LONDON: Before looking ahead to the Wimbledon final between Serena Williams and Angelique Kerber on Saturday, take a moment to look back at the American's second-round match last week.

After dropping the opening set against Christina McHale in a ragged tiebreaker, Williams plopped herself in her sideline chair and proceeded to smack her racket repeatedly against the grass, before flinging the equipment so far behind her that it landed in the lap of a TV cameraman.

That display earned six-time Wimbledon champion Williams a $10,000 fine. And, more importantly, she has won all 10 sets she's played since.

"Sometimes when I release that energy, I get kind of calm," Williams said. "I just sometimes feel like maybe I need to release."

Might Venus offer Serena any advice about how to beat Kerber?

"I'll give her a few pointers," Venus said. "For the most part, she's got to go out there and play the match she wants to play, not that I want her to play."

Williams-Kerber II represents the first time in a decade that two women play each other in a pair of Grand Slam finals in the same season: Amelie Mauresmo defeated Justine Henin for the Australian Open and Wimbledon titles in 2006.

Can Kerber go 2-for-2 against Williams?

"I will just try to (go) out there like in Australia," Kerber said, "trying to show her, 'OK, I'm here to win the match, as well.' I know that I have to play my best tennis to beat her in the final."
