Carlos Quentin will undergo another arthroscopic surgery on his right knee this offseason. The procedure should take place shortly after the season ends. Quentin had surgery on the knee back in March, but soreness has kept him from playing the field since September 19. The outfielder is expected to be 100 percent for spring training. "My training regimen, I'll change some of that, some of it will be weight loss, some of it will be rest," he said. "But it will all be geared toward staying on the field."
