O's prospect Bridwell loses perfect game in seventh

For the second time this season Monday, Class A Advanced Frederick right-hander Parker Bridwell carried a no-hitter deep into the game against Potomac. And, for the second time this season, his bid was spoiled by Tony Renda.

Bridwell took a perfect game into the seventh inning. He had retired all 18 batters he had faced, striking out 11 of them. As remarkable as his start to the game was, it was remarkably similar to his start on May 13, the last time he had faced Potomac. On that night, Bridwell retired the first 16 batters he faced and took a no-hitter into the ninth inning, only to see Renda break it up with a one-out single up the middle.

Monday, Bridwell retired the first batter of the seventh inning, bringing Renda, the Nationals' No. 18 prospect, to the plate with the perfect game on the line. And, again, Renda ended Bridwell's bid for history with a single, this time to right field.

Undeterred, Bridwell retired the next five batters to complete eight scoreless innings. Right-hander Brady Wager pitched a scoreless ninth to complete the shutout and Frederick defeated Potomac, 6-0.

Bridwell, the Orioles' No. 12 prospect, finished the night with a season-high 13 strikeouts and no walks. He faced just one batter over the minimum.

With the victory, Bridwell improved to 6-10 with a 4.51 ERA this season. He leads the Carolina League with 136 strikeouts and has walked 67 batters in 135 2/3 innings.
