I think our best hope is that he comes back hot and helps fuel a pennant push and stays as a playoff contributor. Power plays in the postseason and a hot Sano would be a HUGE asset. It feels like a longshot today, but his hot streaks are dominant when they happen and they actually happen. Remember?
We can complain all we want right now, but this decision has to be made on the basis of 2022, not the future. In 2022, rolling the dice on Sano has a chance of a much higher payoff than what could be hoped from Celestino, and honestly more than what we could hope from most bats that could become available on the trade market.
