ANAHEIM, Calif. _ The hard collision between slugger Joey Gallo and reliever Matt Bush on Sunday afternoon has knocked Bush (knee sprain) to the disabled list. Both were placed into MLB's concussion protocol after the collision. Gallo also suffered a nasal fracture.
The Rangers recalled outfielder Ryan Rua from Triple-A Round Rock and purchased the contract of right-handed reliever Nick Gardewine from Double-A Frisco to replace them.
Gallo began Monday tied for second in the AL in home runs with Kansas City's Mike Moustakas at 35. They were two behind New York's Aaron Judge. Gallo and Seattle's Nelson Cruz each have 14 home runs since the All-Star break to lead the AL.
With Gallo and Carlos Gomez (cyst) currently out of the lineup, it is likely that Drew Robinson and Rua will form something of a left-right platoon in left field. Delino DeShields has been playing center field regularly.
Rua spent the first 10 weeks of the season in the majors, but hit only .202 in 99 at-bats. He was called back up on July 31, but did not appear in a game during 11 days with the team and was sent back to Round Rock. He lost playing time earlier this year due to a lack of success against lefties in a limited role, batting only .217 with a .598 OPS.
Gardewine, who turned 24 on Aug. 15, is the second August bullpen call-up to go straight from Double-A to the majors. He joins Ricardo Rodriguez, who was called up two weeks ago. The common denominator: Both have been extreme strike throwers.
Gardewine has walked 12 batters in 33 innings this year and just three in 17.1 innings since July 1. A seventh-round pick in 2013, Gardewine has a fastball in the 93-95 mph range and compliments it with a hard slider.
