ESPN's take:
Detroit Tigers: Subtracting, but not completely. For all the rightful attention lavished on Skubal, any hope of acquiring him would require the sort of overpay almost no one is willing to consider. Teams instead can turn to right-hander Jack Flaherty, the biggest snub of All-Star week. His excellence this season is beyond question, whether it's via ratios (11.5 strikeouts per nine and 1.5 walks per nine) or baserunners (one of nine starters allowing fewer than one per inning), and he would pencil into the playoff rotation of any team that adds him. The calculus with Flaherty is simple: The offer must be stronger than what the Tigers could get with a draft pick in the early 30s, which they'd get if Flaherty signs a large free agent deal as expected. (And the Tigers have drafted very well in recent years.) Like Flaherty, veteran Mark Canha is an impending free agent whose market is robust, and infielder Gio Urshela is a cheap break-glass-in-case-of-emergency option for contenders. The Tigers have taken steps forward this year -- since May 1, rookie Colt Keith is hitting .293/.345/.486 -- and a good deadline is the next order of business before loading up this winter to contend in a suddenly competitive AL Central.
Interesting that Canha has a robust market. He has been getting hot lately.
