Marlins designate left-hander for assignment

The Marlins have designated left-hander Anthony Veneziano for assignment, per a team announcement. His spot on the 40-man roster goes to outfield prospect Jakob Marsee, whose previously reported promotion to the majors has now been officially announced. Miami also optioned righty Ryan Gusto, acquired from the Astros in yesterday’s Jesus Sanchez trade, to Triple-A Jacksonville.

The 27-year-old Veneziano was a waiver claim out of the Royals system last year. He’s pitched a combined 36 2/3 major league innings between those two clubs and logged a solid 3.93 ERA. Veneziano has struck out 20.6% of his major league opponents and yielded a roughly average 8.8% walk rate. He’s also kept the ball on the ground at a respectable 41.4% clip and averaged 94.4 mph on his four-seamer (albeit just 94.1 mph this year, compared to 94.8 mph in 2024).

It’s a decent track record for the former 10th-rounder, although Veneziano has had a much rougher go in Triple-A Jacksonville this season. While he’s only tossed 12 1/3 innings there, he’s been tagged for eight runs (5.84 ERA) on 12 hits and an unsightly nine walks in that time.

Veneziano is in the second of three minor league option years and has had some success at the big league level. Given the limited means of adding depth following the trade deadline, he could latch on with another club via waivers. Miami will place him on waivers within the next five days, and those waivers will take an additional 48 hours whenever the Fish to choose to begin the process.
