Wimbledon 2015: Serena Williams through to second round

World number one Serena Williams beats debutant Margarita Gasparyan to progress to the second round of Wimbledon with ease.

Five-time champion Williams was broken in the first game of the match, but came through to win 6-4 6-1.

Should Williams triumph at SW19 for a sixth time, the top seed will move closer to completing a calendar Grand Slam and emulate Steffi Graf, who won all four in 1988.
