Ken Sims's wild pitch in the ninth scored Junior Brignac from third with the go-ahead run as the Frederick Keys dropped their fourth straight game, 5-3, to Myrtle Beach tonight in a Class A Carolina League game before 6,164 at Harry Grove Stadium.

The Keys (9-13) have dropped seven of eight to Myrtle Beach at home this season, though they have swept the Pelicans in six games in South Carolina, including three straight last weekend.

With the game tied at 3, the Pelicans sent eight batters to the plate in the ninth.

Frederick's Chip Alley led off the third with a double to left -- the catcher's first hit in 17 at-bats since being assigned from Rookie Gulf Coast, where he was rehabilitating an ankle injury. Three batters later, he scored on Darnell McDonald's sacrifice fly, giving the Keys a 1-0 lead.

The Pelicans tied it in the fourth, when Jason Ross led off with a triple into the corner in right and later scored on Brignac's RBI single.

Frederick then regained the lead in the sixth on Roberto Rivera's 10th home run, a solo shot well over the wall in right off reliever Ryan Greene.

Ryan Lehr's two-run homer to left put Myrtle Beach on top, 3-2, in the eighth, but the Keys tied it in the bottom of the inning on Franky Figueroa's two-out single to left that scored Eddy Garabito from third.

SENATORS 7, BAYSOX 6: Andy Tracy hit a solo homer in the bottom of the 10th inning -- his second of the game -- to give host Harrisburg the victory in a Class AA Eastern League game. The teams combined for six home runs and 25 hits.

Tim DeCinces put the Baysox on the board with a solo blast in the first inning, and Rick Short also homered in the seventh. Short also doubled and drove in three runs.

Ryan Kohlmeier (3-6) gave up Tracy's home run to take the loss for Bowie. Christian Parker (6-3) blew the save for Harrisburg -- he gave up a run in the ninth that forced extra innings, but retired the side in the 10th for the win.

INDIANS 4, CANNONS 2: Potomac held host Kinston to just three hits, but two were home runs that lifted the Indians in a Class A Carolina League game.

Jon Hamilton homered off reliever Mike Huffaker (1-4) in the sixth to give the Indians a 3-2 lead, and Dustan Mohr added an insurance run with a solo shot in the eighth.

The Cannons scored both of their runs in the fifth inning as Bob Macrory and Bryan Rupert each had an RBI. Starter Travis Held struck out eight and gave up one hit in five innings of work for Potomac (9-10).
