Likewise, an RP for Porcello, or a platoon player for LF? Nope, better to package Porcello if necessary, with Boesch and/or Santiago and/or Worth, and/or Berry, and maybe receive a better return in any trade. Perhaps it would be wise to hang onto Rick, and trade him just prior to the trade deadline next July, IF the Tigers aren't going to be offered anyone who has nearly equal or hopefully better value, just to make a trade in the first place. Almost 2/3 of the season will have been completed by then, and the Tigers might even have their own issues with their roto and already would have needed him to spot start some games, if not pitch a portion of them in long relief earlier.
Since MLB has added another WC slot there will likely be more teams who are contending much later in the season, in at least two divisions in both the NL and AL, and some that may become more desperate to add a SP to their roto, due to injury, unexpectedly poor performance, lack of ML-ready arms in their farm system, or an ill-advised earlier trade.
