PORTLAND

Luke Tendler swatted a two-out, three-run walk-off home run to give the Portland Sea Dogs a 5-2 Eastern League win over the Trenton Thunder on Tuesday night at Hadlock Field.

Tate Matheny had tied the game with an RBI single before Tendler came to bat.

The excitement followed seven scoreless innings. Both teams scored in the eighth. Portland tallied on back-to-back doubles by Michael Chavis and Bobby Dalbec with two outs.

Portland left-hander Kyle Hart pitched seven scoreless innings, allowing six hits and one intentional walk. He struck out four and lowered his ERA to 3.55.

Hart gave up only two singles and no walks through the first five innings — but also picked off two runners. Hart yielded two singles in the sixth inning, and escaped a bases-loaded, one-out jam in the seventh.

It was Hart’s second impressive start in the past two weeks. He pitched seven scoreless innings on Aug. 2, allowing two hits. He was named Eastern League Pitcher of the Week for that performance.

Portland faced the reigning Pitcher of the Week, Trenton lefty Ryan Bollinger. He matched Hart with seven shutout innings (seven hits, no walks and five strikeouts).

NOTE — The announced paid attendance was 5,574 … The game was delayed 88 minutes because of rain.
