Detroit Tigers designated hitter Victor Martinez was released from the hospital Saturday after suffering from a rapid heartbeat, dizziness and cold sweats, manager Brad Ausmus told reporters Saturday.
"The thought process is probably a week of rest," Ausmus said.
Martinez, 38, first experienced the symptoms late in Thursday's game against the Tampa Bay Rays and was taken to the hospital. He underwent further testing Friday and stayed a second night in the hospital.
"I didn't find out about it until really, when he came out of the game because he was playing through it," Ausmus said on Friday. "My first thought was maybe dehydration. I'm not sure the doctors even know what caused it or what has caused it. Often times, the body corrects itself on its own."
Ausmus said Martinez will remain in the Detroit area for rest and further monitoring while the team begins a West Coast road trip starting Monday. During that time, Martinez will remain on the 10-day disabled list.
Martinez is batting .261/.337/.376 with five home runs in 60 games in his 15th big-league season. He's under contract with the Tigers through the end of the 2018 season.
To take Martinez's spot on the roster, the Tigers recalled catcher/first baseman John Hicks from Triple-A Toledo.
