Brayan Bello Needs to Mix Speeds Better
Brayan Bello's changeup has always been his best pitch, and many, including Red Sox broadcaster Lou Merloni, believe it could be even more effective if he reduced its velocity further below his sinker's speed, which is his primary fastball. Currently, the pitches are too similar, with only 1.4 inches of horizontal movement difference. This makes it easy for hitters to adjust, as guessing one pitch but getting the other still puts them in a good position to hit.
Another problem for Bello has been his sinker, which is being hit at an alarming rate. Last season, opponents batted .278 against the pitch, which, while not ideal, is significantly better than the .344 average they are hitting this season.
Reducing the changeup's velocity could also benefit the sinker, making it appear faster to hitters and making it more challenging for them to adjust between the two pitches, which make up over 70% of Bello's repertoire.
Despite these struggles, there's a glimmer of hope: the expected statistics for Bello’s sinker are significantly better than the actual numbers, suggesting he has been unlucky so far in 2024.
Bello has also completely abandoned his four-seam fastball, a significant adjustment made by pitching coach Andrew Bailey across the staff. Although this pitch was Bello’s second-least used, and opponents hit .310 against it last year, it might be worth reintroducing to provide hitters with something different.
Finally, there is a need to adjust expectations for Bello.
