Jeffrey Charles Pierce (born June 7, 1969) is an American former middle relief pitcher in Major League Baseball who played briefly for the Boston Red Sox during the 1995 season.

[14] After not being selected in the 1991 Major League Baseball draft, Pierce signed as a free agent with the Chicago White Sox on June 10, 1991.

Despite missing two weeks in the summer due to a rib cage injury, he was third in the Southern League in saves by the end of July.

[21] The Reds kept him in the Southern League with the Chattanooga Lookouts where he served primarily as a setup man for closer Chris Bushing, a transition he told the Birmingham Post-Herald he found "pretty frustrating.

"[14] Prior to the 1994 season, in the words of The Cincinnati Enquirer, Pierce was among a group of "young, no-name pitchers" invited to Major League spring training by the Reds.

General Manager Dan Duquette told the press that he expected Pierce to have a middle relief role in the majors in 1995.

[35] He made his Major League debut on Opening Day, April 26, 1995;[21] Pierce contributed to a two-hit shutout of the Minnesota Twins, pitching a scoreless eighth inning in the game at Fenway Park.

[37] Around this time, Dan Shaughnessy wrote in The Boston Globe of the struggling Red Sox bullpen, "On your scorecard they are known as Ken Ryan, Tim VanEgmond [sic], Jeff Pierce, Stan Belinda, Alejandro Pena and Derek Lilliquist, but their real names are famine, pestilence, death, destruction, Steve Crawford and Wes Gardner.

[21] A few days later, he and Ron Mahay were demoted to the minors to make room on the roster for Tim Wakefield, Tuffy Rhodes and Steve Rodriguez.

[46] In only fifteen innings in Taiwan, Pierce allowed eleven earned runs, leaving him with the worst ERA on the team at the end of the season.

[47] On June 20, 1997, the Chicago Cubs signed Pierce and assigned him to the Double-A Orlando Rays to replace pitcher Lee Hancock.

"[45] However, the Cubs released Pierce less than a month later after having traded Frank Castillo to the Colorado Rockies for pitcher Matt Pool.

Orlando Rays manager Dave Trembley said the organization decided to give his roster spot to Pool because he was the younger player.

He planned to finish his bachelor's degree, pursue a Master of Education, become a college baseball coach and live a "normal life.
