Casey Frawley roped a walk-off double in the bottom of the 12th, scoring Jovan Rosa, and giving the Southern Maryland Blue Crabs a 6-5 victory over the York Revolution on Monday night at Regency Furniture Stadium.

The extra-inning game was the 11th of the season for York (20-17), tying the franchise record, which was also set in 2009 and 2013.

Monday night's game was again a case of the Revs spotting their opponent an early lead and then having to claw back into the game. This time, York allowed Southern Maryland (14-23) to strike immediately in the first inning and then again for three runs in the third. By the time York came to bat in the top of the fourth, it was already trailing 4-0.

However, the top of the fourth is also when the Revs began their comeback with a little two-out magic. Telvin Nash hit a double, scoring Andres Perez to finally get York on the board. Then, two batters later, James Simmons singled to left field, scoring Bryan Pounds and Nash, to pull the Revs to within one run at 4-3.

After giving a run back in the bottom of the fifth, York scored twice in the top of the sixth, courtesy of a two-RBI triple by Simmons, to bring the score level at 5-5. The game stayed that way all the way until the 12th, when Stephen Penney allowed the game-winning run to score, sending the Revs four games back of the Lancaster Barnstormers in the Atlantic League Freedom Division standings.

Newly acquired pitcher Hunter Adkins made his debut for York after being signed earlier in the day. He lasted 4 1/3 innings, allowing five runs, all earned, on eight hits, three walks and two strikeouts. After he exited the game, seven Revs relievers combined to hold Southern Maryland scoreless over the next 6 2/3 innings, allowing just five hits in the process. Penney only retired one hitter, taking the loss and dropping his record to 3-4.

Offensively, Simmons had the biggest night of any player, going 2-for-5 and driving in four of York's five runs.

The second game of the four-game series is scheduled for 7:05 p.m. Tuesday at Regency Furniture Stadium.
