Nats have run their win streak to 9 with their 4th walk-off win in the last 5 games, beating Arizona 3-2. The best part is that both Atlanta and Miami lost, so the Nats now lead by 7 over the Braves and 9.5 over Miami. The only disturbing thing is that the Nats keep blowing leads and putting themselves into a position to have to win in a walk-off. At least they are winning and that's good enough. -- Al
