Mariners activated LHP Tyler Olson from the 15-day disabled list; optioned him to Triple-A Tacoma.
Olson is recovered from his right knee injury, but there's no longer a spot for him in the Mariners' bullpen. The 25-year-old left-hander will go on serving as organizational relief depth for Seattle.
Mariners recalled LHP Mike Montgomery from Triple-A Tacoma.
Montgomery will make his major league debut Tuesday at home against the Yankees and could be up for an extended period if the outing goes well. The 25-year-old left-hander has lost his top-prospect status, but he's put up a decent 3.74 ERA and 47/15 K/BB ratio in 53 innings this season at the Triple-A level. There may be some value here for deep mixed-leaguers.
Mariners optioned RHP Mayckol Guaipe to Triple-A Tacoma.
Guaipe was only in the majors for a day. The right-handed reliever could get another shot later this summer.
Scott Kazmir (shoulder) has been cleared to return to the A's rotation Friday in Boston.
Kazmir made it through a 30-pitch bullpen session Sunday without issue and he said he felt "great" after a followup game of catch Tuesday. The left-hander had to make an early exit from his start last Wednesday against the Tigers after experiencing shoulder tightness, but an MRI taken last Thursday showed no major issues.
Edwin Encarnacion remains out of the Blue Jays' starting lineup for the second half of Tuesday's doubleheader against the Nationals.
Encarnacion didn't start the first game either, though he drew a walk as a pinch-hitter. There's nothing to be concerned about here. Toronto is just having to get creative in a National League park.
Ryan Zimmerman is not in the lineup for the second half of Tuesday's doubleheader against the Blue Jays.
Zimmerman went 0-for-3 with an RBI in the early game, a 2-0 win for Washington. He will be available off the bench as the Nationals try to sweep the twin-billing.
Rajai Davis is expected to rejoin the Tigers on Friday.
Davis was excused from the club on Tuesday afternoon so that he can be present for the birth of his second child.
Khris Davis underwent scheduled surgery Tuesday to repair a torn meniscus in his right knee.
Brewers assistant general manager Gord Ash said the surgery "went well" and guessed that Davis would only miss 4-6 weeks. Gerardo Parra will serve as the primary left fielder for Milwaukee until early-to-mid July.
