Rangers claimed INF Matt E. Duffy off waivers from the Astros, optioned to Triple-A Round Rock.
Duffy was designated for assignment earlier in the week by the Astros to make room on their roster for Yulieski Gurriel. The 27-year-old struggled in his limited time with the Astros but will provide nice organizational depth for the Rangers.
Mike Mayers will make his major league debut for the Cardinals on Sunday night against the Dodgers.
Many had hoped that it would be top prospect Alex Reyes getting the call for the spot start on Sunday, but it'll be the 24-year-old Mayers instead. He has pitched well between Double-A Springfield and Triple-A Memphis this season, compiling a 2.62 ERA, 1.21 WHIP and 86/36 K/BB ratio across 106 2/3 innings.
Dodgers optioned LHP Grant Dayton to Triple-A Oklahoma City.
The Dodgers needed a fresh arm in the bullpen after Friday's marathon game, so Dayton became the odd-man out. He pitched two scoreless innings of relief with a pair of strikeouts in his lone appearance with the big league club. Expect to see him back with the Dodgers soon.
Dodgers recalled RHP Ross Stripling from Triple-A Oklahoma City.
The 26-year-old right-hander has appeared in nine games for the Dodgers in 2016, compiling a 4.53 ERA, 1.36 WHIP and 34/18 K/BB ratio. He's expected to work in a long relief role for the Dodgers.
Mookie Betts (knee) is not in the Red Sox starting lineup on Saturday.
Betts was removed from Friday's game due to what has been termed as minor soreness in his right knee, but manager John Farrell wanted to be safe and give him an extra day to rest. Expect to see him back atop the lineup for Sunday's series finale.
Angels optioned C Juan Graterol to Triple-A Salt Lake.
The club wanted more experience behind the plate so they recalled the hot-hitting Carlos Perez from Triple-A on Saturday. Graterol will continue to serve as organizational catching depth for the Halos.
Angels recalled C Carlos Perez from Triple-A Salt Lake.
Perez was optioned to Triple-A earlier in the month when Geovany Soto returned from the disabled list, but is needed back due to the lack of catching depth. He was also stinging the ball at Triple-A, going 11-for-31 with five extra base hits since his demotion.
Diamondbacks placed INF Nick Ahmed on the 15-day disabled list with a right hip impingement.
Ahmed may have been expendable anyways with Chris Owings returning from the disabled list. He was hitting just .218/.265/.299 with a 58/15 K/BB ratio in 284 at-bats with the Diamondbacks before suffering the hip injury.
