PORTLAND — The Portland Sea Dogs (22-12) battled back from a three run deficit and scored four in the ninth to down the New Hampshire Fisher Cats (15-20) 13-12 in Eastern League play on Sunday at Hadlock Field. The two teams combined for 25 runs on 37 hits in the nineinning affair.

The ’Dogs trailed 12-9, deficit as the Mother’s Day marathon of a game entered the bottom of the ninth inning. Mookie Betts and Deven Marrero worked walks to begin the inning against Tony Davis, before he was lifted for Dustin Antolin.

The New Hampshire righty followed suit and walked Travis Shaw, which loaded the bases to begin his outing. Carlos Rivero was the fourth batter of the inning and punched a single to right, which plated two and pulled the Sea Dogs to within, 12-11.

Henry Ramos was next and fouled off a bunt attempt, but got the second try down and reached with an infield single. Matt Spring delivered a gametying sacrifice fly to center that plated Shaw and made it 12-12.

Heiker Meneses ripped a ball through the hole on the left side of the infield, Rivero scored and the Sea Dogs took home the 13-12 walk-off victory.

Robby Scott (4-1) earned the win in relief as he delivered a scoreless ninth inning.

Betts extended his on-base streak to 62 straight games, 67 including playoffs, and 32 straight to begin his Double- A career.

The Sea Dogs have an offday today before resuming action on Tuesday in the opener of a three-game series against the New Britain Rock Cats at 6:35 p.m. from New Britain Stadium.
