When the Nationals got healthy in the second half of the season, they had baseball’s best record (33-15) after Aug. 9. They were No. 1 in the NL in both runs and run differential in that stretch, and for a few days, they made a nice run at the NL’s second Wild Card berth.
Perhaps general manager Mike Rizzo’s most significant acquisition is one he has already made, and that’s his new manager, Matt Williams. During a 17-year playing career with the Giants, Indians and D-backs, he became one of baseball’s most respected players, both for his production and his work ethic and competitive fire.
Maybe Davey Johnson was the right guy to lead Washington to respectability, but Williams brings an intensity that could also benefit the club if the players feed off of it.
