Yoan Moncada hit two home runs and drove in four, leading the Portland Sea Dogs (35-59) to an 11-4 Eastern League baseball win over the Trenton Thunder (57-38) on Monday night at Arm & Hammer Park.

The multi-homer game was the first of Moncada’s career.

Jalen Beeks (1-2) put together his finest Double-A outing, working a season-high six innings on seven hits and two runs, earning his first Double-A win. Beeks allowed solo homers to Lane Adams and Kyle Higashioka.

Portland built an early 2-0 lead off losing pitcher Jordan Montgomery. Mauricio Dubon scored on a wild pitch and Rainel Rosario delivered a run-scoring single. Montgomery fanned 10 batters over 5 1/3 innings on six hits and four runs.

Trenton tied the game, but Portland’s offense took over in the sixth, scoring four times. Ryan Court and Aneury Tavarez had RBI singles and Jake Romanski nailed a two-run single.

Moncada hit his first homer in the seventh, an opposite-field shot off righty Matt Wotherspoon. In the eighth, Moncada blasted a three-run dinger down the right-field line off Travis Hissong.

Portland had 14 hits and leads the league with 21 homers this month. Dubon and Tavarez each had three hits.

The teams meet again tonight at 7 p.m.
