Detroit, MI (SportsNetwork.com) - The Detroit Tigers announced Tuesday that designated hitter Victor Martinez underwent successful medial menisectomy surgery on his left knee.

It's expected that Martinez will start rehab immediately and resume full baseball activities in 4-to-6 weeks.

"We are very happy the surgery went well and that Victor will be ready to compete for the start of the 2015 season," said Tigers president, CEO and general manager David Dombrowski.

Martinez tore his meniscus during an offseason workout. It was the second significant knee injury he has sustained working out in the offseason in his career. He missed the entire 2012 season due to an ACL tear suffered during January of that year.

The Tigers re-signed Martinez to a four-year, $68 million contract after an All-Star 2014 season that saw him set career highs with 32 home runs, a .335 batting average, .409 on-base percentage and .565 slugging percentage.

The surgery was performed by Dr. James Andrews in Pensacola, Florida.
