LONDON -- Mike and Bob Bryan moved a win away from their fourth straight major title -- the "Bryan Slam" -- with a five-set victory over Rohan Bopanna and Edouard Roger-Vasselin at Wimbledon on Thursday.

The Americans have won a record 14 Grand Slam tournaments. If they get the 15th this week, they'll become the first team in the Open era to hold all four major titles at the same time.

They had two match points in the fourth set, but couldn't convert. But they broke Bopanna in the first game of the fifth set, when Roger-Vasselin popped up Mike Bryan's low return and Bob Bryan put it away.

The 6-7 (4), 6-4, 6-3, 5-7, 6-3 victory extended the Bryans' winning streak to 23 matches.
