I'm going to throw some pretty ridiculous stats your way about Luis Perdomo after his startling 6.0 IP, 3 ER, 5 Hits, 0 BBs, 9 Ks start tonight against the Brewers: He's holding a 70.5% groundball rate (1st in majors), with a .292 FIP and 2.90 xFIP, backed up by a 8.91 K/9 and a 2.62 BB/9. I'm sure you see his 4.19 ERA and shy away, but that FIP/xFIP can be real given his horrible 65.6% LOB rate and .344 BABIP. Entering tonight's game, he had allowed just 20.7% hard contact. If you're not familiar with Perdomo, he hurls heavy 94.6mph Two-Seamers and bumped his Curveball rate from 23.6% to 34.8% this season at the cost of his Changeup and for good reason: he's getting plenty more whiffs with the deuce, raising its whiff rate from 15.3% to 22.6%. The whole package makes out an arm you need to chase in a 12-teamer and while I prefer Wood and Karns (Perdomo doesn't have a third pitch making me question how deep he can go in games as he holds an IPS under 6.0), I would want to see if Perdomo can perform to his FIP/xFIP and keep the same K/BB numbers. There's plenty of value to be had here and I have to say, it's fun watching Trevor Cahill and Perdomo fight to earn the MFRSDPSPA.
Let’s see how every other SP did yesterday:
