"She was around home plate, ran up the first base line and ducked into the stands," Mike Pastore, head of field operations for New York City Animal Care & Control, told The News. "We were going to set up a trap behind home plate."
Construction workers told The News that the dog had been wandering around Citi Field for days.
The animal control officers eventually grabbed the dog near the stadium's Jackie Robinson Rotunda, and then named her Jackie after the baseball legend.
The brown-and-cream shepherd mix weighed about 40lbs and was taken to a Manhattan shelter to be evaluated. If healthy, she will be up for adoption within days.
