Butler, who manages the Lancaster JetHawks of the California League, suffered chest pains and his hands and feet went cold while returning home on the team bus following the game against the High Desert Mavericks in Adelanto, Calif., the newspaper said. The bus changed course and headed to Antelope Valley Hospital in Lancaster, where the 48-year-old Butler was admitted for tests.
Jeff Lasky, the Jethawks' director of broadcasting and media relations, told the newspaper that doctors had ruled out a heart attack. Lancaster is the Arizona Diamondbacks' Single-A affiliate.
"He's getting tests done at the hospital to make sure everything checks out OK," Diamondbacks manager of minor league operations A.J. Hinch told the newspaper. "The doctors are real optimistic that everything is fine. He's resting comfortably and his family is with him. We're just waiting to hear what the doctors have to say."
Butler, an All-Star in 1991, had 2,375 hits and a .290 career batting average over 17 seasons with the Atlanta Braves, Cleveland Indians, San Francisco Giants, Los Angeles Dodgers and New York Mets. His 558 stolen bases rank 24th all-time.
Butler was diagnosed with throat cancer while playing for the Dodgers in May 1996, but returned four months later. He retired following the 1997 season.
