Michelle Wie was in relaxed mood at Killeen Castle on Tuesday. Photo by Jenny Matthews/www.golffile.ieMichelle Wie has hit back at European vice-captain Annika Sorenstam again and insisted that hitting the books has made her all grown up.

Ten-time major winner Sorenstam believes the big hitting Hawaiian has made a mistake by mixing the tour with her degree at Stanford University and isn’t “mentally strong enough to finish at the top.”

But as she prepares to lead the US in Solheim Cup battle with Europe at Killeen Castle this week, Wie reckons that mixing books and birdies was just what she needed to make up for a lost childhood.
