Zach Plesac Signs With Long Island Ducks

Right-hander Zach Plesac has signed with the Atlantic League’s Long Island Ducks, the team announced yesterday. He’s the third former big leaguer to sign with the Ducks in the past week, joining Seth Beer and Mark Mathias.

The 30-year-old Plesac has pitched in the majors in each of the past six seasons, albeit for only 12 rough innings with the Angels in 2024. He made three starts for the Halos and was rocked for 11 runs (8.25 ERA) on a dozen hits and seven walks with only five strikeouts. Four of those hits against Plesac were home runs. He spent the rest of the season in Triple-A Salt Lake, where he logged an ugly 5.69 ERA in 99 2/3 innings.

Early in his career, Plesac looked like a potential long-term member of the rotation in Cleveland. He debuted with 115 2/3 frames of 3.81 ERA ball in 2019 and followed that with 55 2/3 innings and a 2.28 ERA the following season. A pedestrian 21.3% strikeout rate and an unsustainable 81.5% strand rate across those two seasons portended regression in his shiny 3.32 earned run average, but Plesac looked the part of an innings-eating fourth starter who relied more on command than overpowering his opponents.

For much of the next two seasons, that’s just how it played out. Plesac started 59 games for the 2021-22 Guardians and turned in a solid, if unremarkable 4.49 ERA. He fanned only 17.2% of his opponents but also limited them to a 6.2% walk rate. His 42.7% ground-ball rate was about average, and while his 1.38 homers per nine frames were too high, that lack of free passes helped to ensure that a fair number of those big flies were solo shots.

Plesac’s velocity and strikeout rate continued to decline in 2023-24, however. The 93.9 mph he averaged on his four-seamer was a distant memory last year, when his four-seamer sat at just 90.5 mph in Triple-A. With fewer missed bats and lesser velocity came more hard contact and more home runs.

Many players have used the Atlantic League — the Ducks, in particular — as a springboard back to affiliated ball. Plesac will hope to be the latest player to do so. He’ll pitch all of this season at 30 and still has three seasons of club control remaining if he ends up back in the majors.
