BOSTON — A moment of on-field frustration has sparked conversation in the Red Sox clubhouse after center fielder Ceddanne Rafaela was caught on camera throwing up his hands following a play during Saturday's 6-3 loss to the Houston Astros.

The tension surfaced in the fourth inning during Houston's four-run rally. Rafaela fielded Jose Altuve's double off the center field wall with no outs and fired a strong, on-target throw to shortstop Trevor Story. The ball arrived on one bounce, but Story had positioned himself a couple of feet off the bag toward the outfield and couldn't apply the tag on Altuve. That's when Rafaela's visible frustration unfolded.

Story acknowledged Sunday that he hasn't yet spoken with Rafaela about the gesture but made it clear the matter will be handled internally.

"We'll keep it between us," Story said. "That's what I think good teams do. We'll handle it."

This marks the second notable display of emotion from a Red Sox player in three games. On Wednesday in Toronto, starting pitcher Brayan Bello repeatedly shook his head while interim manager Chad Tracy came to the mound to remove him. Back in the dugout, Bello was seen pacing and pounding the railing after a reliever allowed a two-run homer.

When asked if the team needs to show better body language, Story defended his teammates, emphasizing the human side of the game.

"There's a human aspect to it and there's an emotion side to this game," Story said. "That's part of being a professional. You learn ways to handle those things. You're not going to catch me talking bad about any of my teammates."

Red Sox interim manager Chad Tracy echoed that sentiment Sunday morning, saying the players are handling the situation themselves and will be fine.

"There are things that happen in the course of a 162-game season," Tracy said. "Emotions, right? You're trying to get our team on track."
