Rockies purchased the contract of RHP Jon Gray from Triple-A Albuquerque.
Gray will make his major league debut on Tuesday night against the visiting Mariners after weeks of speculation that he was on the verge of a callup. The 23-year-old right-hander was sporting a 2.90 ERA and 82 strikeouts over his last 80 2/3 innings at Triple-A and could have value as a matchups-to-matchups play down the stretch. He's not a great fantasy bet in his debut against the M's at Coors Field.
Rockies optioned RHP Gonzalez Germen to Triple-A Albuquerque.
The move clears a roster spot for top pitching prospect Jon Gray, who will make his major league debut on Tuesday night. Germen has a 4.63 ERA in 11 2/3 innings (one start, seven relief appearances) this season for the Rockies.
Giants sent INF Joaquin Arias outright to Triple-A Fresno.
Arias was designated for assignment by the Giants on July 27 and passed through waivers unclaimed. The 30-year-old is a .265/.293/.350 career hitter in the majors.
Buck Farmer has been moved to the Tigers' bullpen.
Farmer allowed four runs -- three earned -- over just 4 1/3 innings of work last Friday against the Orioles and owns an 8.50 ERA in four total starts this season for the Tigers. Matt Boyd, acquired from the Blue Jays in last week's David Price trade, is going to get the next shot in the Detroit starting rotation.
An MRI taken Tuesday on Kyle Kendrick's right shoulder confirmed the initial diagnosis of inflammation.
That's obviously good news, though Kendrick will get a second opinion this week from Dr. David Altchek. The right-hander was placed on the disabled list August 1.
Justin Turner (thigh) expects to rejoin the Dodgers as soon as his 15-day disabled list stint is over.
Turner landed on the disabled list July 28 with a skin infection on his right thigh. He hasn't been cleared yet for baseball activities, but that should change soon.
Red Sox purchased the contract of RHP Henry Owens from Triple-A Pawtucket.
Owens will make his major league debut on Tuesday night against the rival Yankees. The 23-year-old right-hander had registered a 3.16 ERA, 1.14 WHIP and 103/56 K/BB ratio through 122 1/3 innings this season at Pawtucket and is worth a try in most mixed fantasy leagues. He was the No. 19 prospect on MLB.com's top 100 this winter.
Padres activated RHP Ian Kennedy from the paternity leave list.
Kennedy welcomed a daughter on Friday and didn't wind up missing a start in the Padres' rotation. The 30-year-old righty owns a 4.44 ERA, 1.29 WHIP, and 94/30 K/BB ratio in 103 1/3 innings this season for the Padres.
