WSH@SD: Quackenbush retires Span to escape a jam

PHILADELPHIA -- Kevin Quackenbush was summoned in the bottom of the eighth inning with one out and the bases loaded on Tuesday night against the Phillies. The 25-year-old righty won a nine-pitch battle with Marlon Byrd before getting Domonic Brown to whiff on a curveball to end the inning.

Quackenbush owns a 2.93 ERA, and opposing batters are hitting just .140 off him through 15 1/3 innings. In seven appearances since May 27, Quackenbush has seven scoreless innings, allowing two hits and a walk while striking out six.

"He's throwing the ball well," Padres manager Bud Black said. "I think he's gaining confidence. He's pitching with more conviction with his pitches. I think early on he was a little tentative, but now he's settled in."

Black added that Quackenbush drew a lot of praise from his Minor League coaches after posting a 1.26 ERA in 14 1/3 innings pitched and converting all six of his save chances for Triple-A El Paso early this season.

Still, Quackenbush remains a candidate to be sent back down to the Minors as the Padres plan to call a pitcher up to start on Saturday.

"When we activate a pitcher on Saturday, it's going to be a tough move for someone," Black said.

Erlin likely headed toward second MRI exam

MIA@SD: Erlin fans seven in scoreless start

PHILADELPHIA -- Robbie Erlin was examined by team doctors over the weekend, and he will most likely have another MRI exam as he recovers from left elbow soreness.

Erlin hit the disabled list on May 22, retroactive to May 18. He had an MRI exam on May 21 that showed some fluid in his elbow. He had complained of elbow soreness following each of his previous three starts.

The left-hander is 3-4 with a 4.53 ERA in nine appearances, including eight starts.

"He was examined, and I think they want to have one more MRI, one more look to compare it to where he was like three weeks ago when they did it the last time," Black said. "So they're going to compare that and then see if he's good to go as far as getting back on a throwing program."

Tim Stauffer has pitched in Erlin's spot in the rotation.
