| "I'd been a couple steps away at the last Grand 
				Slam, so I'm definitely not ahead of myself," said Williams, the 
				memory of a 6-3 6-3 loss to Angelique Kerber in the Wimbledon 
				final still fresh.
 "I still know that no matter whether I'm in the semi-finals or 
				the finals, I have a really long way to go to win that.
 
 "Again, that proved to be true at Wimbledon."
 
 Williams has done her part, making her way to the last four with 
				her usual efficiency while throwing in an occasional wobble just 
				to keep things interesting but not scary.
 
 But Williams has also received help along the way with others 
				bulldozing the route to Saturday's final clear of some major 
				roadblocks.
 
 When the 36-year-old American first looked at the draw she would 
				have instantly picked out world number one Simona Halep as a 
				potential troublespot, but even before Williams had hit her 
				first ball the Romanian was gone, a victim of a first round 
				upset, eliminating a tricky fourth round encounter with the 
				French Open champion.
 
 Spain's double Grand Slam winner Garbine Murgurza was next to 
				go, making a second round exit, and then earlier on Tuesday 
				Williams side-stepped a semi-final showdown with third seed 
				Sloane Stephens when the defending champion was sent packing by 
				Anastasija Sevastova.
 
 The 18th seeded Latvian is now the only hurdle standing between 
				Williams and a place in Saturday's final where the other side of 
				the draw has also been cleared of potential trouble with 14th 
				seeded American Madison Keys the highest ranked threat 
				remaining.
 
 Williams's 6-4 6-3 quarter-final win over Czech eighth seed 
				Karolina Pliskova on Tuesday was her first over a top 10 ranked 
				opponent since returning to the WTA Tour in March following the 
				birth of her first child.
 
 "That's a really big step for me. Shocking, my first top-10 
				win," said Williams. "I'm here to do my best.
 
 "I don't think I have another 10 years of having opportunities 
				to be able to play and win championships.
 
 "Every match really means a lot to me. I kind of go out there 
				and I just do the best that I can."
