With the July 31 trade deadline less than four weeks off, there's speculation galore about who the Detroit Tigers should trade.

Slugger J.D. Martinez, 29, seems to be an obvious choice, considering he becomes a free agent after the season and the Tigers are unlikely to be interested in shelling out what he deserves.

Then there are names like pitcher Justin Verlander, 34, and catcher Alex Avila, 30. Pitcher Anibal Sanchez, 33, might even be trade material if he has a couple more good games.

USA Today speculates:

There will be no position player on the market with more value than Martinez, who’s tearing it up since opening the year on the DL, hitting .288 with eight homers, 17 RBI and a 1.202 on-base plus slugging percentage in his first 17 games. The Tigers have yet to determine whether they’ll trade him, but considering they want to go younger and cheaper, he’s the ideal player to start their transition phase should they continue to struggle
