TK's Picks QF day 2: Serena Williams, Pliskova, Rafael Nadal advance to Aussie Open semis

Welp, another of my finalists is out. Will the last one standing, Karolina Pliskova have better luck?

There's another four good matches coming up. Let's be honest we hope they are better then yesterday's because they were not super competitive or entertaining.

Here's my look at today's matches.

Pliskova d. Lucic in 2: Pliskova isn't playing as well as she was at the start of the tournament, but I still think she'll get through this one.

Serena d. Konta in 3: Yes, this will go three sets. Konta is playing out of her mind, kind of like CoCo. But Serena is Serena and she will be at her all-time best when it counts the most.

Grigs d. Goffin in 5: This should be a great match. I think it's simply Grigs' time right now and he will find a way past the feisty Goffin.

Rafa d. Raonic in 5: This also should be a great one. The two split matches in the first few weeks of the season (although one was just an exhibition). This will be a dogfight, and quite frankly I like Rafa's fighting spirit better than Milos'.

Record: 3-1, 228-93
