpen.
