Ranking the available free agent lefty relievers for Pirates after 2024 season

The Pittsburgh Pirates’ bullpen was one of the biggest reasons why the team fell apart in the second half of the 2024 season. When the Pirates entered Spring Training, they were projected to have one of the best pens among all 30 teams. But Dauri Moreta underwent Tommy John surgery before the start of the season, and the Pirates lost Ryan Borucki for most of the year. David Bednar wasn’t his normal self, and Colin Holderman fell apart in August.

There were some bright spots, like Carmen Mlodzinski, Dennis Santana, and Kyle Nicolas, but ultimately, the bullpen was a huge letdown for the 2024 Pirates. Heading into this off-season, they need to revamp the reliever depth, especially with their left-handed pitchers. Unless the Pirates move Bailey Falter to the pen, then Joey Wentz is their only lefty reliever as of right now. So, based on who is on the free agent market, who would make the best possible fit?

Ranking the available free agent lefty relievers for Pirates after 2024 season

Tim Hill

Tim Hill feels like a pitcher from a completely different generation. The submarine southpaw isn’t like most relievers in today’s game, who are known for their high strikeout rates and overpowering stuff. Hill, instead, employs a low-90s sinker to induce weak contact at an insane rate while rarely striking batters out.

Last season, Hill pitched 67 innings for the Chicago White Sox and New York Yankees, working to the tune of a 3.36 ERA, 3.57 FIP, and 1.43 WHIP. He only walked 6.5% of opponents but had a K% of 10.7% and K/9 of 4.16. Hill is the first relief pitcher since Brandon Kintzler in 2017 to have a K/9 rate below 5.0 but have an ERA+ above 120 in at least 60 IP.

Hill induced ground balls at an insane 68.2% clip. Opponents had a -6.8-degree launch angle against Hill. That is the 24th-highest ground ball rate since batted ball data started being tracked (min. 60 IP). His 1.7% barrel rate is also the 17th best in the Statcast era (again, among pitchers with at least 60 IP in a season).

Hill did give up a decent amount of base hits, as indicated by his WHIP, despite his strong walk rate. But some of that can be chalked up to his time with the Chicago White Sox. Hill struggled with the White Sox this year (as did nearly their entire roster), with an ERA of nearly 6.00 at 5.87, accompanied by an outrageous .436 batting average on balls in play. After he was traded to the Yankees, he put up a 2.05 ERA with a .238 BABIP, which is what you’d expect from someone who never gets hit hard and induces ground balls at a near-historic rate.

Hill is an older pitcher, turning 35 in February. Hill’s salary was just $1.8 million last year. A one or two-year deal where Hill gets about $2-4 million a season seems reasonable for a decent lefty. He is coming off a very solid season with the New York Yankees, despite his first-half struggles with the White Sox, and would be the sort of southpaw the Pirates need.
