Re: Ana's serve, then and now
Nope... You obviously can't even image how just one or two percents better serve stats is able to make fundamental difference in some players achievements!
For example with 70% percent of 1st serve points won from 2007 Ana will be #6 in 2013 instead #21 with 67%. With 48% winning points on 2nd serve she will be #10 instead #22 with 47%, and with 74% service games won from 2007 she will be #4 in that category in 2013, instead #18 with 70%... etc... Also don't forget that Ana's 2007 season before amazing claycourt May's breakthrough (Berlin title, RG final) was pretty mediocre (she is around #15 in YEC RACE).
But also, fact is that hers return game stats is much better in 2013 than in 2012, and very similar (even slightly better!) like for 2007 season which she finished like TOP5 player. To make improvement in 2014 Ana should to continue to improve hers return game stats, or to hold them on current level with recovering hers serve stats at least on 2012 level. In general, Ana's 2013 serve stats are one of worst she ever have for some season, but hers return game stats are probably second best ever (after golden May2007-June2008 period).
and I'm not even fan of Ana Ivanovic... just an objective observer who realize how perfect she is
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)
