SAN DIEGO -- Promising rookie Trey Wingenter departed Thursday's 5-1 loss to the D-backs after being hit by a line drive on his pitching arm, and will be day to day, according to manager Andy Green.

Wingenter had recorded one out in his second inning of relief when A.J. Pollock lined a 95-mph fastball back to Wingenter. The comebacker -- measured at an exit velocity of 101 mph -- struck Wingenter on his right arm.

Green indicated he felt the team dodged a bullet, noting that the pitch caught Wingenter in a weird spot above his elbow.

"We didn't need, in that type of situation, to ask him to go much further," Green said. "Stretching him to two innings is rare for him, through his Minor League time he'd only done that a couple times. For us to ask him for that second inning, once he was hit, I wasn't going to ask anything more of him."

Green doesn't expect Wingenter to miss much time, only "a day or two."

Wingenter, who was called up for his Major League debut on Aug. 7 in hopes of further boosting one of the National League's best bullpens, had made four career appearances prior to Thursday's. He's given up one earned run in four innings and had struck out the side for the first time in his career the inning before the injury.

Wingenter posted a 3.45 ERA and 1.20 WHIP in 44 innings in the Minor Leagues before debuting with the Padres.
