McKay added a cut fastball about a month and a half ago and it looks like many pitcher's sliders, breaking 12/5. The curve is what has him so high in the Draft because he has really good control of it and he throws it regardless of count.
Good season for UK; the Louisville fanbase has caught a craving for hosting Regionals and then Super Regionals, and you can see from the way the games were played this weekend why. One thing you cannot say about the games despite the incredible length (mostly due to how pitching changes are more abundant in elimination games) is that they are boring; mistakes are usually lethal and the tension level goes way up. I think a big difference this weekend was one part the experience of the last two Supers for Louisville, but the bigger was probably Louisville is truly constructed by McDonnell for Jim Patterson and by extension Omaha. Our outfield defense and our middle infield is tailor made for the surface and the dimensions, and our pitching staff pitches to it. There are a lot of hard hit balls in Jim Patterson that are outs; at Cliff Hagan a good number of them are doubles. It's not exactly the old Astrodome or Candlestick as far as difficulty to hit in, but you have to have a high quality centerfielder to cover that ground and Taylor is flanked by two with outstanding range in Lyman and Stowers.
