He's only had 4 starts since then, and is obviously being very pitch count limited. no runs in just under 4IP in Seattle, 3 runs in an error-filled 4 innings against the Cubs, the 1.1 IP debacle in Cincy full of walks and blooper singles, and the 4 IP start in Chicago when he gave up 3 runs on 1 hit due to walks. When he's giving up hits, it's not like they're HR or hard contact - he's just walking too many guys and it's obvious his schedule post IL stint hasn't allowed him to get into any rhythm. Kind of an unintended consequence of this innings - limit approach is his workload is so uneven it's really hard for Miz to find consistency.
When he throws strikes and is aggressive in the zone, he's going to mow through 5-6 IP in 80 pitches - but when he's not you can cut the innings pitched in half and it's a tax on the bullpen. He is basically at his IP amount from last season right now, so it's tough to see the Brewers pushing him extra hard the next few weeks if they have any intent of using him in the postseason. But, the trouble is if you don't pitch him now, you can't just dust him off in October for a playoff start or long reliever role with that amount of downtime. If he's healthy, you pitch him.
