Seattle Mariners Pitcher’s Put-Away Pitch One of the best in MLB, on a website – Sports Illustrated

The Seattle Mariners starting bullpen received heaps of praise during the 2024 regular season. And that hasn’t changed even though the team closes out the year on Sept. 29 against the Oakland Athletics.

The Mariners boasted the only rotation in the league in which four pitchers started 30 or more games. Seattle ace Logan Gilbert is in the 2024 All-Star Game. Gilbert’s teammates and fellow starters Luis Castillo and George Kirby are in the 2023 All-Star Game.

The only two members of the rotation not involved in the Midsummer Classic are Bryce Miller and Brian Wu, who both played their second major league season in 2024.

Both pitchers have made strong cases to be considered two of the best young pitchers in MLB. Woo finished the year with a 2.89 ERA and 101 strikeouts in 121.1 innings and 22 starts.

Miller had a 2.84 ERA with 171 strikeouts in 180.1 innings and 31 starts.

Underscoring the pair’s rise through the major league ranks is that Miller now has one of the deadliest pitches in baseball.

According to the popular advanced analytics website Baseball Savant, Miller had the highest rated splitter in all of MLB with a performance value of 10. Performance value is a score based on the impact a pitch has in an event. It takes into account factors such as runners on base, number of strikeouts and pitch counts at the plate.

The splitter is considered one of the best pitches in the league. The fact that Miller has had his best in just two years as a major leaguer is an incredible feat. Especially considering Gilbert has a dangerous splitter in his own right.

Popular content creator The Couch GM talked more about Miller’s splitter in a post on “X” (formerly known as Twitter).

The Couch GM (@The_Couch_GM on “X”) mentioned that Miller’s split toe is running, falling and cutting at the same time. This means that the pitch has three different movements depending on the release.

This detail was mentioned back on May 26th in an article published by MLB.com’s David Adler.

Adler mentioned the exact measurements of Miller’s splitter movement in the article:

“Miller’s splitter has an incredibly wide range of motion. It can move up to 16 inches. It can fall up to 50 inches. And it can even cut up to four inches.”

In the article, Miller said he doesn’t intentionally dictate what kind of movement the splitter will take.

“It just does that on its own,” Miller said in the article. “Sometimes it will be really deep and then sometimes it takes off. I don’t know.’

Miller could have an argument as the second-best starter in the Mariners’ rotation. At least on a 2024 basis.

And there’s room for him to get even better.

It will be interesting to see how Miller and the rest of the team fare in 2025 after an elite 2024.
