Two days after starting in the Oakland A's 6-4 loss to the Seattle Mariners, Dan Straily was sent back to Triple-A Sacramento. Drew Pomeranz, who won a spot start for the A's on Wednesday in Game Two of a doubleheader, has been moved into the A's rotation in place of Straily. To replace Pomeranz in the A's bullpen, Oakland recalled left-handed reliever Joe Savery.
The A's also announced that reliever Ryan Cook is headed to the disabled list. Cook left Game One of the doubleheader with a forearm strain. The injury isn't expected to be serious and Cook could return at or near the 15-day mark. His DL stint is retroactive to Thursday, May 8. Replacing Cook in the A's bullpen is reliever Fernando Rodriguez, who will be making his Oakland A's debut more than a year after being acquired from the Houston Astros. Rodriguez missed all of last season after injuring his elbow during spring training and undergoing Tommy John surgery.
Straily returns to Sacramento with a 4.93 ERA in 38.1 innings over seven starts. His command hasn't been sharp this season, as he has issued 15 walks and he has allowed an MLB-high nine homeruns. He has been tough when he has hit his location, however. Straily has 34 strike-outs and batters are hitting just .232 against him with a .308 OBP. Hitters have a .486 SLG against him, however. Last season, Straily held opposing batters to a .233/.308/.358 line.
Pomeranz threw five shutout innings in the A's win on Wednesday. That was his first start for Oakland. In 18.2 innings as a starter and a reliever this season, Pomeranz has a 1.45 ERA and a 16:6 K:BB. He has allowed 13 hits, including two homeruns. Although Pomeranz was a reliever for Oakland until Wednesday, he has plenty of experience starting, having been a starter exclusively up until the final few weeks of last season.
Cook hits the DL for the second time this season. He began the year on the disabled list after experiencing shoulder soreness during spring training. In 12.1 innings this season, Cook has a 2.92 ERA and a 15:9 K:BB. He has allowed just six hits.
Rodriguez and Savery have both pitched well for Sacramento this season. Rodriguez joined the River Cats in early April on a rehab stint and was optioned to Sacramento in early May. With the River Cats, Rodriguez had an 0.73 ERA and an 11:4 K:BB in 12.1 innings. Rodriguez last pitched in the big leagues with Houston in 2012, when he posted a 5.37 ERA in 71 appearances for the Astros.
Savery, who was claimed off waivers by the A's from the Philadelphia Phillies this spring, had a 3.86 ERA in 11.2 innings for Sacramento. The former Phillies' first-round pick walked seven, but he struck-out 14 with the River Cats. He allowed two runs over his last 6.1 innings, with seven strike-outs and three walks. Savery appeared in 18 games in relief for the Phillies last season, posting a 3.15 ERA and a 14:11 K:BB in 20 innings.
