Starting shortstop Omar Vizquel will undergo knee surgery later this week and it will cause him to miss the next 4-5 weeks. The 41-year old switch hitter will miss the start of the 2008 season. Vizquel played in 145 games last season for the Giants and he was 126 for 513 (.246 avg, .621 OPS) with 54 runs scored, 4 homers, 51 RBIs and 14 stolen bases. The Giants can replace Vizquel’s bat but they will miss his glove which is often Golden despite his advancing age. 26 year old righty swinging Kevin Frandsen will likely take over as the starting shortstop until Vizquel is ready to return. He played in 109 games last season for the Giants and he was 71 for 264 (.269 avg, .710 OPS) with 26 runs scored, 5 homers and 31 RBIs.
