39 is the magic number

Fascinating stuff from Joe Lemire of Sports Illustrated. Actually, it’s fascinating stuff from Orioles’ pitching coordinator Rick Peterson, which Lemire passes along: if you face more than 39 opposing hitters, you’re screwed. If you face fewer than 39, you’re probably going to win.

There is an easily intuitive element to this of course: duh, the more hitters a team faces, the more likely your team is to be giving up a lot of runs.  But that’s not the takeaway. The takeaway is how critical that 39th hitter is. How the odds of winning or losing shift so dramatically when that 39th batter comes to the plate.

Go read Lemire’s piece. It’s fascinating stuff. Baseball, because of it’s isolated data sets and stops in the action allow for all kinds of fascinating things like this to be studied. And every time I read about a new one, I love the sport even more.

A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.

Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.

Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
