Andrew McCutchen has hard time chasing ducks off the field at PNC Park (VIDEO)

Andrew McCutchen is pretty territorial when it comes to his turf out in PNC Park and — when a gaggle of ducks invaded his space Monday night — the Pirates outfielder tried to humanely shoo them away.

It was late and Pittsburgh was clinging to a 10-9 ninth-inning lead over the Giants, so one of the Pirates bullpen catchers had seen enough and came out waving his arms to get rid of the feathered intruders.

It worked.

But it was the Giants who ended up with their own ducks-in-a-row and beat the Pirates, 11-10, in a 13-inning marathon.
