Catcher Christian Vázquez got the start at first base Friday against the Blue Jays, further highlighting the Red Sox’ struggles at that position heading into a pivotal part of their season.

Franchy Cordero and Bobby Dalbec, the primary first basemen, haven’t produced. Dalbec came into Friday hitting just .205 with a .629 OPS and 79 strikeouts in 252 plate appearances.

Cordero, meanwhile, is hitting .225 with a .671 OPS after an 0 for 16 slump dating to July 11 in which he’s struck out 15 times.

Franchy, he started off well, and he got cold and then he got hot again and now he’s going through a stretch. He’s not hitting. Bobby, it’s been up and down the whole time,”

manager Alex Cora said before the game. “I just felt like with Kevin Plawecki catching and Nate Eovaldi on the mound, we got Christian at first who can do it. But we need to be better not only there, but I think all around.”

First base has been a grind defensively for Cordero. The Sox threw him into the mix this season, hoping he could learn the position on the fly. That hasn’t happened, Cordero still appearing out of sorts and uncomfortable.

“I think the biggest thing, especially when you have athletes, is they’re going to make some mistakes,” chief baseball officer Chaim Bloom said of Cordero. “But they’re also going to be able to make some great plays because of the things that they can do athletically and we shouldn’t look past that.”

“All the good things that each of them shows you, we haven’t always seen on a consistent basis. Especially with one of them being a lefthanded hitter, the other being righthanded.”
