Padres OF Quentin to have knee surgery

San Diego Padres outfielder Carlos Quentin has opted to have surgery on his right knee and will miss the remainder of the season.

Quentin, who is on the 15-day disabled list, has not played since July 30. It's been a struggle for Quentin this season as he has been dealing with injuries to his shoulder, wrist and both of his knees.

He was also on the paternity list for the birth of his son and served an eight-game suspension in April for charging the mound against the Dodgers' Zack Greinke.

Quentin, who turned 31 Wednesday, was hitting .275 with 13 home runs and 44 RBI in 82 games.
