ANAHEIM -- Rangers president Nolan Ryan was in a Houston hospital on Monday resting and undergoing tests after experiencing chest discomfort on Sunday morning at his home in Georgetown, Texas.
An initial statement issued by the club said Ryan is believed to have experienced a recurrence of a previous heart condition. Later, the club sent out another release that said test results indicated no new developments with the condition.
The club said Ryan will continue to be treated with medication and that he is expected to be released from the hospital in a day or two. His situation is not considered critical.
The 64-year-old Hall of Famer underwent a double heart bypass in 2000. He did not have a heart attack but was diagnosed with severe blockage in his left main coronary artery.
The club's first statement said Ryan was "resting comfortably." Rangers officials declined further comment.
Ryan was supposed to be in Anaheim on Tuesday night as part of pregame ceremonies honoring the late Gene Autry at Angel Stadium. He will not be able to attend.
Autry was the first owner of the Angels and is being inducted into the club's Hall of Fame. Ryan is already a member of the Angels Hall of Fame. He was scheduled to receive his Angels Hall of Fame ring and throw out the first pitch.
Ryan was also not planning to be in Cooperstown, N.Y., this week for the National Baseball Hall of Fame induction ceremonies. Ryan, who is baseball's all-time leader in strikeouts and no-hitters, was inducted into the Hall of Fame in 1999.
Ryan was named Rangers club president in 2008 by then-owner Tom Hicks. He was part of a group led by Bob Simpson and Ray Davis that bought the team last August and he added the title of chief executive officer during Spring Training.
He remains active as club president, watching almost every home game from his front-row seat next to the dugout and representing the Rangers at most public events. He was a part of the Rangers' group that attended the funeral of Brownwood firefighter Shannon Stone last week.
