Giants optioned 1B Brett Pill to Triple-A Fresno.
Orioles transferred Brian Roberts (hamstring) from the 15-day disabled list to the 60-day disabled list.
It's just a procedural move to clear a spot on the 40-man roster. Roberts underwent surgery last Thursday to repair a ruptured tendon in his right knee and is expected to be sidelined for at least the next six weeks.
Orioles placed OF Nolan Reimold on the 15-day disabled list, retroactive to May 12, with a right hamstring strain.
It's the reason why Reimold was held out of the Orioles' lineup for the fifth straight day Saturday. Chris Dickerson will likely get the majority of starts at designated hitter in his absence. Given his injury history, Reimold could be looking at an extended stay on the DL.
Reds recalled 1B Neftali Soto from Triple-A Louisville.
Soto, 24, has shown good power potential over his seven-year minor league career and will provide corner infield depth. He was batting .269/.310/.388 with three home runs in 33 games at the Triple-A level.
Reds optioned LHP Tony Cingrani to Triple-A Louisville.
The Reds need to clear a rotation spot with Johnny Cueto set to return from the disabled list Monday, so Cingrani will officially be sent down. He was mostly impressive over his first six major league starts, posting a 3.27 ERA, nine walks and 41 strikeouts over 33 innings. Neftali Soto has been called up to replace Cingrani on the active roster, while Mike Leake will remain the team's fifth starter.
Orioles recalled RHP Jake Arrieta from Triple-A Norfolk.
Arrieta was scheduled to start for the Orioles' Triple-A affiliate, but will instead serve as bullpen depth for Saturday's game. The 27-year-old has a 6.63 ERA over 12 innings at the major league level this season.
Orioles optioned RHP Alex Burnett to Triple-A Norfolk.
Burnett lasted just three days on the Orioles' roster. He'll return to a 1.50 ERA in the minors.
Orioles purchased the contract of RHP Jair Jurrjens from Triple-A Norfolk.
Jurrjens will make his season debut Saturday against the Rays. He posted a 3.14 ERA in eight starts at the Triple-A level and will get his chance in the Orioles' rotation with Wei-Yin Chen on the disabled list. The 27-year-old right-hander should be monitored in AL-only leagues.
