With her compatriot already advancing to the final, Goerges hoped to make it an all-German affair, but Williams proved too strong in the second of two disappointingly one-sided semi-finals.
A first-ever duel between the two Grand Slam champions with diametrically opposed playing styles ultimately boiled down to a simple mathematical formula.
"I am really happy and proud to be back in the grand slam final". Goerges and Williams lead the aces count this fortnight and, for a player who suffered five first-round losses at Wimbledon before this year, must serve effectively to stand a chance today.
In her third Wimbledon semi-final and seventh at the majors, Kerber landed the first blow with a break, thanks to a wild Ostapenko misfire, in the seventh game of the first set.
The 36-year-old Williams reached her 10th final at the All England Club in just her 13th match since giving birth to daughter Olympia last year.
"I know she played a lot of good matches where she came back from a score like that, when she has nothing to lose", Kerber said.
The left-handed Kerber was mainly a passive participant in the early going against Ostapenko.
She was, instead, going to employ spectacular defense and solid, steady play, while letting her opponent, Jelena Ostapenko, be the one to determine the outcomes of almost every point. That first game consisted of eight points: Three were unforced errors by Ostapenko, including a double-fault to begin the proceedings; the other five were winners by her, including a 100 miles per hour ace to close the hold.
Five games in, Ostapenko led 3-2, and the numbers were still tilted toward her. She had 14 winners and 10 unforced errors, while Kerber had three winners and - this was key - zero unforced errors. On the way to the last-four, she's dropped one set - against Camila Giorgi - in the quarterfinal.
Showing her first sign of nerves Kerber wasted a match point and was broken when she served at 5-1.
