Former MLB reliever joins San Diego State baseball coaching staff

San Diego State has announced that longtime reliever Mark Melancon has joined the school’s baseball program as the pitching development coordinator. 

The 39-year-old Melancon hasn’t pitched since the 2022 season, so this new job implies that he has ended his playing career after 14 Major League seasons.

“It’s exciting to be part of a staff that has great experience and a clear vision on what needs to happen to be successful at the highest level. I’m eager to help these players compete for a national championship and hopefully move on to the next level,” Melancon said.

Assuming that Melancon is indeed hanging up his glove, he’ll finish his career with 262 saves and an excellent 2.94 ERA, over 726 2/3 innings in the majors. As opposed to most bullpen aces, Melancon didn’t bring heavy velocity or big strikeout numbers, instead relying on superb control and a knack for keeping the ball on the ground. 

Melancon had a 55.3% groundball rate over his career, the seventh-highest grounder rate of any pitcher in baseball (minimum 700 innings) within the 2009-22 timeframe.

Selected by the Yankees in the ninth round of the 2006 draft, Melancon ended up pitching for nine different clubs at the MLB level after he made his debut in the Show in 2009. The travels started early, as Melancon changed uniforms via three trades in as many years — from the Yankees to the Astros at the 2010 trade deadline, from Houston to Boston in December 2011, and then from Boston to Pittsburgh in December 2012. 

Though Melancon had seemingly broken out with a nice 2011 season, the rebuilding Astros still dealt him, and he then struggled through a rough season with the Red Sox.

The move to Pittsburgh brought both some stability for Melancon, and set the stage for the best stretch of his career. Melancon become a dominant set-up man and then closer over his three-plus seasons with the Pirates, delivering a sterling 1.80 ERA and 130 saves over 260 1/3 innings in a Bucs uniform. The right-hander was named to three All-Star teams during this stretch, and finished eighth in NL Cy Young Award voting in 2015 after posting a league-best 51 saves.

Free agency loomed for Melancon after the 2016 season, however, and the Pirates weren’t going to pay top dollar for a star closer. The result was yet another trade, as Melancon was dealt to the Nationals at the 2016 trade deadline, and he continued to pitch well for Washington throughout the rest of the regular season and into the playoffs.

The big free agent payday then came that winter when Melancon inked a four-year, $62M deal with the Giants, which briefly stood as the biggest contract ever given to a relief pitcher. While Melancon had a respectable 3.67 ERA over 115 1/3 innings with San Francisco, it wasn’t the kind of elite performance that was expected from the hefty contract, and injuries also hampered Melancon’s effectiveness.

As the Giants entered a partial rebuild and looked to cut payroll, Melancon was moved to the Braves at the 2019 trade deadline, and had an uptick in results (2.78 ERA in 22 2/3 IP) during the shortened 2020 season. A one-year, $3M deal with the Padres followed that offseason, and Melancon enjoyed one final All-Star campaign by posting a 2.23 ERA and 39 saves for San Diego. 

This led to a two-year, $14M contract with the Diamondbacks in December 2021, but Melancon struggled in 2022 and then missed all of 2023 due to a shoulder strain.

We at MLB Trade Rumors congratulate Melancon on a terrific playing career, and we wish him the best as he moves into the collegiate coaching ranks.
