Pitching prospect Stewart exits as precaution

MINNEAPOLIS -- Top pitching prospect Kohl Stewart left his start early Tuesday night as a precaution, Twins general manager Terry Ryan said Wednesday.

Stewart, ranked as the No. 24 overall prospect by MLB.com, has been dealing with shoulder soreness and was topping out at 90 mph in his start with Class A Cedar Rapids on Tuesday. He left his outing after just 1 1/3 innings.

"I don't think it's serious," Ryan said. "He came out of the game, but I don't think it was serious."

Stewart, 19, has fared well in his first full professional season after being taken with the No. 4 overall pick in the 2013 First-Year Player Draft. The right-hander has posted a 2.59 ERA in 19 starts with 62 strikeouts and 24 walks in 87 innings.

Ryan said he remains hopeful Stewart will be able to return to action this season. "I hope so," Ryan said. "We still have season left. We've done a number of tests on him and haven't been able to find anything wrong."
