London: Former Wimbledon Champion Serena Williams on Tuesday beat 148th-ranked Swiss qualifier in straight sets  to cruise into second round of the tournament. 
 
Throughout the match Serena seemed to be struggling with her serve. However, she managed to get the better of  Amra Sadikovic and beat her by 6-2, 6-4. 
 
This was 80th match win of Serena’s  Wimbledon career. Williams  needs one more Grand Slam championship to equal Steffi Graf’s Open-era record of 22 titles.
