If everything happens that could happen, today will be the busiest day of spring training for the Tigers. With 36 players still in camp, and with manager Jim Leyland hoping to but not guaranteeing he will get down to 25 players by Thursday, there could be several roster cuts. And because of an opt-out clause in his agreement with the Tigers, it could also be the day Don Kelly finds out if he's made the team. Signs are favorable he will. Plus, Leyland might finally be ready to disclose the order of his rotation. This much is known about the order: Justin Verlander will start Wednesday's exhibition against Atlanta, after which he'll get four days' rest before starting the opener in Minnesota next Monday. Drew Smyly also will pitch in a minor league game Wednesday — it could be his tuneup for a role other than starting. Rick Porcello has been Smyly's only competitor for the fifth spot in the rotation and has done everything he can to hold onto it, including a strong outing in a 6-3 victory over the Marlins on Monday. Porcello allowed three runs on four hits in six innings, but his command was excellent. In 24 innings, Porcello hasn't issued a walk. In six starts, he's 4-1 with a 3.00 ERA, and said after this game he's as prepared for this season to begin as he's been for any. If Porcello pitches before the Tigers leave Florida, it will be Saturday against the Rays. Before Saturday, though, there's a lot to get done. The Tigers haven't yet announced their starters for the exhibitions Thursday or Friday — and the order in which the starters make their final appearances of the spring also might be the order in which they'll pitch at the beginning of the season.
