The 25-year-old made an appearance in the All-Star Futures Game on July 12, after starting the season with a 1.08 ERA, 60 strikeouts and 11 walks in 75 innings (12 starts) for Double-A San Antonio. He was promoted to Triple-A El Paso in early July and had a 4.39 ERA in six starts there.
"It's been a pretty crazy season so far, being in Double-A, getting my feet wet there and then coming to Triple-A and now being here. It's been a great experience overall so far," Rea said.
Rea will have family and friends in attendance Tuesday at Petco Park to watch his debut.
