Serena Williams and Novak Djokovic Win 2015 Wimbledon Singles Titles

serena williams of the united states defeated garbine muguruza of spain 6-4, 6-4 to win the 2015 wimbledon singles championship. williams now has six career singles titles at the all-england club in london. the historic win on saturday improved her majors finals record to 21-4.

williams became the first player to win four consecutive majors twice; the first time in 2002-03. her unique feat is known as the "serena slam." at 33, she's the oldest to win a major title in the open era - 16 years after her first championship at the u.s. open. the world #1 is one major victory away from tying steffi graf of germany, who has 22 grand slam trophies.

"i've been trying to win four in a row for 12 years, and it hasn't happened. i've had a couple of injuries. you know, it's been an up and down process. i honestly can't say that last year or two years ago or even five years ago i would have thought that i would have won four in a row," williams said.

williams has six titles at the australian open, wimbledon and the u.s. open, and three at the french open. muguruza, 21, upset williams in the second round at roland garros last year. the hard-hitting woman reached her first major final, and will enter the top 10 for the first time in her bright and promising young career.

novak djokovic of serbia beat roger federer of switzerland 7-6, 6-7, 6-4, 6-3 to win the 2015 wimbledon singles title. the world #1 now has nine major singles victories in his career, including three at the all-england club in london. he defeated federer in five thrilling sets last year.

djokovic won the australian open in january, lost the french open final to stan warwinka of switzerland, and defended his wimbledon title against federer on sunday. djokovic has reached 15 of the last 20 major singles finals - winning eight. his major finals record is 9-8, but he's never won at roland garros.

djokovic later praised coach boris becker, whom he hired in december, 2013. becker has six majors, including three at wimbledon. "it's definitely been a long run since we started working together. it took a while to understand each other. he is german. i'm serbian, so there are significant differences! we managed to find common ground and the right chemistry. this is his trophy as much as mine, he said."   
 
the 28 year-old serb now has a 20-20 career record against federer. last year, federer held serve in 88 of 89 games through the semifinals, but was broken four times by djokovic - the greatest returner in history. this year, federer held serve in 89 of 90 matches before the semis, and was broken by djokovic four times (again) in the finals.
