There are those who aren’t quite buying Ryan Braun’s explanation of why his name is linked to a wellness clinic in the Miami area. Given what he said in an interview Friday on ESPN Radio’s "Mike & Mike" show, you can put broadcaster Bob Costas in that group as well. Costas can’t understand why Braun and his legal team would, while preparing their appeal of his positive test for elevated testosterone last year, be using someone like Anthony Bosch, who directed the Biogenesis clinic that Major League Baseball now is investigating. Costas, who works for the MLB Network and NBC Sports, began his commentary about Braun with the appeal the Brewers’ leftfielder won before the start of last season.
