General manager Brodie Van Wagenen said Gsellman will be a rotation option for the Mets in 2019, Matt Ehalt of The Bergen Record reports.
Gsellman transitioned to a relief role in 2018, posting a 4.28 ERA and 70:28 K:BB across 80.0 innings, but it sounds like he could get another look in the rotation next season. The 25-year-old righty has struggled as a starter at the big-league level, notching a career 4.60 ERA and 118:53 K:B in 29 starts (156.2 innings), so he seems more likely to return to the bullpen in 2019, at least to open the season. That said, Gsellman could get a shot in the rotation at some point if an opportunity arises via injuries or underperformance.
