The Bowie Baysox rallied for five runs in the seventh inning, capped by a grand slam by Augie Ojeda, for an 8-4 victory over the New Britain Rock Cats in the first game of a Class AA Eastern League doubleheader last night before 9,103 at Prince George's Stadium.

Bowie completed the sweep with a 6-3 win in the nightcap.

Left-hander Matt Riley, who came into the game with a 2.13 earned run average, gave up six hits in seven innings but was on the verge of losing his second game of the season before Bowie (38-28) rallied to win the opener.

Carlos Medina (1-5) gave up four hits and three runs in five innings and Rick Short went 2 for 3 with a double and two RBI in the nightcap.

"I'm real pleased with the way things turned out," said Riley, a top prospect in the Baltimore Orioles' organization. "I got a [win], the team got a [win] and I threw another complete game."

Riley (4-1) gave up a leadoff single to John Barnes in the first inning but retired eight of the next nine batters. He ran into a bit of trouble in the fourth inning, giving up two hits and a wild pitch, but escaped with just one earned run.

Bowie took a 2-1 lead in the bottom of the fourth when Carlos Casimiro hit his seventh home run of the season, but Riley walked Barnes and Cleatus Davidson in the fifth and gave up a three-run home to Steve Hacker for a 4-3 Rock Cats (28-39) lead.

Short walked, Wady Almonte doubled and Cesar Devarez was intentionally walked to load the bases with one out in the bottom of the seventh. Casimiro drew a game-tying walk and Ojeda hit an 0-2 fastball over the wall in right field.

"My location of pitches was not as good as I would have liked, but I felt I had really good stuff," said Riley, who walked three and struck out nine in his third straight complete game. "That one bad inning just really hurt me."
