Rejoice fellow prospectors for Michael Wacha has been slayed and disposed of on the DL with a shoulder injury. Good riddance Wacha, may the rookie nookieing begin. In the immediate aftermath Cards top prospect and K aficionado extraordinaire Alex Reyes was promoted. The early assumption was he’d fill Wacha’s roster spot. That was until he wasn’t. Shortly there after, it broke that he would be used out of the pen rather than take Wacha’s spot. Then Luke Weaver was called up. This made me excited, one because I’m nutty about prospects, two because I own Weaver in a whole shizz ton of leagues, and three because he fits the profile of the rookie starters that have been successful so far this season. What’s that profile Ralph? Control, command, and low walk rates. It’s the love, peace, and chicken grease of pitcher prospecting. Think about it Taillon, Maeda, and most recently Musgrove; the players letting up the least amount of free passes are having the greatest initial success out of the gate. It’s not a coincidence, because talented major league hitters will sit on junk pitches all day, and force you to throw strikes. That’s what Luke Weaver does Gentlemen and five ladies. He throws strikes…. lots of’em. He had 12 total walks in 83 innings at AA and AAA this season. He’s not some Phil Hughes boring control artist either, he brings with him a 10.0 K/9. Weaver keeps the ball in the ballpark too. In fact, he’s only allowed 7 homers across 197 minor league innings. All this to say you should pick him up. Whether you start him on Saturday vs the Cubs is up to your discretion, but there will be other matchups, better matchups. You’ll want him for those.
