WATCH: Daily Mix covers del Potro's chances, Djokovic's health

KEY BISCAYNE, Fla. — It's a stacked men's lineup on Friday at the Miami Open, and so the Daily Mix is breaking down Juan Martin del Potro and Novak Djokovic's chances.

Del Potro is a hot topic right now and it's well deserved since the Argentine is playing some of the best tennis of his life. Last Sunday, the 29-year-old defeated Roger Federer, 6-4, 6-7 (8), 7-6 (2) in the Indian Wells final, marking the first ATP Masters 1000 title of his career.

Instead of resting on his laurels, the world No. 6 is now looking to win the Sunshine Double (which is winning Indian Wells and the Miami Open back-to-back). With Del Potro coming off of the second-biggest victory of his career (the first being his US Open title in 2009), it's hard to count him out, but he's understandably exhausted.

Daily Mix - Nina Pantic talks about Juan Martin del Potro and Novak Djokovic:

As for Djokovic, it's been a long time since anyone saw the 12-time Grand Slam champion playing his best. The Serbian suffered a first-round exit in Indian Wells to qualifier Taro Daniel in match that he never would have lost before.

On Thursday though, the Serbian competed in the doubles draw in Miami, which is something he never would have done if he wasn't fully healthy. It'll be interesting to see how he performs this week after saying he's finally pain-free.

He opens against Benoit Paire, while Del Potro takes on Robin Haase.
