Sproat has some good outings, has good stuff at times, and then takes a step back with his command and has bad outings.
Look, he’s now going into the AS break with a 5.16 ERA. He’s a 5. He’s pitched like a 5 all season. Is it possible he becomes more? Sure, and it’s still possible that Joey Ortiz becomes an All-Star. The reality is that it’s far more likely that Sproat is just a 5 than he ever becomes Corbin Burnes.
We need to stop with that comparison because it’s just the highest of high end outcomes and few guys ever reach that point. The Brewer pitching lab, as good as they are, cannot just miracle any pitcher that they like with good stuff into an ace.
