The Tampa Bay Rays have acquired their bat. It wasn’t the high-profile acquisition of a player like Justin Upton for which some people were clamoring, but fans should appreciate the fact that the Rays were willing to add to their payroll to improve their current team. They claimed Daniel Nava off waivers from the Boston Red Sox, taking on the approximately $617,000 that he is owed. Though Nava comes with risk, he didn’t cost the Rays any prospects and could emerge as a productive player for them in both 2015 and future years.
