Patrick Alan Mazeika (born October 14, 1993) is an American professional baseball catcher who is a free agent.

[1] In 2013, playing first base as a freshman, he batted .382(2nd in the Atlantic Sun Conference)/.489(1st)/.495 for Stetson, with 32 walks (10th) and 14 hit by pitch (3rd).

Mazeika then split time during the 2017 season with the St. Lucie Mets in the FSL and, later, the Binghamton Rumble Ponies, batting a combined .290/.389/.416.

[13] Mazeika made his MLB debut that day as a pinch hitter for Miguel Castro, grounding out to St. Louis Cardinals first baseman Paul Goldschmidt in his only at-bat.

On May 7, 2021, in only his second at bat in the big leagues, Mazeika was the hero in the bottom of the 10th inning during a game against the Arizona Diamondbacks.

[14] Then on May 11, during an interleague game against the Baltimore Orioles, Mazeika, in his fourth Major League plate appearance, was the hero again.

He had another walk-off fielder's choice ground ball in the bottom of the 9th inning that drove Jonathan Villar in to score, allowing the Mets to prevail 3–2, and becoming the first player since RBI became an official statistic in 1920 to have multiple walk-off RBI within his first four career games.

[20] On December 13, 2022, Mazeika signed a minor league contract with the Los Angeles Dodgers.

[21] He played in 52 games for the Triple–A Oklahoma City Dodgers, hitting .214 with one home run and 17 RBI.

On July 5, 2024, Mazeika's contract was purchased by the Diablos Rojos del México of the Mexican League.
