We've seen plenty of waiver wire arms pop up out of seemingly nowhere to have themselves a great outing and the latest to catch everyone's eye is Jesse Hahn who put up a dazzling 8.0 IP, 0 ER, 1 Hits, 2 BBs, 6 Ks against the Angels last night. I watched this outing and can see why some are excited - A lively Fastball with movement that induced a ton of groundball outs and a big hook that earned whiffs. Unfortunately, there are plenty of reasons that this just won't work. 1) I don't trust Hahn to live down in the zone for strikes nearly as much as last night...not to mention how often the Angels batters rolled over pitches that were well over the plate 2) He doesn't trust his Changeup and I doubt it will become a proper third pitch 3) This was the Angels who are Trout and little else and, maybe most importantly 4) There isn't room for him in the rotation. Sonny Gray is expected to return in the next two weeks or so and Kendall Graveman is nearly back. Mix that with Sean Manaea, Jharel Cotton, and Andrew Triggs, and you have a full rotation that doesn't include Hahn. It's possible Triggs theoretically gets the boot, but with the way he's performed outside of his last start I think he stays. All in all, Hahn just isn't a great investment to make and there might just be one more start left with his name on it that I don't love since he's not playing the Angels again.
Let’s see how every other SP did yesterday:
