Join us for a new Top10s Photos of the Week! Andrea Petkovic went undercover in a bright pink wig, but you didn’t hear that from us! You can teach old dogs new tricks, as we saw Mansour Bahrami learn ball boy training from a very good boy. There is a new guy in town! Andre Agassi joined Grigor Dimitrov and Darren Cahill, but we don’t think he expected all the extra work! Cool off with Juan Martin del Potro as he took his off season training into the swimming pool! No one balls as hard as Garbine Muguruza, who was courtside at a Lakers vs Heat game. The players have been relaxing in different ways and Alexander Zverev took a colorful approach by painting his beach vacation on canvas. Serena Williams isn’t the only one who has things covered this week, Novak Djokovic decided to keep a low profile at the gym. The camera loves Caroline Wozniacki and her fiance David Lee, who looked picture perfect in Vogue magazine. It’s a very Murray Christmas as we end our list with Andy delivering his letter to Santa. We expect there were a few Grand Slams on his wish list! Tune in next week for another Top10s Photos of the Week!
