As VAVEL's own Evan Petzold mentioned earlier, the Detroit Tigers have many options at the upcoming trade deadline. Among them, as Petzold suggested, is selling. While David Price and Yoenis Cespedes are likely to be on the block, the Tigers must find someone to trade with to get a good enough return to make it worth selling them.
The Tigers could very easily keep them as well and hold onto their assets to make a run with the current squad. Verlander has always been at his best late in the season, Cespedes has a strong postseason history, and Price has been Cy Young caliber this season. Re-signing all three might not be that difficult if the Tigers are willing to spend.
The Tigers' best option at this point might be holding on to what they have while getting healthy and adding a bullpen arm suc as Aroldis Chapman.
The Tigers' lineup has not been very much of an issue. Rajai Davis and Anthony Gose in center followed by Ian Kinsler at second, Miguel Cabrera at first, Victor Martinez at DH, J.D. Martinez in right field, Cespedes in left field, Alex Avila and James McCann catching, Nick Castellanos at third, and Jose Iglesias at shortstop make a playoff-caliber lineup regarding both hitting and fielding.
The Tigers' trading of Cespedes would take an All-Star caliber bat, a clutch hitter, one of the leagues' best defenders, and a good base runner out of the middle of the lineup, making it more difficult for them to compete with their division rival Kansas City Royals. Cespedes was a Tiger killer in Oakland in the postseason, and trading him to a division rival would ruin all chances of the Tigers' beating Kansas City in the playoff run. The other con to trading Cespedes is that the Tigers could re-sign him much more easily than they could Price, and Cespedes would not bring nearly as large a package.
Trading Price offers much better value, and it could fix the mistake the Tigers made with Max Scherzer by not trading him ahead of last year's trade deadline.
Trading both Price and Cespedes might be an option as well. If the Tigers trade them and other players such as Avila, Davis, Kinsler, and Joakim Soria, they would have an extremely bright future with a still solid lineup.
Trading Castellanos, though, makes very little sense at this time as he is young and cost-controlled. Castellanos has shown significant improvement in many parts of his game, and he will continue to get better as time goes on.
If the Tigers decide to trade Price to the Dodgers for a package based on a top starting prospect (Avila) to the Twins, Davis to a team in need of speed, and Kinsler for a package of prospects, the Tigers could find a second base prospect from one of the trades or call up Dixon Machado. As Petzold mentioned, with McCann replacing Avila and Gose becoming a full-time starter, the Tigers would just need to find a way to improve pitching.
If the Tigers acquire a starting pitcher in a David Price deal much like what the Tampa Bay Rays got in Drew Smyly last year, the Tigers could move Shane Greene, Kyle Ryan, or possibly another starter to the bullpen and make a run for the postseason with a still solid lineup. Verlander, Anibal Sanchez, and Alfredo Simon would be the Tigers' three postseason starters with Kyle Lobstein, Ryan, Greene, and a pitching prospect likely acquired from the Price trade (or, even better, Price himself,) vying for the fourth spot.
The bullpen would include top relievers Blaine Hardy and Alex Wilson, a top reliever such as Chapman (assuming acquisition by trade) as well as the leftover starters with Al Alburquerque and Bruce Rondon for depth.
The ultimate goal of the Tigers is to contend every year, including this season. If the Tigers get healthy, improve their consistency in a good way, and make the right deals before July 31, they should be able to continue doing so.
