PORTLAND – Mike Nicolas simply ran out of gas.

Forced to go out for his fourth inning of relief because the Portland Sea Dogs had nobody left in the bullpen, Nicolas surrendered four runs in the top of the 13th inning to allow the Harrisburg Senators to come away with a 7-4 victory at rainy Hadlock Field Friday night.

After the game, Ron Johnson’s door remained closed with the Portland manager obviously frustrated by the fact his team hasn’t had a hit the last 23 times it has had runners in scoring position while dropping two extra innings games.

The Sea Dogs also had two runners thrown out on the bases when Senators’ pitchers faked a pickoff throw to third and caught the runner leaning off of first, including having the potential winning run cut down in the bottom of the 12th.

“It’s been like that for us lately,” said Portland catcher Kelly Shoppach. “We’ve been fortunate enough to be winning some games. We had every right to be losing all those games.”

Nicolas began the inning by hitting former Sea Dog Jeff Bailey with his first pitch.

Bailey advanced to second on a wild pitch and continued on to third when Shoppach played the carom and threw the ball into center field.

With the infield in, Scott Ackerman blooped a single into center field to give Harrisburg the lead.

Two hits, two walks and a wild pitch later, the Senators had a four-run lead.

The Sea Dogs loaded the bases with one out in the bottom of the 13th against Harrisburg’s fifth pitcher, Chuck Crumpton.

Trace Coquillette drove in one run with a sacrifice fly before Crumpton got Kevin Youkilis to fly to center to end a bizarre night.

“We were pretty much out of pitching there towards the end,” said Harrisburg manager Dave Machemer. “We ended up getting some runs finally.”

The Sea Dogs wasted another solid outing from Eric Glaser.

The only hit the right-hander allowed in six innings was a bloop single to Brandon Watson with two outs in the sixth. Glaser, who moved into the starting rotation when Greg Montalbano went on the disabled list on May 4, walked three and struck out four while lowering his earned run average to 3.12.

The Sea Dogs scored twice in the bottom of the first against Luke Lockwood.

Coquillette homered over the left field wall leading off.

Youkilis followed with a walk and one out later scored from first when Shoppach doubled off the wall in left-center.

Leading 2-0, Sea Dogs loaded the bases with nobody out in the fourth, sixth and seventh innings, but scored only once.

Given a new life, the Senators began to chip away with a single run in the seventh against reliever Charlie Weatherby. An inning later they tied it.

With one out, Watson, Noah Hall and Josh McKinley all singled against Jake Chapman to make it a one-run game. Chapman walked Bailey to load the bases before being replaced by closer Anastacio Martinez.

“We loaded the bases up for them with walks and in the next inning we do the same thing,” said Machemer. “We got a double play and some big pitches and ended up getting out of them. It’s a funny game.”

Martinez struck out Ackerman on three pitches, but walked Glenn Davis to force in the tying run.
