David Peterson was not on the field for this one, but the key development came early Sunday when Dominic Canzone left the Mariners' game against the Red Sox after appearing to tweak his leg or hamstring while running to first base. He was removed and further evaluated, and Luke Raley moved into right field.
Dominic Canzone and the Mariners
Canzone was holding his hamstring at the end of his sprint through first base, then stayed in the game just long enough to create the split-second concern that usually separates a routine run from a real injury. He kept moving at first, but the finish to the play ended with him leaving the game.
That sequence matters because it gave the Mariners an immediate in-game replacement point. Raley took over in right field as soon as Canzone exited, so the team did not wait for the next half-inning to adjust the defense.
Ari Koslow update
The update was published Sunday at 5:47pm EDT, with the injury described as a possible hamstring issue. The wording leaves the story at the evaluation stage, which is exactly where teams have to sort out whether a player is dealing with a short-term issue or something that will carry into the next day.
For Canzone, the detail to watch is not just that he left, but how he left: he appeared to tweak the leg while running to first, kept going, and then reached for the hamstring at the end of the sprint. That combination usually sends the next step to the medical check rather than to the lineup card.
The Mariners now have to wait for the evaluation to tell them whether right field needs another temporary fix or whether Raley’s move was only a one-game adjustment. Until that comes back, Canzone’s availability is the part that shapes the rest of Sunday’s lineup decisions.
