A popular sleeper candidate heading into last season, Robert Gsellman flopped in a major way, but it's too early to write the 24-year-old off. His strikeout rate fell by more than two per nine from his stellar debut sample in 2016, as he was far too hittable even when he put the ball out of the strike zone (76.0 percent O-Contact%). Although he maintained an above-average groundball rate, Gsellman gave something back in that department, with more balls being elevated and put over the fences. The velocity at which he throws his slider is a bit troubling given the torque on the arm, and he did lose some fastball velocity year-over-year, but as long as Gsellman is healthy, he should be in the mix for starts in New York. Gsellman deserves some consideration as an endgame flier in deep formats, but don't be stubborn and hold onto him if he gets off to a similarly poor start.
Gsellman (8-7) held the Braves to a single run on six hits and a walk over six innings en route to a 7-1 win Wednesday. He struck out four. This was a hard season for Gsellman, but at least he was able to finish on a strong note even if his final numbers -- a 5.19 ERA, 1.50 WHIP and 82:42 K:BB over 119.2 innings -- can best be described as fantasy poison. He'll have the whole offseason now to figure out where things went wrong in 2017.
Gsellman allowed six runs (five earned) on four hits and three walks with four strikeouts over five innings in a no-decision Friday against the Nationals. Gsellman has completed the sixth inning just three times in seven starts since returning to the Mets rotation August 16. His inconsistency can largely be attributed to his poor control. He has walked 15 batters over just 37.2 innings in that stretch with just 21 strikeouts to offset all those free baserunners. Gsellman had allowed two runs or fewer in six of his past seven starts, but the other shoe finally dropped Friday.
Gsellman (7-7) allowed an unearned run on three hits while striking out three batters through seven innings in a winning effort against the Braves on Sunday. It's been a strong late-season stretch for Gsellman, as he's now allowed just 11 earned runs over 32.2 innings through his past six starts. However, he still sports an underwhelming 4.92 FIP and 6.1 K/9 for the season and projects to make his next start against Washington at Citi Field. Gsellman checks out as a risky start against the Nationals in most settings.
Gsellman (6-7) walked five batters and allowed five hits en route to four runs over four innings in Tuesday's loss to the Cubs. He struck out four. For every promising outing Gsellman manages to put together -- like his most recent start before this one, a solid win against the Phillies -- there's always a game like this one that brings expectations right back down. Then again, there's something to be said for a pitcher being as predictable as Gsellman; broadly speaking, he pitches well against bad offenses and poorly against good ones. He comes with risk, but the righty is streamable when the matchup leans his way.
Gsellman (6-6) gave up three runs -- two earned -- on five hits and a walk with four strikeouts while pitching all six innings of Wednesday's rain-shortened win over the Phillies. Maybe a little rain was all he needed, as Gsellman -- taking the mound for the first time since Aug. 26 -- bounced back nicely after averaging less than five innings per start over his last six outings. Overly prone to both homers and walks, Gsellman's largely made his own bad luck this year, and his occasional quality outing can't obscure his general ineffectiveness.
