Injuries
- Washington Nationals left fielder Bryce Harper will receive thumb surgery on Tuesday to repair a torn ulnar collateral ligament, according to ESPN's Keith Law. The surgery will sideline Harper until at least early July, a span of roughly two months. The Nationals, who are already without star players Doug Fister and Ryan Zimmerman, will have to make due in Harper's absence, which certainly puts the team in a tough spot in its quest for a playoff berth.
- The San Diego Padres officially placed third baseman Chase Headley on the 15-day DL, retroactive to April 25, with a right calf strain, the team announced.
Roster Moves
- The St. Louis Cardinals recalled Randal Grichuk and Greg Garcia from Triple-A Memphis, optioning second baseman Kolten Wong and right fielder Shane Robinson to Triple-A, the team announced. Grichuk, a 22-year-old outfielder who came over in the David Freese trade, was batting .310 with an .880 OPS at Memphis prior to his call-up. With Wong struggling at the plate and center fielder Peter Bourjos looking similarly lost at the plate, Grichuk's promotion looks like an attempt to inject some much-needed offense into the Cardinals lineup.
- The San Diego Padres placed second baseman Jedd Gyorko on the paternity list, recalling first baseman Tommy Medica from Triple-A El Paso, according to MLB.com's Alex Espinoza IV.
- The Toronto Blue Jays optioned Ryan Goins to Triple-A Buffalo, per a team announcement. The Jays will make a corresponding roster move on Tuesday.
Trades
- The Houston Astros traded right-hander Lucas Harrell to the Arizona Diamondbacks for a player to be named later or cash considerations, the team announced.
Miscellaneous
- Rehab Assignments: Logan Schafer (LF, Cardinals) to Single-A Brevard County, Skip Schumaker (2B, Reds) to Triple-A Louisville, Juan Lagares (OF, Mets) to Triple-A Las Vegas
- Oakland A's right-hander Sonny Gray pitched a complete-game shutout, limiting the Texas Rangers to just three hits and a walk in a 4-0 victory. Gray improved his ERA to 1.76 while picking up his fourth win of the season.
- Colorado Rockies shortstop Troy Tulowitzki went 3-for-3 with a home run, three RBI and a pair of walks as the Rockies defeated the Diamondbacks, 8-5.
