Madson saved 30 games in 2016, the second time he's reached that milestone in three years. He sustained his velocity, which has rebounded since 2010, while notching fewer than 3.0 BB/9 for his sixth straight season and continuing his sometimes decent, sometimes great ability to induce groundballs. That's just about where the positives end, though. After all, he blew seven save chances. Madson's strikeout rate was his lowest since 2006, and his ERA was soared to its highest mark since that same season. He also struggled to get ahead with first-pitch strikes. Perhaps he was fatigued two years removed from a three-year, injury-riddled absence. While his stuff probably will be good enough that he'll improve in the strikeout column, he comes into 2017 as one of the shakiest closers -- that is, if the Athletics don't trade him or demote him. Speculating on a successor likely will pay off more than buying Madson, even at his low market value.
