I'd say by December the Nats need:
- Lombo at 2B
- Espinosa at SS, with some hitting practice. Hitting .225 is not going to cut it, even with 20 HR (assuming he keeps on atg this pace)
- A hard-hitting LF. No platoon of Nix and Gomes. A guy who hits about .300 with 25 HR.
Pitching will be OK with Strasburg returning. Not world-beaters, but good enough.
