There's only 1 Serena! Beats sister Venus for a record open-era haul of 23 Grand Slam titles.

Serena Williams rewrote tennis history books once again, this time with sister Venus across the net and her fiance Alexis Ohanian watching from the stands.When Serena beat her older sibling in the Australian Open final 6-4 6-4, she collected a 23rd grand slam title to surpass Steffi Graf for the Open Era lead.

Now she only trails all-time leader Margaret Court by one major and the way she played in Melbourne -- not dropping a set -- Serena, 35, is looking good to achieve that feat later in 2017.

"It's never enough, 23, 24, 25," Serena told the crowd after her win. "I felt like I really elevated my game this year."

Serena had her game face on throughout, but the sisters exchanged an extended hug after Serena converted on her first match point in one hour, 22 minutes. The competitors in them took a backseat.

"Your win has always been my win," Venus told the crowd. "All the times I couldn't be there, didn't get there, you were there."

It simply wasn't meant to be for Venus, who appeared to be the crowd favorite at Rod Laver Arena.

At 36, she was the oldest Australian Open finalist in the Open Era.In keeping with their head-to-head record -- Serena now leads 17-11 and 7-2 in grand slam finals -- it was her kid sister who would have the final say in Melbourne.The sisters have always been close but it was all business, especially from Serena, even before the match -- the oldest grand slam women's final in the Open Era in combined age -- began.

They didn't chat in the tunnel on the way to the court. Venus placed her arm around Serena for the habitual pre-match photo, but Serena kept both hands by her side.

She was clearly focused on the task at hand, perhaps fueled by the fact that in 2016, she lost two of her three grand slam finals. Very unusual.

Later near the locker room Serena exchanged hugs with her team and fiance Ohanian, the Reddit founder. One wondered if parents Oracene Price and Richard Williams -- so instrumental in their daughters' careers -- watched back home in the US.
