Walker was selected in the 37th round of the 2017 draft by the New York Mets. The left-handed reliever spent the majority of his career there, posting a 4.91 ERA and a 2.89 FIP in 22 innings pitched with the team in 2022. Walker started the 2023 season with the Triple-A Syracuse Mets, where he had a 1.84 ERA and a 2.82 FIP in 29.1 innings pitched. His success gave him his first taste of big league action that season, as he had an 8.10 ERA and a 5.26 FIP in 10 innings pitched.
The 2024 season saw Walker split time between the big leagues and Triple-A. In 12.1 innings with the Mets, he had a 5.11 ERA and a 3.90 FIP, with a 20 K% and a 10.9 BB%. With the Mets’ Triple-A team, he had a 2.83 ERA and a 4.15 FIP in 28.2 innings pitched with a 31 K% and a 16.7 BB%, while he struggled with the Pittsburgh Pirates’ Triple-A team after being traded to them.
Despite his struggles in the big leagues, <a href="https://www.fangraphs.com/players/josh-walker/23617/stats?position=P">Fangraphs’ projections</a> are rather high on the left-handed pitcher. Walker is projected to have a 3.84 ERA and a 4.07 FIP in 42 innings pitched, with a 23.9 K% and a 9.9 BB% by Steamer. The worst projection he received was from ATC, who projects Walker will have a 3.96 ERA and a 4.25 FIP in 28 innings pitched with a 23.4 K% and an 11.1 BB% in 2025.
The Blue Jays have done a good job rebuilding their bullpen, but a glaring issue is their lack of a high-leverage left-handed pitcher. As of right now, Brendon Little and Walker are the two left-handed relief pitchers on the 40-man roster, and while Walker is projected to do well and has options, it’s an area of focus for the Jays.
