These two have quite a history, encompassing nine matches. Del Potro won the last one, at Wimbledon in 2013. Ferrer is 34 years old and still a handful.No. 1 Serena Williams versus?Johanna Larsson, not before 1 p.m. ET on Arthur Ashe Stadium (Watch)Worries about the sore right shoulder that forced Serena to withdraw from Cincinnati seem to have vanished. She isnt hitting the ball as cleanly as she would like, but shes been composed, which will help her going forward. Williams is 2-0 head-to-head against the Swedish player.No. 2 Andy Murray versus Paolo Lorenzi, after Serena-Larson (Watch)Murray has looked like the favorite so far, averaging better than 6-3 for each of his six sets. The two have played only once, and it was 10 years ago in Adelaide, Australia. Murray won in three sets.No. 21?Ivo Karlovic versus James Donaldson, fourth match on Court 17 (Watch)??The 19-year-old American has defied gravity so far, and now he has a chance to reach the second week here. Hell have to get past Karlovic, who stroked a US Open-record 61 aces in his first-round match and 24 more in the second.No. 6 Venus Williams versus No. 26 Laura Siegemund, 7 p.m. ET on Arthur Ashe Stadium (Watch)This might be tougher than it looks. Venus, 36, was extended to three sets in her first-round match and tends to fatigue as the matches mount. Siegemund reached the quarterfinals of the Olympics, losing to eventual gold medalist Monic Puig.No. 14 Nick Kyrgios versus Illya Marchenko, after Venus- Siegemund (Watch)Kyrgios, the brash 21-year-old Aussie, has been making waves again this fortnight. You never know what hes going to do on court, but more often than not, he wins. At the US Open, hes won all six sets. Marchenko, the 28-year-old Ukrainian, is one set over the minimum.

Bubba Watson is already thinking about his career after golf, which just might include public office.He wants to run for mayor.Ive had a dream, Watson said. I moved back in the city limits of Pensacola [Florida] so one day I can run for mayor.The two-time Masters champion already is building quite the local enterprise at home. Last year he became a part-owner of the Pensacola Blue Wahoos, a Double A affiliate of the Cincinnati Reds. This year, he opened a candy shop in Pensacola called Bubbas Sweet Spot, serving up premium candy and ice cream.What American doesnt like chocolate? So for me, it was something fun, Watson said. That really is a kid in a candy store, like everyone talks about. We built it from scratch. That wasnt buying a shop.And he didnt stop there. His latest venture is a car dealership, Sandy and Bubbas Milton Chevrolet (he thinks the new electric car is going to be big), along with a robotics company in Pensacola that makes everything from military equipment to toys.He has invested in a few golf courses, and he is involved in an apartment complex being built in Pensacola.Its funny, I say to my friends, I say to my wife, to my manager, to my team that if you say Bubba Watson the golfer, then youre limiting who I am, who I want to be and who I think I am, Watson said at the HSBC Champions. These other businesses are fun. Golf is fun. The golf is great. But there are other things I want to do. I have other dreeams.dddddddddddd Golf made it possible. Luckily for me, havent had bank loans. Im able to pay cash for these things.Watson, who defends his title next week in the Hero World Challenge in the Bahamas, has 10 victories worldwide, and his PGA Tour earnings alone top $35 million. Its more than he imagined when he first reached the PGA Tour in 2006.But at 38, with two children, hes approaching a stage in is life when hes starting to think.He has lived in Orlando, Florida, and Scottsdale, Arizona, and North Carolina. He still keeps a home at The Greenbrier in West Virginia. But his future is near his birthplace of Bagdad in the Florida Panhandle, and he wanted to be sure to live in Pensacola to possibly run for mayor someday.To be back home ... my mom works in the candy shop, he said. The excitement around these businesses, the city of Pensacola realizes I love them. They brought me everything I have now. They took time to sponsor sporting events that I participated in. Thats the same thing Im doing. Im trying to help the community grow.So what would he do as mayor? Given a chance for some humor, Watson turned serious.The first thing you do is some form of education, he said. We talk inner city. Its where the most growth can happen, no matter what background you are. But it all starts with education. ' ' '
