Just the facts ma'am. The trend is that Tim Lincecum's velocity on his fastball is headed downward, but it's not that bad. However, Lincecum is throwing a lot less fastballs than his other pitches. Besides velocity, his fastball's movement has tailed off in 2010. Could it be that all of this is in his head? What do you guys think after looking at this information?
