Jeff Zimmerman of Fan Graphs crunched the numbers on the umpiring crew assigned to the World Series, using Pitch-F/X data along with strikeout and walk rates to rank the six umpires from most pitcher-friendly to most hitter-friendly:
Hirschbeck, who in addition to being pitcher-friendly is also the crew chief, will be calling balls and strikes in Game 1 and, if the series goes the distance, Game 7 as well.
Zimmerman delved even deeper into the data, breaking out “heat maps” for each umpire’s strike zone for right-handed hitters and left-handed hitters. The whole thing is definitely worth checking out, but I’ll quote this one bit of analysis: “At least none of these umpires are at the extreme ends of the strike zone spectrum. Compared to the previous playoff series … this crew’s strike zone should be one of the more consistent ones.”
Pirates right-hander Joe Musgrove is done for the year after suffering an abdominal wall muscle strain and stress reaction in his pelvic bone. While he isn’t expected to undergo surgery or miss additional time in 2019, he’s been prescribed six weeks of rest before resuming any baseball-related activities.
Musgrove, 25, finished out his third year in Pittsburgh with a 6-9 record in 19 starts, backed by a 4.06 ERA, 1.8 BB/9, and 7.8 SO/9. Despite logging a career-high 115 1/3 innings at the major league level, he’s also been dogged by a string of injuries, from the shoulder strain that robbed him of eight weeks at the start of the season to an index finger infection that kept him sidelined for a minimum 10-day stay on the disabled list in June.
While he works his way back up to full strength yet again, rookie right-hander Nick Kingham is expected to cover for him and will make a spot start during the Pirates’ series finale against the Brewers on Sunday. The 26-year-old righty hasn’t started a single game for the team since August 1, and currently carries a 4.69 ERA, 2.7 BB/9, and 8.1 SO/9 over 71 innings out of the rotation and bullpen.
