Jeremy Philip Hazelbaker (born August 14, 1987) is an American former professional baseball outfielder.

Hazelbaker was selected by the Boston Red Sox in the fourth round of the 2009 MLB Draft out of Ball State University.

He was named PCL Player of the Week on July 13, 2015, after leading the league in total bases, extra-base hits, and RBI.

[5] On March 31, 2016, the Cardinals announced Hazelbaker had made the major league roster; he played primarily as a backup outfielder and pinch hitter.

Playing against the Atlanta Braves, he, Aledmys Díaz, and Greg Garcia established a new MLB record by each hitting a pinch-hit home run, becoming the first trio to hit three pinch-hit home runs in one game for the same team.

[8] That home run also gave him two in his first four career games, joining Joe Cunningham (1954) as the only Cardinals to accomplish the feat.

[12] During a game against the New Orleans Zephyrs on June 28, Hazelbaker was instantly ejected when he charged the mound for José Ureña, who had nearly hit him in the head.

[13] After playing 13 games for Memphis and batting .325 with one home run and 11 RBI, St. Louis recalled Hazelbaker on July 19, 2016.

[15] On April 10, 2018, Hazelbaker was claimed off waivers by the Tampa Bay Rays and optioned to the Triple-A Durham Bulls.

[19] On July 28, 2019, Hazelbaker signed with the Sioux City Explorers of the independent American Association.
