Really absurd he didn't get up to Harrisburg this season. A grievous example of the Nationals confusing reluctance to call higher performers up.
Hes walking guys at nearly the same rate as he's giving up hits. 65 hits, 57 walks. So I get it. He was pushed to Wikmington last year and struggled mightily. They probably want to see him try to develop at a level where mistakes wont hurt as much.
In July he gave up 7 hits in 18 innings. But walked 11. Now in August he's getting smacked around with 24 hits in 16 innings(6 walks).
I know he'll hit 23 by the end of September but not everyone goes at the same rate. Maybe they want him going unto the off-season with some confidence. Hell be at AA next year no matter what. A handful of starts there now won't change much.
