The Potomac Cannons did not allow Myrtle Beach ace Derek Lewis to stop their recent offensive surge; they lit up the pitcher with the Carolina League's second-best earned run average with four first-inning runs last night. Potomac starter Finley Woodward (4-6) held the lead despite surrendering three quick home runs in the fifth and the Cannons went on to win, 7-3, at Pfitzner Stadium.

The victory was Potomac's eighth in 11 games against Myrtle Beach (9-11) and left them just 1 1/2 games behind first-place Lynchburg.

"He might have gotten some pitches up in the strike zone in the first inning," Cannons Manager Joe Cunningham said of Lewis. "We showed a lot of poise and composure, and we swung the bats."

The Cannons (9-8) have improved their team batting average since the mid-season break with patient hitting. In the first inning, three singles, a double, an error and a walk put six of the first seven men on base as the Cannons batted around.

Lewis settled down until he was removed in the sixth inning, but the damage was done.

Potomac right fielder William Ortega was 2 for 4 with two RBI to continue his hot streak. He had the game-winning hit Wednesday and five RBI on Tuesday.

Shortstop Jack Wilson, who entered the game hitting .348, also went 2 for 4, including a triple.

Cunningham used three relief pitchers before opting for closer Jason Marr with two on in the ninth. The Carolina League's save leader (16) walked the first batter he faced before before striking out designated hitter Jim Scharrer and getting right fielder Jason Ross to ground weakly to third for an easy double play.

SENATORS 1, BAYSOX 0: Left fielder Jeremy Ware drove home Tomas De la Rosa with the game's only run in the first inning as host Harrisburg (45-47) defeated Bowie before 3,671 at Riverside Stadium.

Matt Riley (6-2) pitched seven innings and took the loss for Bowie (50-40). He allowed one on eight hits, struck out four and walked none.

INDIANS 6, KEYS 2: Frederick pitcher Matt Achilles (1-3) yielded six runs -- only two earned -- over 5 2/3 innings as the visiting Keys (9-11) lost their second consecutive game to Kinston (9-10). Achilles struck out nine and walked six. He and two other Frederick pitchers gave up five hits. Kinston's Mike Spiegel (3-3) earned the victory.
