Shohei's breaking ball didn't look terrible, some spots could have been called strikes on the breaking ball, his fastball was off but his velocity did start to improve (91-92 but was hitting 94-95 before he got yanked), although his control on the FB never improved. I don't think he threw a single splitter (Maybe he threw 1?) so basically what we saw was a pitcher who looked like he was in his 2nd or 3rd Spring Training start.
So in conclusion there is no conclusion.
