jacksonianmarch might be trolling, but he certainly has a point. You can't ignore his last outing. it's not definitive, but is worrisome, especially if the Yankees are in the ALDS.
Also, it's not just the one game. He was great in July, went on the DL, came back, and has been up and down since then. He has not pitched more than 5 innings since July 27. Since going on the DL in July-August (2 weeks), he has pitched in 5 games. He was super in the first one on August 12: 5 inning, 12 K's, 1 hit, 0 runs, and 68 pitches. But since then, 1 inning, 3 inngs, 3.1 innings (2 earned runs), and 4.2 innings (3 earned runs vs. Orioles and 92 pitches).
Then there's the whole issue of earlier seasons, especially 2017, running out of gas in September/Oct.
