DETROIT -

The Detroit Tigers and former closer Jose Valverde have agreed to terms on a minor-league contract.

Tigers general manager Dave Dombrowski made the announcement before Thursday's game at Minnesota.

Valverde is a three-time All Star who led the AL with 49 saves in 2011 but wasn't as effective in 2012. He struggled badly in the postseason, allowing 11 hits, nine runs and two homers over four appearances, recording only eight outs. The 35-year-old became a free agent and wasn't re-signed.

Valverde will report to Detroit's spring training facility in Lakeland, Fla., for some work before being assigned to Triple-A Toledo. Dombrowski said there's no timetable or certainty for Valverde to join the Tigers.

The team tweeted the news Thursday afternoon.

Detroit has started the 2013 season with a closer-by-committee setup.
