Mariners right-hander Hisashi Iwakuma has left the team and traveled back to Japan for undisclosed “personal reasons.”
Geoff Baker of the Seattle Times reports that Iwakuma is expected to rejoin the team in time to make his next scheduled start, which is Monday against the Blue Jays, and might even be back in the United States as soon as Saturday.
Iwakuma was an afterthought for the Mariners’ pitching staff early on this season, often going long stretches without being used, but he eventually got an opportunity for a regular role and has thrown 51 innings with a 4.56 ERA split between the rotation and bullpen.
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.
