In an organization that stresses pitching and defense, the Frederick Keys have been anything but sure-handed this season. Tonight against the Potomac Cannons, however, it was defense that helped propel the Keys to a 3-2 win before 4,331 in a Class A Carolina League game.

Frederick turned a season-high five double plays, using clutch fielding to navigate their way out of jams.

"Finally we got good defense. We've been waiting for that all year," said Keys Manager Andy Etchebarren, whose team entered the game having committed 155 errors in 109 games.

Noboby benefited more than Matt Achilles (3-6), who allowed one run on seven hits over 7 2/3 innings.

"He pitched very well and used all three of his pitches effectively," Etchebarren said.

After losing four of his first five decisions, the right-hander has won two of three, and would have won all three if not for three errors by the Keys in the seventh inning last Friday against Salem.

The Keys (19-21) took a 1-0 lead in the third on Roberto Rivera's RBI single, and extended it to 3-0 in the fifth on Franky Figueroa's two-run single to center. Figueroa (2 for 4) is batting .354 with 17 RBI over his past 19 games.

Potomac (16-21) got a run back in the sixth when Andy Bevins extended his league-leading RBI total to 83 with a single to right scoring Rob Macrory. The Cannons cut it to 3-2 in the ninth when David Kim, who had grounded into double plays in each of his first three at-bats, hit a solo homer to left.

BAYSOX 10, SENATORS 4: Rick Short and Carlos Casimiro each hit homers as Bowie won on the road. Bowie's Matt Riley (8-3) yielded one run on two hits and struck out five.
