With the score tied at seven in the bottom of the ninth at Coors Field, Rockies catcher Chris Iannetta makes Evan MacLane’s major league debut memorable when he leads off the inning with a game-ending home run off the 27 year-old rookie.

Trujillo accomplished the dubious deed in his major league debut by allowing Baltimore’s Tony Batista to end a game with a round-tripper in 2002.
