tries to explain Tim Lincecum's early season struggles. He was pounded last night in Colorado for six runs and nine hits in 2.1 innings.
With his diminished velocity, Lincecum has also seen his peripherals drop. In his first full season, Lincecum struck out 28.6% of the batters he faced. That number dropped to 24.4% last year. That’s still pretty exceptional, but the number is declining. What’s more concerning is Lincecum’s walk rate. Lincecum’s BB% fell to a career low 7.5% in 2009, but it jumped to 9.6% last year. And even though he has lost velocity in the past and succeeded, you have to wonder how long he can be effective if his fastball averages 90 mph the whole season.
