Denny's is offering a free breakfast as part of a promotion tied to the MLB World Series.
To score a free breakfast, a player from either team must hit a grand slam, a home run with players on all three bases, during the World Series.
This year, Toronto Blue Jays player Addison Barger hit a grand slam home run in the first game, triggering the free breakfast promotion.
A grand slam means a home run with players on all three bases.
Thanks to Barger's grand slam, fans can now enjoy a free breakfast at Denny's.
