Serena Williams vs. Garbine Muguruza: Keys to Serena's 6th Wimbledon Title

The idea of Spain's Garbine Muguruza walking onto Centre Court and coming up with the upset of a lifetime and beating Serena Williams in the Wimbledon Final might be the stuff of which legends are made, but it is not going to happen when the two women play for the championship Saturday.

The 21-year-old Muguruza is a talented player with a brilliant future in women's tennis, but it is not her time yet. Serena Williams is the best female player in the world, and she is not going to give up her crown and miss out on her chance at a "Serena Slam."

Williams won the 2014 U.S. Open, and she has also been victorious in the 2015 Australian Open and this year's French Open. Winning Wimbledon would give her four consecutive Grand Slam titles, something she has also done one other time in her career.

With the U.S. Open coming up in late August, a victory at Wimbledon would also give her the chance to complete the calendar-year Grand Slam.

Muguruza has great athletic ability, and she competes hard on every point. She hit the ball much harder than Agnieszka Radwanska in her semifinal victory, as ESPN clocked her hitting the ball between five and 10 miles per hour harder than Radwanska during rallies throughout their match.

That allowed her to win the first set with ease and gain the early advantage in the second set before Radwanska became a wall and simply started returning every shot. The patience and creativity of Radwanska allowed her to win the second set and take an early lead in the decisive third. However, Muguruza found her game at the key moment, and she overpowered Radwanska the rest of the way.

Is Muguruza good enough to overpower Serena? That assertion is laughable because Williams has the hardest serve in the women's game, and she also has the best return of serve. Power vs. power and strength vs. strength is an advantage that goes to the top-seeded Williams 99 times out of 100.

The pressure will be on Williams to earn the victory at Wimbledon, which would be her sixth at the All England Tennis Club. Serena is not immune to pressure, but she has shown she can battle through it and come through when the match is on the line.

Muguruza is a confident player, and while the stage could not be bigger, she is one of the few players who has beaten Serena in a recent major. Muguruza registered a 6-2, 6-2 win at the 2014 French Open over Serena, and that should give her some confidence.

That victory got Serena's attention and she will not go into the Final taking her opponent for granted. "She actually beat me before," Williams said, per Live Tennis. "She made me improve."

Serena simply has too much going for her now, and her experience, agility, strength and desire will be nearly impossible for Muguruza to overcome. Serena is 20-4 in Grand Slam singles finals in her career, and Muguruza is not going to be able to keep her from adding one more victory.

Prediction: Williams, 6-4, 7-5
