We have a good outlook for 3B for the future, but not in 2019 without Donaldson. Camargo's best role is as a super utility guy and he adds great depth on the bench. Having him as your starting 3B is not as close to the value of Donaldson, which is obvious. And Riley in AAA does not help us right now.
Grandal is not significantly more valuable than a Flowers/McCann combo. So either way you're spending a good chunk of money simply to improve a spot where you're fine right now.
And I'm just playing your game. Find a comment somebody made that wasn't great, and try to rub it in their face forever.
Acuna's first half: .327 BABIP, .746 OPS...almost exactly as I predicted.
What wasn't correctly predicted was his superhuman ability to improve.
Don't worry, you'll be the next target I hound endlessly now since you tossed your hat in the ring.
