Jacob deGrom threw his second bullpen session Sunday morning.
He reported no issues with his arm after Sunday's game and said he expects to make his scheduled start tomorrow against the Yankees at Yankee Stadium.
DeGrom left Thursday's game last week against the Phillies in the seventh inning with a right triceps contusion after he was hit by a line drive.
He was immediately checked by team trainer Ray Ramirez, left the game, examined by doctors and not put on the disabled list.
Since giving up eight runs during a start on June 6, deGrom is 9-2 with a 1.82 in his last 11 starts, during which opponents are hitting .189 against him.
