The thing is that Desmond plays SS like a 2B and Espinosa plays 2B like a SS.
I only see the Nats when they play the Muts, but that was enough to see Desmond appear to be hand-cuffed on hard-hit grounders. Desmond hits more like a typical 2B.
Espinosa seems to have range and a strong arm. His hitting, on paper, looks like Eddie Brinkman or Kevin Elster. Brinkman was a good enough fielder that he started st SS for the Nats all through the '60s. Espinosa has a hardr swing, power power, than Brinkman, but he looked a lot like J Maxwell in those last Muts games.
I would switch them and
- work Desmond hard on his defense
- coach Espinosa on his hitting.
