Why Cashman hasn't called up Dominguez

Dominguez has been one of the Yankees' best minor league pitchers this season

In 24 starts for Double-A Somerset, the 25-year-old right-hander has a 3.20 ERA, 1.02 WHIP and 141 strikeouts in 123 innings.

He's also held opponents to a .219 batting average and has shown excellent command of his fastball and changeup.

The Yankees have one of the best starting rotations in baseball, led by Gerrit Cole, Nestor Cortes and Luis Severino.

Domingo Germán, Jameson Taillon and Jordan Montgomery are also all capable starters, and Clarke Schmidt is expected to return from injury soon.

While Dominguez has been impressive in the minors, he still needs to make some adjustments before he's ready for the majors.

His command of his curveball needs to improve, and he also needs to be more consistent with his fastball location.

Cashman knows that Dominguez has the potential to be a major league starter, but he's not going to rush him to the majors.

He wants Dominguez to continue to develop in the minors and make sure he's ready for the challenges of the majors before he calls him up.

Dominguez is a talented pitcher with a bright future, but he's not yet ready for the majors.

Cashman is being patient with him and allowing him to develop at his own pace.

Once Dominguez is ready, he'll be a valuable addition to the Yankees' rotation.
