Of their three main trade chips in Matthew Boyd, Shane Greene and Nick Castellanos, the Tigers will have the smallest market for the latter.
The Cubs are starved for more hitting against left-handed pitchers. Castellanos, who leads the majors in doubles, has crushed southpaws this season to the tune of a .387 average and a 1.152 OPS.
The same was true last season, and that trend generally holds up over the course of his career.
Chicago doesn't have much in the way of elite prospects, but Castellanos on his own won't fetch much of a return. Where things could get interesting is if Shane Greene becomes part of the discussion; the Cubs are reportedly interested in the All-Star closer as well.
Together, Castellanos and Greene could likely yield the Tigers one of the Cubs' two prospects ranked among the top 100 in baseball, via MLB Pipeline: shortstop Nico Hoerner (No. 51 overall) and catcher Miguel Amaya (No. 75).
He's gotten hot at the plate after a cold start, which should help the Tigers attract more offers.
