Astros left-hander Dallas Keuchel came into this season as a 26-year-old with a lifetime 9-18 record and 5.20 ERA in 239 innings. He also had a 4.69 ERA in 134 innings at Triple-A. There was really no reason to believe he possessed any sort of upside beyond being a back-of-the-rotation starter on a really bad team.
And yet right now he’s 5-2 with a 2.92 ERA and 55/12 K/BB ratio in 62 innings for the Astros, who’re 6-3 when he starts and 11-25 when anyone else takes the mound. Last night he took a shutout into the ninth inning versus the Angels and came up one out short of a complete game.
There’s nothing different about Keuchel’s raw stuff this season–his average fastball is still under 90 miles per hour. But for whatever reason that pitch has gone from being something hitters tee off on to an actual weapon and his changeup has also gotten significantly better results.
Compared to his first two seasons in the majors Keuchel’s strikeouts are up 31 percent, his walks are down 47 percent, and he’s allowed just four homers in 242 plate appearances. I’m not sure how long this can last, but it’s been fun to watch and it’s kept the Astros from really being a mess this season.
