PORTLAND — The Portland Sea Dogs scored the game’s final four runs and beat the Erie SeaWolves, 5-3 on Thursday night at Hadlock Field in an Eastern League baseball tilt.

With the game tied at two in the eighth inning, Stefan Welch (2-for-4, two triples) cleared the bases with a tworun triple, giving the Sea Dogs a 4-2 lead. Jonathan Roof knocked in the fifth run with a two-out single to left.

Reliever Mike McCarthy (5-2) retired the final 11 batters faced and yielded one hit over four scoreless frames to earn the win. McCarthy did not issue a walk and fanned two.

Felix Doubront lasted four innings in a Major League Rehabilitation Assignment with Portland. Doubront gave up both runs and all three hits in the second inning. Corey Jones led off the frame with an infield single and scored on a throwing error by catcher Blake Swihart. Erie’s second run came on a two-out RBI single from Ramon Cabrera.

Doubront threw 43 pitches (31 strikes), yielding three hits, two runs, no walks and two strikeouts.

Portland cut the deficit to 2-1 with a run off Tommy Collier in the fourth. The Erie righty threw 25 pitches in the inning, but only nine for strikes. Keury De La Cruz and Heiker Meneses each walked, and Derrik Gibson was hit-by-a pitch to load the bases. Bo Greenwell picked up his seventh RBI with a fielder’s choice.

In the eighth, Matt Spring was hit by a pitch. Heiker Meneses moved Roof to second base with a sacrifice. After a wild pitch, Roof scored when Derrik Gibson reached on an error by second baseman Devon Travis.

The Sea Dogs open up a three-game weekend series against the Bowie Baysox tonight at Hadlock Field.
