You might want to bring Rolaids the next time you visit Fifth Third Ballpark in Grand Rapids.The West Michigan Whitecaps, a minor league affiliate of the Detroit Tigers, has introduced the Fifth Third Burger, a $20 monster already being recognized as one of baseball's most heart-stopping concessions.

The patty uses five-thirds pounds of beef, tying it to Fifth Third Bancorp, the Cincinnati company that owns the stadium's naming rights, on an eight-inch sesame seed bun. A cup of chili, five slices of cheese, salsa, sour cream, Fritos, tomato, lettuce and optional jalapenos complete the 4,800-calorie sandwich. It can be cut up to feed four, but more daring fans can eat the entire thing to win a T-shirt.
