Trevor Cahill and Jhoulys Chacin are both having good years, and could easily slide into the final rotation spot in Tampa. Both pitchers would be “rentals” as both are in 1 year deals, so the Tampa Bay Rays would only have control for the rest of the season.
Cahill and Chacin could be perfect targets because the asking price for these players is lower than for Sonny Gray or Yu Darvish. The Rays have a good farm system, and 1 or 2 prospects could likely get a deal done for one of the Padres arms.
