NEW YORK (AP) Bob and Mike Bryan came into last year's U.S. Open without a title in their previous four Grand Slam tournaments an age by their standards.
Now they've won four straight.
The twins figure the margin between those two streaks is slim.
"It's been going our way. We're thankful for that," Bob said Thursday after they started the defense of their U.S. Open title with a first-round win in straight sets. "We've definitely been on the other side of those tough, tough losses."
They return to Flushing Meadows seeking the first men's double Grand Slam of the Open Era, which began in 1968. They're already the first to hold all four major titles at the same time.
