2025 Fantasy Outlook
Quantrill got a one-year, $3.5 million deal to be the Marlins' No. 5 starter in 2025. He will be getting a massive home park upgrade in Miami after spending 2024 with the Rockies, but that's about all that can be said positively about Quantrill's fantasy prospects. Among pitchers who threw 140-plus innings last year, Quantrill's 16.8 percent strikeout rate was the fourth-worst mark, ahead of only Bailey Falter, Austin Gomber and Marcus Stroman. Wins will be very hard to come by pitching for the lowly Marlins as a pitch-to-contact pitcher, so essentially we're talking about a zero-category starting pitcher who is employed by a big-league team to just eat innings.

Making team debut Saturday
Quantrill is slated to start Saturday's game against the Mets at Truist Park, Mark Bowman of MLB.com reports.
Analysis
Erick Fedde had been in line to start this weekend, but he ended up getting moved to the bullpen to open up a rotation spot for Quantrill, whom Atlanta claimed off waivers from Miami on Thursday. Before getting cut by the Marlins, Quantrill had endured a disappointing 2025 campaign, posting a 5.50 ERA, 1.39 WHIP and 82:30 K:BB in 109.2 innings. An impending free agent this winter, Quantrill will look to pitch well over the final five weeks of the season with the hope of earning a rotation spot with Atlanta or another club heading into 2026.

Quantrill's run of success came to a screeching halt last season, as he made a pair of trips to the injured list with shoulder trouble and struggled to an ERA north of 6.00 in his final 12 starts. While it was obvious that the right-hander had been pitching over his skis since coming over from San Diego, it was still somewhat surprising to see his performance crater like it did. The injury almost certainly played a part, but regardless the Guardians designated Quantrill for assignment after the season, later sending him to the Rockies via trade. Quantrill has always been subject to the whims of variance given his low strikeout rate (career 17.7 K%), and adding Coors Field to the mix makes him a highly combustible element. Colorado is hoping he can provide stability in the middle of the rotation, but it will be tough in that division.

Latest Fantasy Rumors

Could get traded this summer
The Marlins could attempt to trade Quantrill before the summer trade deadline, Jim Bowden of The Athletic speculates.
Analysis
Quantrill, a seven-year veteran, has gone 3-6 with a 5.63 ERA and a 1.49 WHIP across 12 starts and 54.1 innings this season. He's unlikely to bring much of a return in a trade, however.
