Federer wins opening match at Key Biscayne against U.S. teen

KEY BISCAYNE, Fla. - Roger Federer won his opening match Saturday at the Miami Open, returning to the tournament after a two-year absence and beating 19-year-old American qualifier Frances Tiafoe 7-6 (2), 6-3.

Federer took the lead with a flawless tiebreaker after both players held easily throughout the first set, and Tiafoe then became more inconsistent with his groundstrokes.

The resurgent Federer won Key Biscayne in 2005 and 2006, and is among the favorites this year. He is 14-1 in 2017, including his 18th Grand Slam title at the Australian Open and a title at Indian Wells last week.

Stan Wawrinka, seeded No. 1 in an ATP Masters 1000 tournament for the first time, easily won his opening match against Horacio Zeballos, 6-3, 6-4. Wawrinka lost only 13 points in his 10 service games.

Lewis Hamilton takes pole in record pace at F1 Australian GP

MELBOURNE, Australia - Lewis Hamilton took pole position with the fastest lap ever at Albert Park and will start the season-opening Australian Grand Prix at the front of the grid.

The times kept improving during the three practice sessions and the Mercedes driver’s last flying lap in qualifying Saturday was 1 minute, 22.188 seconds. That lowered the mark Sebastian Vettel set in his Ferrari in the last of the three practice sessions, which was already lower than the previous quickest time in Melbourne he set here in taking pole position for the 2011 GP.

Vettel overhauled Mercedes driver Valtteri Bottas for second spot in 1:22.456, but threetime world champion Hamilton had done enough to claim pole in Australia for the sixth time. Kimi Raikkonen was fourth in the second Ferrari.
