Correa was held out of the lineup at Triple-A Fresno on Monday due to a sore right heel, Evan Drellich of the Houston Chronicle reports. GM Jeff Luhnow quickly dismissed any concern that Correa's injury was related to the fractured fibula he suffered last June, so for the moment, the Astros' top prospect just looks to be day-to-day. The 20-year-old hasn't been dominating Triple-A pitching since his May 11 promotion to Fresno (.241/.307/.430 batting line over 88 plate appearances), but if his numbers begin to improve upon his eventual return to the lineup, his big-league debut could arrive at some point this summer.
