Aided by defensive miscues in the fourth inning, the Lancaster Barnstormers beat the York Revolution 6-4 on Saturday night at PeoplesBank Park.

The game was played as part of the War of the Roses series presented by PNC Bank. The Revs (39-30) will get one more chance to win 40 games in the first half and win their first series of the season against the Barnstormers (34-34).

The Barnstormers profited from Rev mistakes in the top of the fourth. Jeff Kobernus grounded to second to lead off, but Salvador Paniagua dropped Josh Wilson’s throw to first base. Justin Jackson then laid down a sacrifice bunt, but Gailey’s throw got past a covering Brandon Chaves, allowing the runners to reach second and third.

Kevin Ahrens singled home the first run of the game. Then with runners on the corners, Ahrens broke for second, drew a pickoff throw from Gailey and allowed Jackson to come in on a double steal. After a strikeout and a groundout Sean Halton plated another with a base hit to make it 3-0.

Keith Castillo got the Revs on the board in the next half inning with a line drive solo home run to right.

Charlie Cutler took a pitch in the hand with one out in the fifth, and after a Kobernus single Jackson brought Cutler home with a double. Kobernus eventually scored on a passed ball to make it 5-1.

The Revs wasted no time getting back into the game in the bottom of the fifth. Wilson walked and Paniagua reached on an error two batters later. Michael Rockett laced an RBI single, then Chaves drew a walk to load the bases.

Kevin Rivers brought one home with a sac fly. Michael Burgess then smacked a double to left field to bring home Rockett. Chaves took a wide turn at third, though, and the relay throw nailed him off the bag, costing the Revs a chance to bring Castillo to the plate with the tying and go-ahead runs in scoring position.

Blake Gailen fortified the Barnstormer lead with a solo home run in the sixth, giving the game its final margin.

Paniagua started a ninth-inning rally with a one-out double off the Arch Nemesis, but closer Cory Burns struck out the next two batters to finish off the home side.

Mike Lee (4-2) earned the win with five innings of four-run (two earned), six-hit ball, walking three and striking out one. Frank Gailey (2-1) took the loss for the Revs, giving up five runs (two earned) on five hits in five innings, tying a team high for starters with seven strikeouts. Burns’ save was his 14th of the year.

Castillo led the way at the plate for York, going 2-for-4 with a double and solo home run. He left the game with an injury in the eighth inning, allowing Parker Franklin to make his Atlantic League debut behind the plate in the ninth.

New center fielder Jared Mitchell cracked a ground-rule double in his first at-bat with the Revs, finishing 1-for-3 with a walk.

Gailen paced the Barnstormer attack with a 2-for-4 night. The home run was his 60th in a Lancaster uniform, putting him one back of the franchise record.

Notes: Barring a last-minute addition, the Revs will have used 44 different players in the first half of the season, 23 pitchers and 21 position players. PeoplesBank Park saw a crowd of 5,193, 12 shy of a season-high. Rockett finished 1-for-5; he has now hit safely in 19 of his last 21 games (28-83, .337). York saw a nine-game errorless streak snapped; the streak tied a franchise record set during the 2011 season. The Revs and Barnstormers will continue the War of the Roses presented by PNC Bank on Sunday afternoon with a rubber-game matchup of James Simmons (4-3, 4.07) and Bryan Evans (3-3, 3.56).
