The final #s look bad, but he just ran out of gas in the 6th. Up untiil the 5th, he looked great. No walks, scattered some singles, gave up 1 run, that was it. Then in the sixth, he was out of gas and the Dodgers strung singles together and he didn't have any gas in the tank for his high 90s fastball anymore.
The three things that most impressed me. (1) No walks. (2) he's a pitcher not a thrower, he seemed to save his best stuff for the big hiiters or when somebody was on, and was looking for cheap outs from his defense for the weaker hitters. That was costing him a single or two, but it didn't hurt him really till the 6th. (3) Changed speed reall well.... From 97 to low 80s. Until the 6th when his fastball slowed.
My concern... He ran out of gas suddenly in the 6th, around the 100th pitch. Maybe jis young age has something to do with this. But that seemed to be his only problem. Makes me think he need to work on his leg strength, because it's the legs more than the arm that give out on a starting pitcher.
But for the first 5 innings, you'd never believe he was only 20.
