The better question might be what WASN'T his problem yesterday. That pitch location plot tells the story as simply and as straightforward as any game recap could. He threw too many fastballs, 2 and 4-seam, up in the zone and then couldn't command his curveball near the zone. Nova didn't have 1 pitch working for him yesterday and when that's the case and you're missing up in the zone a lot, you're going to get punished.
The good news is that he didn't walk anybody yesterday, though I'm not sure that counts for much when you consider how many hits he gave up and the fact that he walked 5 in his first start. In 9.1 IP over these first 2 starts, Nova has put 23 men on base. 16 hits, 5 BB, and 2 HBP. That's way too many of all 3 of those categories and Nova needs to be better than that. He's had 2 starts with command issues. Time to see if he really has matured and can make the adjustment next time out to correct them.
