2:45pm: Manager Aaron Boone tells reporters that Stanton initially felt discomfort following a swing in Sunday’s game against the Orioles (Twitter link via James Wagner of the New York Times). A postgame MRI revealed a Grade 1 strain. While an exact timetable isn’t known, Stanton will be out longer than the minimum 10 days. The YES Network’s Jack Curry tweets that Stanton will be shut down entirely for the next 10 days. The organization’s hope is that he can return before the end of April.

10:05am: The Yankees announced Monday that they’ve placed outfielder/designated hitter Giancarlo Stanton on the 10-day injured list due to a left biceps strain. In his place, Clint Frazier has been recalled from Triple-A Scranton/Wilkes-Barre. There’s no word yet from the team on the severity of Stanton’s injury or how long he is expected to be out of action.

There was no clear indication that Stanton was dealing with an injury early in the season. The slugger has a pair of hits in eight official at-bats so far but has also drawn a walk in seven of his 15 plate appearances on the young season, giving him a .600 on-base percentage through three games. The injury is a tough early blow to a Yankees club that already is already without Luis Severino, Aaron Hicks, Dellin Betances, Didi Gregorius and CC Sabathia to open the season. New York torched the Orioles in the season opener but dropped the next two games to lose the year’s first series. They’ll face the Tigers, the Orioles a second time (in Baltimore) and then the Astros (in Houston) over the next 10 days without Stanton in the fold.

With Stanton now shelved alongside Hicks and Jacoby Ellsbury, the Yankees will lean on Brett Gardner, Aaron Judge, Frazier and Mike Tauchman in the outfield mix for at least their next three series (barring any waiver claims or other additions). The injury to Stanton should allow the club to more easily work both Luke Voit and Greg Bird into the lineup at times, and it could also present some more at-bats for offseason acquisition DJ LeMahieu.

The 24-year-old Frazier, meanwhile, will get an early opportunity to rebuild some stock after a 2018 season that was marred by ongoing concussion symptoms. The longtime top prospect received only 41 plate appearances in the Majors, though he certainly held his own, batting .265/.390/.353. In 242 minor league plate appearances last season, Frazier posted an outstanding .305/.388/.562 batting line.
