NEW YORK -- New York Mets manager Terry Collins did not challenge a safe call at second base on David Ortiz's pinch-hit double in the ninth inning on Saturday for a good reason.

Jim Kelly, the team’s replay official, advised Collins that Ortiz’s shot to center field appeared to be a home run.

Even though Collins is convinced Ortiz was out at second, he was concerned a Mets challenge would have triggered a review of the entire play and a homer would have been awarded to Big Papi.

Umpire Joe West initially told Collins that a replay review would be limited to the safe or out call at second base, and that the Boston Red Sox would have needed to challenge whether it was a home run. But West got back to Collins an hour later and informed him that had the Mets challenged, the entire play -- including whether it was a home run -- would have been reviewed.
