Two big innings in Monday night's game ultimately cost the York Revolution when it began a pivotal three-game series against the Lancaster Barnstormers.

Lancaster (28-16) scored four runs in both the bottom of the fifth and eighth innings, helping it erase a 2-0 deficit and cruise to the 10-3 win over York (23-20) at Clipper Magazine Stadium.

After the Revs jumped out to a 2-0 lead in the top of the fourth thanks to an Andres Perez leadoff home run and then an RBI double by James Simmons, the wheels began to fall off. The Barnstormers made it a 2-1 game in the bottom half of the fourth and then took the lead with a four-run outburst in the next inning off of York starter Logan Williamson.

After Bryan Pounds homered for the 11th time this season to bring the Revs back to within 5-3 in the top of the sixth, Luis Perdomo gave the run right back in the bottom of the seventh, making it a 6-3 Lancaster. Still, the game wasn't completely out of reach for York to make a comeback. That was, until the bottom of the eighth.

In that frame, Revs reliever Hunter Adkins allowed four runs and the Barnstormers broke the game open, preventing York from having any shot of coming up with some ninth-inning magic.

The loss by the Revs gives Lancaster a 15-11 lead in the War of the Roses. With only two games left between the two clubs, the Barnstormers have won the Community Cup for the first time since 2012. Lancaster also extends its Atlantic League Freedom Division lead over York to a second-half high 4 1/2 games.

Williamson took the loss, falling to 7-10. He wound up pitching 5 1/3 innings, allowing five runs, but just two earned, on seven hits, three walks and three strikeouts. Perdomo's line in relief of Williamson was 1 2/3 innings with one earned run on two hits, one walk and one strikeout. And, in one inning of work, Adkins allowed four runs, all earned, on four hits, two walks and a strikeout.

Nate Reed earned his fifth win of the season for the Barnstormers, going 5 1/3 innings, allowing three runs, two earned, on six hits, three walks and four strikeouts. He's now 5-7.

York will look to pick up the lost game on Tuesday when the two sides play the second game of the three-game set. First pitch is scheduled for 7 p.m. at Clipper Magazine Stadium.
