TK's Picks QF day 1: Federer, Venus Williams advance to Aussie Open semis

After going a perfect 8-0 yesterday, I'm ready to keep it rolling with my picks today.

There are four great matches scheduled today, all on Rod Laver Arena. Here's how I see things going.

Venus d. Pavs in 2: This will be a competitive two-set match. Pavs will put up a fight, but Venus has experience and Pavs is Pavs.

Mugz d. CoCo in 2: I think this will also be a dogfight. Both are playing great tennis right now. One break of serve in each set can make all the difference. Mugz is a better returner and has more experience in these kinds of matches.

Stan d. Jo Willy in 5: Stan will have his hands full, and I wouldn't be surprised to see Jo Willy win. However, I think Stan will start to play some of his best tennis now, and of course DV is in his box. How can a guy lose with DV in his box?

Fed d. M. Zverev in 3: Each set will be close, but Fed will figure out how to solve the serve-and-volleying Zverev. Get ready for the all-Swiss semi.
