Elias Diaz underwent a debridement procedure Tuesday on his injured right elbow.
That's a fairly minor surgery, considering the alternatives. Diaz, a 25-year-old catcher, will likely be shut down for the next 7-9 weeks. He is already on the 15-day major league disabled list.
Ben Revere (oblique) played a full nine innings of center field Tuesday at Triple-A Syracuse.
And he went 1-for-5 at the plate. It was Revere's fifth minor league rehab game, but only his first time playing all nine innings. The speedy center fielder is due to rejoin the Nats this weekend in Chicago.
Nick Markakis is out of the Braves' starting lineup on Wednesday due to a family emergency.
Markakis has been excused from the club to travel back to his home in Maryland, though he's expected to return for the Braves' weekend series against the Diamondbacks. Atlanta has a scheduled day off Thursday.
Ryan Braun is back in the Brewers' starting lineup on Wednesday afternoon against the Angels.
Braun was given the day off Tuesday due to some routine soreness. He will start in left field and bat third Wednesday versus Angels left-hander Hector Santiago. Braun, 32, is slashing .372/.443/.605 this season.
Tommy Pham (oblique) is scheduled to begin a rehab assignment Wednesday with Triple-A Memphis.
Pham is finally ready for live action again after missing a full month with a strained left oblique. He should rejoin the Cardinals as an active backup outfielder early next week. The 28-year-old has a cool .809 OPS in 176 career major league plate appearances and he can play all three outfield spots.
