According to Kat O’Brien of the Fort Worth Star-Telegram, "indications are that Mark Mulder is deciding between the Rangers and his previous team, the St. Louis Cardinals, on a two-year deal." Interestingly, the article includes a life-size picture of Mulder’s head.
As far as Mulder’s ERA goes, I don’t think Texas would be a wise choice. Not only is it a tough ballpark, but John Dewan’s recent team defense rankings put the Rangers’ middle infield 23rd in the Majors in 2006. His rankings indicate that the Mets would be a much better choice for a groundball pitcher.
