Sewald gave up a hit and a walk while striking out four over three scoreless innings of relief in Thursday's loss to the Padres.
He replaced an ineffective Rafael Montero in the fourth inning and gave the Mets a chance to mount a comeback, although they'd eventually fall short in a 4-3 loss. Sewald now has a 2.08 ERA, 1.21 WHIP and 20:4 K:BB in his first 17.1 big-league frames, helping to solidify the middle innings for a battered pitching staff, but his role won't afford the 27-year-old much fantasy upside as he has no wins or saves and just one hold in 12 appearances.
