Wow Sferik. John Rickert's site is incredible. Left Handed Pitchers are typically slower to the plate since they can come to a full balance point and still either pick to first or throw to home plate. RHP need to slide or glide step to the plate. The goal for the RHP is to deliver a pitch to the plate with a runner on base in 1.3 seconds or less (from initial movement to glove of the catcher). A typical catcher with a pop time of 2.0 will be able to throw out runners with a pitcher who is 1.3 or less. The LHP can be as slow as they want as long as they have a great move. Many runners will "sit" on a LHP and wait until he goes (front hip slide) to the plate. Other runners will attempt to just guess and go on first movement. Nonetheless, LHP are typically slower to the plate with runners on first (some LHP will slide or glide step to the plate with runner on 2b). Joe Morgan is correct.
