Fourhand is the Daily Spin's occasional roundup of various hits and misses on tour.

OVERSHARING  When it comes to style sense and the new NikeLab x Sacai collection, Maria Sharapova is a verbal workhorse: "There is a lot of volume in the pieces, so you can layer them really well from season to season. It can be a transitional dress that you wear with sneakers. Or in the winter, you can put pieces together with leggings. It’s a versatile collection that provides you with a lot of options.” And that's hardly all she has to say about the new collection, orchestrated by Chitose Abe, no stranger to the intersection of fashion and sport. Pleats, leggings and more are woven into one's wardrobe in a piece by *Vogue*.

MIXED DOUBLES  The Spin doesn't talk about the beautiful relationship between Ana Ivanovic and Bastian Schweinsteiger nearly enough. So here's this: They stepped out for the Manchester United Christmas Party this past week, and each looked dazzling.

SPIN DOCTORS "Every ball has a different bounce. And every player has a preference." The spherical, fuzzy equipment that all tennis stars use doesn't get a lot of attention. *Sports Illustrated* casts light on this, with comments from Samantha Stosur's coach, David Taylor, and more.

SECOND SERVING  If you missed it, this week Tennis Tuesday serves up the likes of five "closest calls"—competitive matches, that is—on the WTA Tour. Victoria Azarenka versus Angelique Kerber at the U.S. Open, anyone?
