Whomever is injured, traded, or awful in spring training. The odds of one of those guys not starting on the DL are not great. Nelson and Anderson have options. And if you're content with those 6 guys as your starting pitchers next year, then that's fine, but to me there's way too much that could go wrong with that set of pitchers. I think standing pat and hoping for the best from those guys is foolish. MLBTR has Morton going to the Royals for 1 year/$8 million, FWIW. Morton, 33 this month, is an under-the-radar rotation candidate who will sign a one or two-year deal. The Pirates traded Morton to the Phillies in December 2015, but he suffered a season-ending hamstring injury in late April. Assuming the medicals check out, the groundballing righty should retain the skills for a sub-4.00 ERA in 2017. The Phillies could bring him back, or the Royals, Braves, Reds, Rockies, Astros, Angels, Marlins, Padres, Mariners, Rangers, and Athletics could be matches. Mr. Lucky To Have An ERA Under 4.00 indeed. $8 million is more than I'd give him, but it wouldn't surprise me if that ended up being a good deal for the team that signed him.
