Potomac Nationals fans were treated to a sight last night, one Washington Nationals fans haven't seen in nearly two months.

Nationals second baseman Jose Vidro started at designated hitter for Potomac, Washington's Class A affiliate, as part of a rehab assignment with the club. He is recovering from a high sprain and torn tendon in his left ankle suffered May 4 against the Los Angeles Dodgers.

Vidro's RBI single helped Potomac to a 4-2 win over the Kinston Indians but said afterward the tenderness in his ankle prevented him from moving at full speed around the bases.

"It was more mental than anything else," said Vidro, who scored from second base when Frank Diaz stroked a two-out base hit to left-center to put Potomac up 2-0 in the fifth inning. "I didn't want to put too much pressure on it and hurt my knee or my ankle."

Vidro, a three-time National League all-star, was replaced in the sixth after going 1 for 3.

"I'm feeling good," Vidro said. "I'm very happy everything went right. Hopefully tomorrow I will feel the same way."

Vidro, in his ninth season with the organization, played 28 games this spring, batting .290 with 15 RBI and four home runs before getting injured.

Vidro showed some rust in his first two at-bats. He flew out to center leading off the game. His second plate appearance was brief, as Indians left-hander Tony Sipp struck him out on three pitches.

Vidro tucked his chin to his chest and took a view of the dirt on his way back to the dugout after the strikeout.

"I didn't feel comfortable at all in my first at-bat," Vidro said. "Especially facing a lefty . . . I didn't see the ball very good at all."

Vidro got his revenge on Sipp in the fifth inning, hitting a soft shot down the third base line that brought in Seth Bynum from second to make it 1-0.

Vidro told Washington he would start his two first games at designated hitter for Potomac, but seemed eager to test the ankle in the field.

"Our team is playing so good right now, I really, really wish I could be up there with them," Vidro said. "I want to be a part of that."
