The Portland Sea Dogs will likely have Red Sox left-hander Eduardo Rodriguez start for them on Monday, on a rehab assignment.

Meanwhile, the lefties in the Sea Dogs starting rotation are doing just fine.

Dedgar Jimenez threw five no-hit innings against the Trenton Thunder and Portland pulled out a 6-5 victory Wednesday night at Hadlock Field.

Jimenez was effectively wild, mixing his 90-mph fastball and low-80s slider. He allowed no hits and no runs, but walked four. He also struck out six, throwing 92 pitches (50 strikes).

Jimenez, who did not get a decision, left with a 3-0 lead, courtesy of Bobby Dalbec’s RBI double to left field in the first inning and Chad De La Guerra’s two-run double to left-center in the second.

In the sixth, reliever Jake Cosart allowed an unearned run when Dalbec misjudged a pop-up at third base.

The Sea Dogs answered with two runs in the sixth on Deiner Lopez’s double down the right-field line, but Cosart did not retire a batter in the seventh and left with the score 5-2 and the bases loaded. Trey Ball (3-3) relieved and allowed a sacrifice fly and an RBI single.

In the eighth, Ball gave up an unearned run, tying the game at 5-5.

Portland played small ball in the eighth. Jhon Nunez walked and was sacrificed to second by Danny Mars. Nunez reached third on a wild pitch by Matt Frawley (1-1).

Phillip Diehl relieved. With the infield in, Lopez smoked a hard grounder that third baseman Mandy Alvarez could not cleanly handle, and Nunez beat Alvarez’s throw home for a 6-5 lead.

Portland’s Josh Taylor allowed a leadoff single in the ninth but held on for his fifth save.

NOTES: Rodriguez has been on Boston’s disabled list since he injured his ankle July 14, putting a pause in a solid year (11-3, 3.44 ERA). He threw a 47-pitch simulated game on Wednesday, and reports are that he will make a rehab appearance Monday. Triple-A Pawtucket is off Monday, but the Sea Dogs play host to New Hampshire at 7 p.m. … The Sea Dogs have not announced their 2019 schedule, but Portland apparently will open at home against the Reading Fightin’ Phils on April 4.
