Pirates designated RHP Dennis Santana for assignment.

The move makes room for fellow reliever Ron Marinaccio, who was acquired from the Padres. How much better off would the Pirates be right now if they had kept David Bednar, instead of taking a poor return from the Yankees, and traded Santana last summer? Santana was great last season, but with his strikeout rate down to 20 percent, he’d posted a 6.05 ERA in 41 2/3 innings this year. He’s a free agent at season’s end and any team that claims him would owe him about $1.5 million over the rest of the year, so there’s a good chance he’ll clear waivers.
