Top of the mornin'

We're back for Day 5 at the Open, which features plenty of power players who can make a run at the title.

It's tempting to park myself at Arthur Ashe for the afternoon with a lineup that includes Jankovic, Federer and Djokovic for the first three matches. While it's tough to imagine Federer or Djokovic going down, the same cannot be said for Jankovic.

She faces China's Jie Zheng, who made a surprising run to the semifinals at Wimbledon earlier this summer. This could be quite a match given the fact that she made Serena Williams work for her berth in the finals at the All England Club.

Ashe is not completely where it's at today. The Grandstand offers some fun with Davydenko vs. Calleri followed by Ginepri vs. Cilic, who needed five sets to advance out of the first round the other day.

Elena Dementieva, Kuznetsova (vs. Srebotnik) and Safin will play on Louis Armstrong. Should be a fun day. Be back later.
