Clutch Hitting? Nope, Clutch Pitching.
Looking over the RV and WV numbers in this morning's latest Friday Morning Figures, I happened on the last column for Pitching WV. Essentially EVERY pitcher currently on the 25-man roster has a positive WV (recall that WV reflects the score and inning of plays the pitcher is involved in, so the more close and late situations, the higher the WV for getting outs -- and lower for giving up bases). The only ones that don't are Armas and Tucker, but Tucker's numbers are from earlier this year and Armas is pretty close (-0.32). Overall, the Pitching WV is way positive.
The clutch hitting gets the headlines and the fireworks, but the pitching is winning the games.
