Texas Rangers President Nolan Ryan is in a Houston hospital undergoing tests on his heart.

The Rangers said in a statement Monday the 64-year-old Ryan is ”resting comfortably and reports he is feeling better.” He is expected to be released from the hospital in a few days.

Ryan had a double-bypass operation in 2000 and has a family history of heart disease. He sought treatment after experiencing discomfort Sunday morning while at his home in Georgetown.

Ryan is a Hall of Famer who has the record for most no-hitters (seven) and strikeouts (5,714). He’s been running the Rangers since 2008 and became part-owner last summer, as Texas was on its way to the World Series for the first time.
