He was pretty darn good in that one postseason relief appearance --- 3 IP, 0 hits, 0 runs, 6 ks --- https://www.baseball-reference.com/boxes/LAN/LAN201810160.shtml He was. But that doesn't change the fact that his relief experience is an extremely small sample. I almost wonder if that was a piggyback situation where he knew he was pitching, though, too. Given his propensity to be bad in the 1st inning in his starts, I wouldn't trust him in a relief role. That said ... I don't trust anyone right now, so who knows? I've heard this a lot of times about pitchers but don't really know if having first inning problems as a starter necessarily relates to them having it as a reliever. They really are two different things from the mental side of things.
