Roger Federer's 2015 tennis season officially commenced on 4 January 2015 with the start of the 2015 Brisbane International. This season saw Federer slightly improve on his previous results as well as his playing style. He added a new tactic called the SABR ("Sneak Attack by Roger") to his strategy. Like his 2014 season, Federer reached 11 finals. Highlights from his season included winning his 1000th career match in Brisbane, surpassing 9000 aces in Dubai, winning his first red clay court title in almost 6 years at the Istanbul Open, and despite losing before the Australian Open semifinal after 11 consecutive years, he made two Grand Slam runner-up finishes at both Wimbledon and the US Open. Despite the success, Federer dropped a rank to No. 3, ending the year with 6 titles.
