BALTIMORE — Red Sox first baseman Triston Casas has struggled early in the season, going just 2-for-21 (.095 batting average) with no runs, no RBIs, no extra-base hits, one walk and nine strikeouts.

And so manager Alex Cora delivered a message to the 25-year-old in Spanish.

“I talked to him yesterday,” Cora said before Boston’s series finale against the Orioles here at Camden Yards on Thursday. “I said, ‘Bro, let’s go.‘”

Cora said it in Spanish though.

“He knows when I talk to him in Spanish, it means something,” Cora said. “And he felt like he was actually being aggressive. And I was like, ‘You look passive at the plate.’ So just let it eat.”

Cora said Casas’ final at-bat Wednesday was a good one. He singled to center field on a 2-2 slider.

“He’ll get there,” Cora said. “We know that. It’s a process, especially with him. But I would like him to be more aggressive.”

When a reporter mentioned there were more “A-swings” Wednesday and perhaps it had to do with the Spanish, Cora said, “The Spanish. I take credit.”

Cora had said earlier in the week that Casas’ struggles didn’t have to do with swinging at pitches outside of the zone.

“Controlling the strike zone, getting beat in the zone,” Cora said.
