Red Sox pitcher Eduardo Rodriguez threw four shutout innings at Hadlock Field on Monday, his first rehab start since suffering an ankle injury in mid-July.

The lefthander allowed one hit, walked two, and struck out eight in Portland's 4-3 win over New Hampshire.

"Good stuff. I think the cutter was outstanding," Red Sox manager Alex Cora said. "I think he had only one opportunity to cover or back up or something like that. So he'll come back and we'll go through PFP. The plan is for him to probably go another one and we'll go from there."

Rodriguez was placed on the disabled list after suffering a severe right ankle sprain when he collided with Toronto Blue Jays second baseman Lourdes Gurriel Jr. on July 14.

Rodriguez is 11-3 with a 3.44 ERA in 19 appearances with the Red Sox this season.
