When the Red Sox made their Opening Day roster official on Thursday, the day before the season began, the big surprise wasn’t in who made it, but who was taken off the 40-man and exposed to waivers. That would be Eduard Bazardo, who was thought to be among the top depth arms to start the season in Triple-A but instead was exposed to waivers. It was my thought, at least, and I’m sure that of plenty others, that he’d be claimed despite throwing just once in spring training. Alas, we were wrong. The team announced on Sunday that Bazardo would be outrighted to Triple-A Worcester, which of course means he cleared waivers unclaimed.
