HP Umpire Shane Livensparger ejected Reds 1B Joey Votto (strike two call; QOCN) at the end of the 1st inning of the #Reds-#Cardinals game. With one out and none on in the top of the 1st, Votto took a 1-1 sinker from Reds pitcher Miles Mikolas for a called second strike before striking out on a foul tip. Replays indicate the 1-1 pitch was located off the inner edge of home plate and thigh-high (px 0.99, pz 2.66), the call was incorrect.* At the time of the ejection, the Reds were leading, 1-0. The Cardinals ultimately won the contest, 4-3.

This is Shane Livensparger (43)'s 2nd ejection of 2023.

*UEFL Rule 6-2-b-1 (Kulpa Rule): |0| ≤ STRIKE < |.748| ≤ BORDERLINE ≤ |.914| < BALL.

This pitch was located 0.91 horizontal inches from being deemed correct.

This is the 239th ejection report of the 2023 MLB regular season.
