It's just two starts, but they're rather encouraging. I would leave him there to dominate and build up his pitch count. If he's still flat out dominating after five or so more starts, I bump him to Triple-A. Honestly, though, I don't know if it matters in AAA or AA. As long as he's pitching well and showing improved command, the main thing is for him to be on track for a summer call up to the Birds next year.
I don't see how this is a surprise. He didn't exactly dominate in 2019. He had a hot stretch in Aberdeen.
2020 doesn't mean anything to me. I know the reports out of the alternate site were glowing and people were raving about him but I don't see how facing the same pitchers over and over again is a telling sign of future success. No one can convince me otherwise.
This is essentially the best competition he's ever had to face. I'm not surprised that he's striking out this much...or that he's struggling so far. Hopefully he just needs to get his feet wet a little bit and get a bit more comfortable and we'll be able to laugh about that time we freaked out that AR had a slow start in the minors.
