SAN DIEGO - Mets manager Terry Collins still believes that banged-up third baseman Wilmer Flores ultimately won't require a stint on the 15-day disabled list for a sprained right ankle.

But after watching Flores labor to first base while running out his pinch-hit single on Wednesday night, Collins said Thursday a few more days will have to pass before he views the rookie as anything more than a possible pinch hitter.

"I thought about how they might throw him out at first when I saw him come out of the batter's box," Collins said of Flores, who punched a single before giving way to a pinch runner during Wednesday's loss to the Dodgers.

Flores, 22, had not played since spraining his ankle on Monday against the Dodgers.

"It was important that he get an at-bat," Collins said. "Because if he can't play for a few days, at least if we know he can go up and hit, it's going to help us."

Flores has been walking with a protective boot when he's not at the ballpark.

More replay

Collins supports baseball's proposal for expanded video replay beginning in 2014.

However, he wondered about certain situations, such as the "neighborhood play" at second base. In a nod to safety, umpires usually have given second basemen leeway when it come to touching the base -- a concession that may disappear if subject to replay.

Said Collins: "You're going to see some banged-up second basemen."
