3 rebound relievers the NY Mets should take a chance on based on Stuff+

The Mets need bullpen depth, and adding it via rebound candidates with good stuff is a smart route to take.

2) Hunter Harvey

Hunter Harvey was once one of the best pitching prospects in baseball. Heading into 2016, he was a consensus top 100 name while in the Baltimore Orioles' system. However, constant injuries took a toll on his health. Those injuries resurfaced during his time with the Kansas City Royals, as he only pitched 16.1 innings with them between 2024 and 2025. However, he was outright elite with the Washington Nationals.

The right-hander spent parts of the 2022 through 2024 seasons with the Mets' division rival, where he had a 3.18 ERA, 2.92 FIP, and 1.08 WHIP. He struck out plenty of batters with a 27.8% K% while keeping walks to a minimum. His BB% clocked in at 6.4%. On top of that, he was not very home run prone, with a 0.74 HR/9 ratio and a 7.2% barrel percentage. Harvey was so good with the Nats, he worked himself into a high-leverage role.

That's when the Nats traded him to the Royals at the 2024 deadline, but his time in KC couldn't have gone any worse. A back problem in early August brought Harvey's season to a complete halt. While he was expected to be healthy for 2025, he landed on the IL again in the second week of April with a right teres major strain. He was reactivated in late July but suffered another setback in August with a grade 2 adductor strain, ending his season.

However, when healthy, Harvey has some impressive stuff. He sat at 98.1 MPH with his fastball with the Nats. His Stuff+ came in at 107. His go-to offspeed pitch, a splitter, came in at 114. His slider was the best pitch in the eyes of Stuff+, coming in at 124. Only his curveball was seen as below average at 98. 

Harvey's health is definitely a question mark. However, it's clear that when he's healthy, he can be a highly effective relief pitcher. Harvey has some impressive stuff, with two pitches that had a Stuff+ over 110 with the Nats, while sitting upper-90s. On a low-cost, one-year deal, it's definitely something the Mets should entertain.
