Bob Nightengale of USA Today hears the Diamondbacks and Pirates are "strong front runners" for Brian Wilson. Nightengale says the still-bearded right-hander has five offers -- two from National League teams and one from an American League squad. Wilson looked sharp in a workout for several contending clubs last Thursday and expects to be in a major league bullpen by the middle of August. If he is at full strength, he would make sense for a variety of clubs. The right-hander had Tommy John surgery in April 2012.
