The SF Giants have cornered the market on ground ball pitchers, but that is not the only trait they seemingly covet with pitchers. Nearly all of their pitching additions this offseason have also demonstrated above-average extension.
Another trait that many of the SF Giants pitching additions share in common
Think of extension as the point in which the pitcher releases the ball. Taller pitchers typically generate above-average extension because when they release the ball, it is closer to the plate.
While that is a rule of thumb, that is not always the case. It would have been interesting to see what type of extension Tim Lincecum and his 5-foot-11 frame generated.
