Folks in Westchester are excited Alex Rodriguez has rented a place in leafy Purchase, where the Yankee slugger and his kids, who are visiting from Florida, can escape Manhattan’s melting asphalt. The added bonus is his girlfriend, Kate Hudson, who’s been spotted with A-Rod in Rye, the nearest village, shopping and chatting with friendly locals. Hudson made one stop in Rags, a clothing store on Rye’s aptly named Purchase Street.
