While fielding grounders in preparation for his first rehab game with Class A Advanced Dunedin on Tuesday, Josh Donaldson suffered a left calf strain that is expected to keep him out through mid-July.
The veteran will be re-evaluated in three weeks, putting his trade value in question as July 31 draws closer.
While the third-base market still has a number of attractive options, Donaldson's latest setback could increase the competition for Manny Machado, Adrian Beltre, Mike Moustakas and even Maikel Franco.
Though Donaldson may still have enough time to make it back before the non-waiver Trade Deadline, contenders will likely be hesitant to trade for a player who has been on the disabled list twice this season and has dealt with persistent calf problems since last year.
Per Blue Jays, Josh Donaldson has suffered a setback while rehabbing in Florida. Happened while he was taking ground balls. MRI revealed an acute strain of his left calf. He'll be reevaluated in three weeks.— Arden Zwelling (@ArdenZwelling) June 26, 2018
Further complicating the situation is the fact that Donaldson has posted his lowest OPS (.757) since 2012 over 36 games in 2018.
