One day after exiting the third game of his rehab assignment for precautionary reasons with discomfort in his left quad, Astros rookie sensation George Springer was back at Minute Maid Park. He received treatment on his left quad muscle Friday and will be reevaluated further Saturday to determine whether he’ll be activated from the 15-day disabled list.

“He’ll come out (Saturday) and go through a complete workday and we’ll make an assessment after he goes through that workday whether or not we’re going to activate him or not,” manager Bo Porter said.

Springer checked back in with athletic trainer Nate Lucero on Friday after his three-game rehab assignment with Class A Quad Cities.

“I felt good. It just got tight on me,” Springer said. “That happens. I’m going to go see Nate and then see what they say.”

Springer has been on the disabled list since July 20.

“It’s extremely frustrating,” he said. “I want to be out there. I got a chance to watch every game. It’s extremely frustrating. … That’s the hard part. You want to be out there and you want to help the team and just be out there and play. When you can’t it’s tough.”

Although he commends his energetic rookie for “playing the game the right way,” Porter predicts that Springer will have to adjust to protect his tender quad.
