Arguably the greatest postseason pitching performance of all time, here is a look at Yoshinobu Yamamoto’s Stuff+ scores from the playoffs. He was as dominate as can be, posting 3 wins in the 7 game World Series. #Dodgers #MLB #WorldSeries #Yamamoto

Want to be a better PITCHER? You need a better PROCESS. ERA ❌ Wins/Losses ❌ K/9 ❌ The best pitchers in the world separate themselves through process metrics — measurable indicators of execution and consistency. The PROCESS METRICS that tell the full story. ⬇️⬇️⬇️

Trey Yesavage dominance. One of a kind performance from the rookie last night to give the Blue Jays a 3-2 series lead. His elite Splitter and Slider were on full display. #BlueJays #StuffPlus #MLB #WorldSeries

Will Klein brought out some serious Stuff last night! Going 4 scoreless all in extra innings, he was the difference maker for the Dodgers last night. Hope to see more Will Klein in the future. #WorldSeries #Pitching #Dodgers #MLB

The matchup: George Kirby vs. Shane Bieber. Season on the line, we have two great pitchers dueling it out on the mound. Each pitcher throws 4+ pitches at over a 12% clip, so we are going to see a lot of different stuff thrown tonight. #MLBPlayoffs #Mariners #BlueJays

Roki Sasaki is unbelievable! His Splitter looked unhittable last night, as he slammed the door for the Dodgers. Sasaki is going to continue to be a huge weapon as the Dodgers look to go back to back. #mlbplayoffs #RokiSasaki #Sasaki #Dodgers

I wanted to highlight someone new with some ridiculous Stuff. Aaron Ashby is gross. His high velocity and high spin curveball is a true unicorn. At almost -20 IVB, 84.5 mph is unheard of. #Stuff #Brewers #Ashby #MLBPlayoffs #NLCS

Bryce Miller with a series altering performance last night. He stepped up in a huge way for the Mariners, giving them a 1-0 lead over the Blue Jays. Oh, and his fastball is elite. 19 vert from a low slot at 96.2 mph. #Mariners #MLB #Playoffs #BryceMiller

Bad news for Cubs fan, Trevor Megill is opening today. If Megill can keep his pitch count down, and extend for a few innings it would be a game changer for the Brewers. Let’s see how it goes👀 #Brewers #MLB #Playoffs
