Some folks believe that the Blue Jays sold damaged goods to the Cleveland Indians when they traded Josh Donaldson before the August 30th deadline in 2018, but I don’t think it was a secret that Donaldson had been battling health problems. It also wasn’t a secret that the returning player, Julian Merryweather, had health issues of his own, having been under the knife for a Tommy John surgery prior to the trade.
However, if there either party was “damaged goods” it might have been Merryweather, who has really struggled to get healthy after his elbow surgery in March of last year.
