Tied for the lead as he played the 18th hole at Congressional, Rose tried to hit through two trees left of the fairway and overturned the shot. It ran down a bank and into the water, and he had to hole a 15-foot bogey putt just to stay in the game.
Behind him, Stefani made bogey on the 17th and narrowly missed a birdie putt on the 18th to set up the first playoff in the eight-year history of this event.
Rose and Stefani each closed with a 1-under 70 - only six players broke par in the final round - and finished at 4-under 280.
And then it was Stefani who essentially repeated Rose's mistake on the first extra hole at No. 18. After taking a drop because the grandstands blocked his view of the green, he wanted to play his low punch to the right side of the green. His shot also had too much turn and bounded into the water. Rose hit the middle of the green from the fairway and two-putted for par. Stefani made double bogey.
It was Rose's first win since the U.S. Open last summer at Merion.
ROGERS, Ark. (AP) - Stacy Lewis made a 7-foot birdie putt on the final hole in the NW Arkansas Championship.
The top-ranked Lewis closed with a 6-under 65 for a one-stroke victory. She birdied three of her final holes to finish at 12-under 201 and get her third LPGA Tour victory of the year and 11th overall.
Langer appeared to be in trouble when his second shot on the par-5 18th ended up in the rough short of the green. He hit a brilliant pitch to 5 feet and made the putt after Sluman's birdie attempt rolled just wide.
The victory was the 56-year-old Langer's third of the year and his third major title on the Champions Tour. The two-time Masters champion shot an even-par 70 to finish at 15-under 265 at Fox Chapel.
Bosh told the Heat that he, like James and Wade, will be exercising the early termination option in his contract and forgoing the final two years on his Miami deal - making him a free agent. The move was not unexpected, and gives the Heat a gigantic amount of financial flexibility to shop with when the free-agent window officially opens at midnight Tuesday.
Bosh's decision was the last domino that the Heat needed to fall in order to free up the biggest amount of money possible heading into free agency.
HOUSTON (AP) - Simon Pagenaud, the Frenchman who thought he had a winning car in the first race of the Grand Prix of Houston doubleheader, finally picked up a victory in the second race.
The victory, the second of the season for Pagenaud, allowed him to significantly cut into Will Power's lead in the championship standings. Pagenaud came to Houston down 91 points to Power, but cut it to 59 following his victory.
It was redemption for Pagenaud, who started from the pole Saturday but had his race ruined when he first spun, then was collected in Scott Dixon's crash. He finished 16th in the first race as rookie Carlos Huertas got his first victory and Juan Pablo Montoya finished second.
HOUSTON (AP) - IndyCar fined Marco Andretti $2,500 and placed him on probation for three races for ignoring an order from race control, saying he held up Takuma Sato and allowed his teammate to catch the leader.
Andretti was ahead of Sato and fighting to stay on the lead lap early in Houston on Saturday. IndyCar officials showed him the blue flag - the signal to move over and let Sato pass. Andretti did not heed the flag because he wanted to stay on the lead lap, and that drew a black flag, drive-thru penalty.
GLENDALE, Ariz. (AP) - The Arizona Coyotes acquired center Sam Gagner from Tampa Bay on Sunday night, hours after the Lightning picked him up in a trade with Edmonton Oilers.
The Coyotes gave Tampa Bay a sixth-round pick next year for Gagner and right wing B.J. Crombeen.
The 24-year-old Gagner, the No. 6 pick in the 2007 draft, had 10 goals and 27 assists in 67 games last season. He had 101 goals and 194 assists in 481 games in seven seasons with the Oilers.
Gagner went to Tampa Bay in a deal that sent left wing Teddy Purcell to Edmonton.
ANAHEIM, Calif. (AP) - The Anaheim Ducks acquired center Nate Thompson from Tampa Bay on Sunday night in a trade for two draft picks.
The Ducks sent a fourth-round choice and a seventh-round pick in 2015 to the Lightning.
BUFFALO, N.Y. (AP) - The Buffalo Sabres have bought out defenseman Christian Ehrhoff's contract, making him an unrestricted free agent.
Ehrhoff signed a 10-year, $40 million contract with the Sabres in 2011. He made $18 million over the first two years of the deal.
The Sabres used their second compliance buyout on Ehrhoff. Buffalo also bought out underperforming forward Ville Leino on June 17.
COLUMBUS, Ohio (AP) - Lightning struck outside a soccer stadium before an MLS game, sending an off-duty firefighter who went into cardiac arrest to the hospital and forcing the postponement of the Columbus Crew's game against FC Dallas.
The lightning strike was in the parking lot of Crew Stadium on Saturday night, but it's not known if the off-duty lieutenant was struck directly, Columbus Fire Department Battalion Chief Tracy Smith said.
The firefighter, identified as Lt. Stu Tudor, had to be resuscitated, and was listed Sunday in critical condition in the intensive care unit at the Ohio State Medical Center, Smith said. She said it takes between two and three days to determine the total effects of a possible lightning strike.
The teams played to a scoreless draw on Sunday.
