New York Mets
Mazeika was drafted by the New York Mets in the eighth round of the 2015 Major League Baseball draft with the 239th pick overall. He started playing in the Mets organization in 2015 with the Kingsport Mets,batting .354 (3rd in the Appalachian League)/.452 (3rd)/.540 (7th) with 44 runs (6th),27 doubles (1st),48 RBIs (2nd),and 17 hit by pitch (1st). [8] He was named an Appalachian League Post-Season All-Star and an MiLB Organization All Star. [9] He was promoted to the Columbia Fireflies in 2016,played catcher,and batted .305/.414/.402.
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. He was named an FSL mid-season All Star and post-season All Star. [9] He played the next two seasons in Binghamton,and was named an Eastern League mid-season All Star in both 2018 and 2019, [9] before a brief period in 2019 playing for the Scottsdale Scorpions of the Arizona Fall League for 25 games.
Mazeika was called up to the majors for the first time on August 25,2020. [10] He was then demoted to the alternate training site on August 26. [11] Mazeika was called up for a second time on August 28, [12] but was demoted a second time on August 29.
On May 5,2021,Mazeika was recalled to the majors after Brandon Nimmo was placed on the injured list. [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. With the bases loaded,he hit into a fielder's choice,bringing Pete Alonso home from third base. It was his first walk-off RBI,as well as his first RBI in the MLB. The Mets won the game 5–4,completing a comeback from a 4–0 deficit. [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. [15] Although chronologically his first hit came on May 16,2021,when he hit a solo home run against the Tampa Bay Rays,he is actually credited with a double on April 11,2021 during a suspended game against the Marlins that was resumed on August 31,2021.

On August 18,2022,Mazeika was designated for assignment by the Mets. [17]
