Ken Griffey Jr. will have surgery on his left knee and right hamstring Monday, presumably ending a stellar comeback season for the oft-injured Cincinnati Reds star. The 35-year-old center fielder is expected to be ready for spring training. He will have arthroscopic surgery to clean out his left knee and treat scar tissue around his hamstring. The hamstring injury threatened his career last season. Griffey missed his 15th straight game Wednesday night because of a sprained right foot. He is batting .301 with 35 home runs and 92 RBIs in 128 games. Griffey is tied with Mickey Mantle for 12th on the career home run list with 536. Griffey hurt his foot rounding second base in early September in a game against Atlanta. At the time, the Reds said they thought he'd be able to play again this year.
