At Fenway Park in Toronto on Friday night, Raimel Tapia hit a rare in-park Grand Slam en route to a historic 28-5 victory over the Boston Red Sox.

With the bases loaded and two outs, Tapia hit what he believed to be an easy flyout to centre field to finish the top of the third inning.

But the ball sailed over Duran's head because he was unable to catch it.

Then, to make matters worse, Duran made no move to go back and get the ball.

adding four more as the Blue Jays increased their advantage to 10-0.

The majors haven't seen a grand slam inside the park since Michael A.

Toronto set a new team record by scoring 28 runs in the last frame.

In the contest, the Red Sox utilised seven pitchers. Only relievers Jake Diekman and Hirokazu Sawamura did not allow a run.
