says the Pitch F/X tool was Peavy’s fastball tonight (4/28):

Pitch Statistics (Velocity Histogram)

Pitch classifications provided by the Gameday Algorithm and may be inaccurate.
Clicking individual pitch types will provide individual velocity histograms for each pitch.

Nibbleness is the arithmetic mean of the distance of each pitch, in inches, from the edge of a normalized strikezone. Lower indicates “more Nibbley”.
Time to Plate is the time, in seconds, that it takes an average pitch of this type to reach the plate. This is strongly correlated with velocity, but also factors in movement.

UPDATE: Peavy:

”We talked about this being a process. Anyone that watched the game can see it coming together. It’s just frustrating when you can’t make a pitch in that first inning. It’s coming. I just found my mechanics of where I needed to throw it. The bottom line is I’m still searching, but it’s coming. The end result is not about finding it, though; it’s about winning games. You’re not paid to try and find your mechanics.”

Peavy’s velocity had picked up 2-3 mph on his last start compared to his first 3 starts but that didn’t last:
