TAMPA — Randy Hippeard's 3-yard pass to Joe Hills with 3.7 seconds remaining gave the Storm a fourth straight victory, 53-47 over Washington at Amalie Arena on Saturday night.
It was the Storm's third winning touchdown in the final 10 seconds of a game.
Washington tied it at 47 when Bernard Morris, in for injured Erik Meyer, found Roger Jackson with 37 seconds remaining. Meyer hurt a hamstring midway through the quarter on a 10-yard run. He fumbled after pulling up lame, and the Storm's Alvin Ray Jackson recovered.
Tampa Bay (5-1) took a 47-40 lead on the ensuing drive, Hills scoring with less than three minutes to go.
Hills finished with 123 yards and three touchdowns. Kendrick Ings also scored three times, all in the second half. Hippeard was 19-of-31 for 233 yards and seven touchdowns.
Ings made up for a major gaffe to start the game. He was headed for a touchdown on the opening kick but started to showboat and fumbled the ball at the 2-yard line for a touchback.
"I was crying inside. Idiot, just idiot," Ings said.
Washington led 26-14 as the first half wound down, but the Storm got a key Hippeard-to-Hills 35-yard touchdown on fourth down late in the half to pull within 26-20. Mike Lindsey forced a fumble on the second-half kickoff, and Tampa Bay soon had the score tied.
Tampa Bay stays in second behind Philadelphia (6-0) in the standings but has a 3.5-game cushion on third place in the five-team league.
The Storm has a bye before hosting Baltimore on June 3.
