4 left-handed relievers who could replace Aaron Loup

Sean Doolittle

A name that most New York Mets fans surely recognize, another one of their more tempting options to replace Aaron Loup is the former Washington Nationals closer Sean Doolittle.

Starting out his career with the Oakland Athletics back in 2012, Doolittle spent the first 6 years of his career with the A's before being traded to the Nationals at the 2017 deadline.

He served as closer for the Nats from then thru the 2019 season, helping to lead them to the World Series in 2019, and remained in Washington as a set up man for the Covid-19 shortened 2020, however he did struggle over the 11 games he appeared in that year.

Following his time in Washington, Doolittle signed a 1 year contract with the Cincinnati Reds prior to the 2021 season, and was later picked up by the Seattle Mariners for the remainder of the year.

For his 10 year career, Sean Doolittle has appeared in 457 games with his 4 teams, logging a 3.23 ERA over 445.1 innings over that time, while locking down 112 saves.

While his 2021 numbers do not match the consistency he showed earlier in his career, Doolittle did show he can still be an effective hand out of the pen, as he logged a 4.53 ERA over 49.2 innings in 56 games between the Reds and Mariners.

While Doolittle's best days may now be behind him, he definitely showed in 2021 that he has something left in the tank, and with the Mets still looking to plug up their holes in the bullpen once the lockdown is over, he is certainly an option worth considering.
