Los Angeles Angels manager Ron Washington will not manage the team for an indefinite period due to a health concern, general manager Perry Minasian told reporters on Friday.

The nature of Washington’s health ailment is undisclosed.

Bench coach Ray Montgomery will serve as interim manager, beginning with Friday night’s home game against the Houston Astros. Montgomery, 55, is in his fourth season on the Angels’ coaching staff.

Washington, 73, is expected to watch Friday night’s game from a suite inside Angel Stadium.

Washington is in his second season with the Angels and has a 99-137 record with the team. Los Angeles is 36-38 this season.

Overall, Washington holds a 763-748 record in 10 seasons. He guided Texas (2007-14) to the World Series in 2010 and 2011 with the Rangers losing each time.

The Angels also placed right fielder Jorge Soler (back) on the 10-day injured list, retroactive to Wednesday. The 33-year-old is batting .207 with eight homers and 26 RBIs in 67 games this season and has 199 career homers in 12 seasons.

Los Angeles recalled outfielder Gustavo Campero from Triple-A Salt Lake in a corresponding move. He was batting .320 with two homers and 17 RBIs in 32 games with the Bees.

Campero, 27, is batting .232 with one homer and six RBIs in 18 major league games over the past two seasons.
