What do you expect from Donna in 2013 (ranking)?
You didn't specify to whom is this adressed so I'll go ahead and answer; I'd be happy with top 70 and everything above that consider a success. You never know in tennis, injuries and unplanned occurrences happen all the time so I never place the bar too high. Her team alegedly said their goal is top 50, but I don't think that's possible for her this year. Great if she is ready to aim that big, but I don't see it happening with all the age restrictions and mandatory events (i.e. slams) in which one lousy draw can mean an exit with 5 points.
