San Diego Padres outfielder Carlos Quentin will undergo arthroscopic knee surgery on Monday, according to the Associated Press. He will be out for 4-6 weeks.
The 29-year-old Quentin began to feel inflammation in his right knee shortly after he reported to spring training last month. The Padres' medical staff has been monitoring Quentin ever since, and the team now believes he will have to miss at least the first two weeks of the regular season.
The Padres traded two minor league pitchers to acquire Quentin from the Chicago White Sox on New Year's Eve. They plan to make him their cleanup hitter for the 2012 season.
Quentin is a two-time American League All-Star. In six major league seasons, he has hit .252 with 121 home runs.
