Ortiz, who had two home runs and six RBI on the night, bailed out De La Rosa, who did not have his stuff from the very first pitch.
De La Rosa allowed runs in each of the four innings he pitched. He gave up six runs in total, allowing nine hits and four walks with two strikeouts.
He put the leadoff man on base each inning, two of which came by way of the walk. In the 4th inning, he gave up a solo shot to Chris Carter that cleared the Monster in center field.
It was one of those nights where nothing seemed to be working for him.
"It was a struggle for him tonight," John Farrell said. "He struggled with his command, he struggled with any type of put-away pitch. He came off an outing where his changeup and the slider were both put-away pitches and that wasn't the case tonight. But after seven or eight starts of which he's thrown the ball very well, sometimes you don't want to assume he's due for an outing like this, but the offense was able to bail him out."
De La Rosa was on a bit of a roll coming into this game. He had allowed just one earned run in his last two starts, both on the road, and was going to pitch at Fenway where he's looked comfortable all season. Over six starts at Fenway this season going into Saturday's game, De La Rosa had a 3-1 record and 1.97 ERA.
Ortiz wasn't the only one who bailed out De La Rosa. The bullpen played a huge role as well, specifically Alex Wilson.
Wilson came on for the Sox in the 5th inning with the Sox down 6-3, and immediately silenced the Astros. He went 2.1 scoreless innings without putting a runner on-base, and earned the win as the Sox put four runs on the board in the 5th inning.
"Gave us a huge lift," Farrell said. "Stabilized the game, gave us a chance to have the offense get on track. The biggest thing is the zero after we scored those runs in the 5th inning. And the times that he's been up here with us, he's been more of a strike-thrower. There's been later actions to his breaking ball. And a key two-and-a-third tonight."
The 2.1 innings pitched matches a season high (also Aug. 2 vs. Yankees).
Burke Badenhop pitched 1.2 innings of scoreless relief as well.
