Rea, 24, had been on the disabled list since May 18 with back spasms. He retired all 12 hitters he faced with five strikeouts. He threw 46 pitches with 32 going for strikes. The outing lowered Rea's earned run average to 1.29.
"My back feels fine and the rest of my body feels strong," said Rea. "I just wanted to feel right and have my mechanics feel good and have the rest of my body just kind of stay in control," said the 6-foot-5, 220-pounder who was the Padres 12th-round pick in the 2011 draft.
"I was really focusing on throwing strikes and getting ahead in the count. I was happy with the way the ball was coming out.
Right-hander Stephen Kohlscheen (1-0, 4.91 ERA) followed Rea and allowed a run on two hits with a strikeout over three innings to get the win for the 27-33 Missions. Right-hander Michael Dimock (2.25 ERA) had a strikeout in a perfect inning. Right-hander Tayron Guerrero (2.70 ERA) issued two walks with a strikeout in a hitless inning to get his fourth save.
Left fielder Alberth Martinez (.269) was 2-for-3 with two RBIs. Third baseman Duanel Jones (.333) had a double in four at-bats for a RBI and a run scored.
To activate Rea, the Missions released right-handed pitcher Luis De La Cruz.
The Padres added a minor league pitcher Saturday. They acquired left-hander Brad Wieck, 23, from the Mets to complete the spring training trade that sent left-handed reliever Alex Torres to the Mets. The Padres also got right-handed reliever Cory Mazzoni in the trade. Wieck will join low Single-A Fort Wayne.
In one other piece of pitching news, Padres left-hander Cory Luebke started for Single-A Lake Elsinore and worked a perfect inning (getting three ground outs) in his first outing on the mound since 2012. Luebke had "Tommy John" elbow reconstruction surgeries in 2012 and 2014. He threw 14 pitches with eight strikes.
