Long Island Ducks add six-year MLB veteran Zach Plesac to rotation

The Long Island Ducks added right-handed pitcher Zach Plesac on April 9, putting a six-year MLB veteran into their rotation at Fairfield Properties Ballpark in Central Islip, N.Y. Long Island said Plesac was beginning his first season with the Ducks and his ninth in professional baseball, a profile that immediately separated him from the usual independent-league arm. For a club that has also leaned on former big leaguers such as Daniel Murphy and Ryan Jackson, the move fit a clear roster pattern: bring in players with enough pedigree to matter from the first inning.

That pedigree is the point. A pitcher with Plesac’s background can lengthen a rotation, take pressure off the bullpen and give Long Island a matchup option against lineups built to attack weaker arms. He arrives with six years of major league experience, which matters in the Atlantic League because hitters are not just facing velocity or a new pitch mix, they are facing a pitcher who has already worked through big-league scouting reports, in-game adjustments and the daily grind of a full season. In a league where roster turnover can be constant, that kind of stability can change the tone around a staff.

The Ducks’ move also tells you what they wanted immediately: a usable arm and a professional standard. Plesac brought the kind of credibility that teammates notice and opponents respect, which is why veteran additions become focal points in this league. Long Island has been active in finding experienced players who can help now, and Plesac fit that template as soon as he arrived in Central Islip.

The next turn came quickly. On June 5, Long Island announced that Plesac’s contract had been purchased by the St. Louis Cardinals organization, and he was set to report to the club’s Triple-A affiliate in Memphis. That made his Ducks stint more than a simple roster patch. It became another example of how the Atlantic League can work as both a proving ground and a launchpad, with a former MLB pitcher using the level to reset his value and push back toward affiliated baseball.
