Carlos Casimiro's RBI single in the bottom of the 10th gave the Bowie Baysox a wild 8-7 victory over the Reading Phillies last night in a Class AA Eastern League game before 10,080 at Prince George's Stadium.

Bowie (34-25) had blown three two-run leads in the game. Reading (26-33) had a chance to win, putting runners on second and third with one out in the top of the 10th, but Baysox reliever Ryan Kohlmeier (3-1) wriggled out of the jam as the Phillies left the bases loaded.

The Baysox had better success in the bottom of the 10th. Tom Hage led off with an infield single, and pinch runner Cesar Devarez went to third on a Tim DeCinces double. Casimiro then won the game by lining a single to left on a 2-2 pitch from Reading's Marty Barnett (0-3).

The Baysox finished with 12 hits, awakening from a recent funk at the plate. Bowie had scored only seven runs in its previous 38 innings while batting only .118 with runners in scoring position.

The offensive problems, which saw Bowie score two runs or less four times, were a big reason why the Baysox lost six of 10 on the road trip that ended Wednesday.

But the Phillies had the problems last night. Reading left 14 runners on base, including nine in the final four innings as it wasted numerous chances to take command. Reggie Taylor and Brian Harris each had three hits for Reading, combining to knock in five of the Phillies' runs.

Bowie got production from several players. Rick Short hit a two-run homer in the first to give Bowie an early 2-0 lead. Wady Almonte's two-run double broke a 3-3 tie in the third. He also had a sacrifice fly for the seventh Bowie run. Ivanon Coffie added an RBI ground out and a sacrifice fly.

KEYS 3, AVALANCHE 0: Sean Douglass, recently activated from extended spring training, pitched five scoreless innings to notch his first win of the season. Relievers Ken Sims and Derek Brown closed out the shutout for visiting Frederick in a Class A Carolina League game before 2,958 at Harry Grove Stadium.

Douglass, Sims and Brown held the Avalanche (29-32) to five hits, all singles, while Frederick's Chris Paxton went 2 for 4 with 2 RBI to lead the Keys (30-32).

CANNONS 9, HILLCATS 5: Andy Bevins had five hits, two of them doubles, scored two runs and had two RBI to lead visiting Potomac past Lynchburg. Billy Deck added a three-run double for the Cannons.
