Seems like there's no stopping Serena Williams and her chase to make history.

Serena scored a 6-4, 6-3 victory over her older sister Venus Williams in the Wimbledon quarterfinal on Monday, bringing her one step closer to Steffi Graf (22 titles) and Margaret Court (24) for most Grand Slam singles championships in women's tennis history. Greatness personified.

Before Serena approaches those milestones, though, we wanted to take a closer look at the numbers of what's been a pretty interesting sibling rivalry with Venus.

Counting Monday's Wimbledon quarterfinal, the Williams sisters have now played 26 times, with Serena holding a 15-11 all-time advantage.

Of those head-to-head meetings, Serena has an 8-5 edge against her big sis in Grand Slam tournament matches.

Digging deeper into that set of numbers, Serena also has a 7-2 Grand Slam tournament finals matches record against Venus.

Only 10 of 26 matches between the Williams sisters have gone into 3 sets, spelling that their head-to-head meetings haven't always been the most competitive with one sibling tending to dominate.

Serena has won 6 of her past 7 matches against Venus.

Serena and Venus have 5 Wimbledon titles apiece.

Talk about sisterly domination ... the Williams sisters have won a whopping 28 of the last 63 Grand Slam Tournaments, in which at least one of them has started.

The only years that a Williams sister hasn't won a Grand Slam title since 1999 are 2004, 2006 and 2011.

In career singles Grand Slam titles, Serena has 20 to Venus' 13.
