Well who knows, but what's been said in locker rooms and what's happening on the field are worlds apart.
You don't need killer stuff to win if you can hit your locations and change speeds. It's the absence of the great pitch that's making people think this is a fluke, but as Lenin once said, Quantity has a quality all its own.
Weaver has 9 pitches.
1 - changeup (82-84 MPH) usually low and away, sometimes high and away, occassionally inside to induce a foul or pop up.
2 - a fast changeup that's (87 MPH). I've seen him throw it a few times (always an outside corner) and it really throws off hitters timing, they think fastball, then slow the bat down thinking it's a change-up or vice versa (but it isn't either) He only throws this to non-power hitters.
3 - a 90 to 92 two seamer fastball (good lateral movement)
4 - a 90 to 92 four seamer fastball
5 - a 94 to 95 four seamer fastball that he rarely thows and usually throws high and inside, seems faster than the radar gun says because of his change up and looks like the regular fastball but it breaks less has more giddyup as it reaches the plate.
6 - 86ish slurve, with a 2 to 8 with a big break that he either throws high and drops it down for a strike or low and breaks down into the dirt.
7 - a 90ish slurve that has the same 2 to 8 break, but less break on it and looks like a fastball to the last second.
8 - a 86ish side-arm slider with a lot of 3 to 7 break on it that looks like a strike then breaks low and away.
9 - a 90 to 91 side arm fastball that doesn't dip so it almost looks like a rising fastball.
None in and of itself is an amazing pitch, but that he can locate all them is and feels confident to throw them at any count for a strike at any location makes it really hard on hitters because sitting one on pitch, your odds of seeing it are low even if it's a hitters count, and because it's not over the heart of the plate, you rarey get good wood on it even if you guess right. With a Verlander or a Liriano, as good as the are, you can sit on the fastball or the slider becuase you know it's coming, but with Jered, anything could be coming at any of the corners.
