Place onion in a medium bowl, cover with ice water and let soak while you prepare burgers.
Preheat grill to medium.
Place beef in a large bowl and gently mix in cherries, breadcrumbs, garlic, vinegar, mustard, Worcestershire sauce, salt and pepper until combined.
Divide into 4 equal portions and form into ½-inch-thick patties.
Make a slight impression in the center of each. (This is so the patties cook evenly and don’t puff up.)
Oil the grill rack.
Grill the patties until browned and an instant-read thermometer inserted into the center registers 160°F, 5 to 6 minutes per side.
Toast English muffins.
Drain the onions.
Assemble the burgers on the English muffins with onion slices, lettuce and about 1 tablespoon Cherry Ketchup each.
