Joe Inglett played in 102 games for the Milwaukee Brewers in 2010, hitting .254/.331/.401 over the course of the season. He largely served as a pinch hitter for the Crew, but also played some corner outfield and second base. Overall, it was a rather nondescript season for a journeyman utility player.
That is, other than July 28, 2010.
On that day, Joe Inglett saw his first action as a major league pitcher. He tossed a scoreless inning of relief for the Brewers against the Cincinnati Reds. It was a 12-4 blowout in favor of the Reds in the top of the ninth inning. The Brewers simply needed an arm to soak up an inning of work.
What the Brewers didn’t know, however, was that they were unleashing a beast on the Cincinnati Reds. Joe Inglett’s mid-50s knuckleball.
Inglett struck out no one and walked no one in his one-inning masterpiece. As you can clearly see in the video, the Reds’ hitters simply could not wait back long enough to make quality contact on his pitches and still put them into the field of play. All-Star second baseman Brandon Phillips was almost left flailing at the plate against the Brewers’ right-hander.
Since the 2000 season, according to the Pitch f/x database, Joe Inglett is the only player to have thrown 100% knuckleballs while on the mound.
In terms of pure enjoyment, it beats the one inning Michael Cuddyer threw for the Minnesota Twins in 2011, in which he threw four different pitches — fastball, cutter, changeup, slider — in the mid-80s range and also tossed a scoreless inning in relief.
