Casey Mize Tosses Another Gem

If there’s a consistent theme with Casey Mize right now, it’s repeatability. His scoreless outing at Fenway Park fits cleanly alongside his previous two starts, giving him a run of three straight quality starts where the underlying data matches the results, keeping the Tigers in the game despite the 1-0 loss in extra innings.

Against Boston, Mize worked six-plus innings without allowing a run, striking out seven while giving up just three hits. He stayed in control throughout, finishing with a 62% strike rate and getting ahead early with a 65% first-pitch strike rate. It wasn’t overpowering in a traditional sense, but it was efficient and steady—something that’s becoming typical for him this year.

Fastball Usage and Early Count Control

Mize’s four-seam fastball led the way again, accounting for 44% of his pitches at 94.0 mph—about a tick above his season average. He used it to establish counts, particularly early, and generated a 34% called strike plus whiff rate. While there were a couple of hard-hit balls, the overall damage was limited, and he kept hitters from getting extended stretches of quality contact.

That approach mirrors his previous two starts, where he also leaned on the fastball early to set up his secondary pitches rather than relying on it as a put-away option.

Splitter Remains the Separator

The splitter continues to be his most reliable swing-and-miss pitch. Thrown 33% of the time, it produced a 30% whiff rate and drew swings outside the zone at a 60% clip. Hitters haven’t been able to square it up consistently, and that’s been true across all three outings in this stretch.

In each of his last two starts prior to Boston, the splitter played a similar role—used both as a chase pitch and as a way to finish at-bats once he got ahead. The consistency of its movement and location has been a key factor in limiting extra-base damage.

Slider Usage Rounds Out the Mix

Mize’s slider was used less frequently (14%) but was effective when called upon, generating a 62% called strike plus whiff rate. It helped him steal strikes and avoid predictable sequencing, especially against left-handed hitters.
