According to this very good and useful research (I show here for every category just TOP15 and Ana), Ana very improve hers return game in 2013 compared to previous 2012 season - but there is no any real benefits from that fact simple because hers own serve performances was clearly worse than in 2012... so in general, she has almost copycat season despite all return improvements (but hers serve goes worse).

AMAZING BELGRADE MIRACLE: In just three years (2008-2011) 5 different players born in same city reach world #1 in rankings and several GS titles and finals (WTA singles: Ana Ivanovic and Jelena Jankovic, ATP singles: Novak Djokovic, ATP doubles: Nenad Zimonjic and Daniel Nestor... with notable performances of Bojana Jovanovski, Janko Tipsarevic and Viktor Troicki which is also all three born in Belgrade)
