CHICAGO -- The Detroit Tigers placed designated hitter Victor Martinez on the 10-day disabled list Sunday with an irregular heartbeat.
He spent 12 days on the DL in June with a similar ailment.
Martinez played in both games this weekend against the White Sox, so it's not clear what prompted the heart problems. The Tigers and manager Brad Ausmus will speak to the media later this morning.
To replace Martinez on the 25-man roster, the Tigers recalled outfielder JaCoby Jones.
Jones was optioned to Triple-A Toledo before Saturday's game, so he has been gone only one day.
