The Chicago Cubs will look to win the first series they have played at Fenway Park since 2017 and extend their winning streak to five games in a Saturday rematch against the Boston Red Sox.

However, with Kyle Hendricks and Justin Steele both injured, the Cubs did not name a starter for Saturday's game until manager Craig Counsell gave the nod to rookie right-hander Ben Brown (0-0, 3.72 ERA) following the series opener.

Hendricks officially was sidelined on Monday due to a lower back strain.

"What's clear for me in this stretch is that we're going to have to push our starting pitching a little farther in games," Counsell said after Hendricks was shelved. "I think we're equipped to do that and in a good spot to do that, but it's definitely going to be part of the next two weeks."

Shota Imanaga helped the Cubs achieve that goal in Friday's series opener in Boston, tossing 6 1/3 solid innings on 88 pitches in a 7-1 win.

A 14-hit attack supported Imanaga. Michael Busch was 3-for-4 with a double, and Pete Crow-Armstrong was 2-for-3 and drove in two RBIs for the second consecutive game following an 0-for-16 streak to begin his career.

"It's kind of even hard to put into words," shortstop Dansby Swanson said of Crow-Armstrong. "He cares so much. He works so hard. He wants to do so well and has got a great heart."

Two of Brown's six appearances have been starts, and he has allowed just one run on four hits over a combined 10 2/3 innings in those games.

Brown, who made his MLB debut on March 30, has thrown three scoreless frames in two relief outings since his last start on April 15 at Arizona.

The Red Sox are 3-8 this season at Fenway, where they have lost four straight series openers and allowed opponents to score seven or more runs six times.

On Friday, Tyler O'Neill's solo home run in the fourth inning produced Boston's only run against Imanaga.

O'Neill, however, has not hit any of his eight home runs this season with a runner on base.

"Us as a unit, where we're at right now, we have to be better ... understanding what we have to do to have traffic for the big boys," Red Sox manager Alex Cora said. "That's the bottom line."

Along with O'Neill, Rafael Devers is 7-for-13 over his last three games following a five-game injury absence. Cora expects him to return defensively to third base on Saturday.

Boston right-hander Josh Winckowski (1-1, 4.20 ERA) will make his second start of the season and only his third since the beginning of 2023. He dealt 3 1/3 innings of one-run ball last Sunday at Pittsburgh but did not factor into the decision.

Winckowski has been pressed into a starting role with Brayan Bello, Garrett Whitlock and Nick Pivetta on the 15-day injured list.

Winckowski, 25, is excited for another opportunity to prove himself out of a Red Sox rotation that has the best starters' ERA in the American League (2.15).

"Specifically, people were saying we needed help in the rotation and that the rotation (stunk). So I'm really happy for all the guys to be proving everyone wrong," Winckowski said. "I think the team definitely carries a chip on its shoulder to go win as many games as we can."
