Very early returns would suggest that Castellanos may very well be opting out of the remaining 3 years and $48 million on his contract after this season with the Reds. I wouldn’t be shocked if he found his way back to the Cubs, unfortunately. Again, I know it’s way too early to know for sure, but at just 28 years old I think he could be a candidate to get a longer and more lucrative contract if he chooses to test the FA waters once again. Especially with Mookie Betts off the market, he would seemingly be the best combination of relatively young and productive among corner outfielders. George Springer would also be on the market, but is 2.5 years older and has a more recent injury history. Joc Pederson will also be on the FA market, but is more of a platoon OF option. Michael Brantley is the other big name corner OF, but will be entering his age-34 season next year and may be better suited as a DH in coming years.
