Harrisburg's Tomas De la Rosa continued his season-long pounding of Bowie with two hits, including a key three-run homer that helped the Senators defeat the Baysox, 8-5, in a Class AA Eastern League game last night before 6,659 at Prince George's Stadium.

De la Rosa went 2 for 3 with a walk, three RBI and two runs scored as Harrisburg (58-55) drew to within one game of second-place Bowie (58-53) for the Eastern Division's final playoff spot. He is now batting .360 with two homers and 10 RBI against the Baysox.

The shortstop's fifth-inning double helped the Senators score two runs and sparked their rally from an early 4-1 deficit.

It also ruined yet another strong effort from Bowie starter Mike Bell (7-4), who scattered eight hits over 6 1/3 innings and struck out four. Mario Iglesias came on for Bell but later issued back-to-back walks to Milton Bradley and Jamey Carroll with the bases loaded as the Senators took a 5-4 lead. De la Rosa's three-run homer off Iglesias in the eighth gave the Senators an 8-4 lead.

Moving Bell to the starting rotation in mid-June has caused some problems for Bowie Manager Joe Ferguson -- the left-hander had been solid out of the bullpen with a 4-1 record and a 2.92 earned run average.

"He's done everything you can hope for since [becoming a starter]," Ferguson said. "But we'd sure like to have him in the middle of the bullpen."

Bowie had taken a 3-1 lead in the first as Augie Ojeda hit a two-run homer and Wady Almonte had an RBI single. Cesar Devarez added an RBI single for a 4-1 lead in the third.
