The Frederick Keys made their annual sojourn to Memorial Stadium a pleasent one yesterday afternoon. Following the Baltimore Orioles-New York Yankees game, Mike Devereaux, Pete Rose and Mike Richardson combined for seven RBI in a 8-1 victory over the Peninsula Pilots.

The Keys (34-24), have won six of their last seven games and have beaten the Pilots 10 of 11 this season.

Arthur Rhodes, who entered tied for second in the Carolina League in strikeouts (85), struck out nine in seven innings to even his record at 4-4. Rick Balabon (6-3) took the loss.

Devereaux, the Oriole on a rehabilitation assignment for an injured hamstring, had two hits, including a bases-empty home run, and scored three runs.

"I need to prove to myself that I am all right," Devereaux said. "It is nice playing with these guys. They ask a lot of questions about the majors and I know how it feels. But I want to get back with the Orioles."

Shaken by Devereaux's homer leading off the first, Balabon walked Ricky Gutierrez, gave up a bloop single to Tim Holland and walked cleanup batter Ken Shamburg to load the bases. Rose's fly scored Gutierrez. Daniel Berthel's ground ball scored Holland.

The Keys added a run on two hits and a error in the third to take a 4-0 lead. Holland reached when shortstop Bob Holley misplayed his grounder. Shamburg, the league-leader in hits (72) and RBI (48), singled and Rose's double scored Holland.

Rhodes struck out seven of the first 14 batters while giving up singles to Jim Campanis in the second and Holley in the fourth.

"I felt good," said Rhodes. "My fastball was working and I just started to challenge them."

"We got a little bit of everything today." Frederick Manager Wally Moon said. "Arthur pitched well and we got enough hitting."

Peninsula's Damon Saetre singled leading off the fifth, but was stranded when Rhodes struck out Ron Pezzoni and induced twins Delvin and Kelvin Thomas to fly out.

The Pilots (16-44) used two hits and an error to score an unearned run in the sixth to close to 4-1.

Devereaux's two-run single in the bottom of the inning made it 6-1 and finished Balabon, and Mike Richardson's two-run homer in the seventh finished the scoring.

"Home runs feel good, especially at a major league park," Richardson said. "That is where you want to be and now I can say I hit one out of this place."
