One of the guys who helped do the damage to Moscoso's season numbers was Ryan Zimmerman, who had three hits, including a sixth-inning home run, last night. Since getting a cortisone shot in his shoulder prior to Sunday's game against the Orioles, Zimmerman has gone 6-for-13 with a home run, two doubles and three RBIs. His average has jumped 14 points over the last three days, but much more importantly, he's finally starting to look like the Ryan Zimmerman that we've seen in a Nationals uniform the last eight years. He's working himself into favorable counts. He's catching up to fastballs up in the zone. He's using the whole field. He's capitalizing on mistakes and stinging the ball. This is a beautiful sight for Nationals fans who have watched Zimmerman suffer through shoulder pain for much of this season. He's grounded into 12 double plays this season, tied for the most in the National League, and has looked like a shell of himself for months. But the last few days have been different. Zimmerman appears to have found a groove again, and the timing of his hot streak is likely no coincidence. The cortisone shot took away the pain in Zimmerman's right shoulder, allowing him to swing free and easy. Who knows how long the shot will work and Zimmerman will be pain-free. Who knows whether the Nationals will be able to give him more shots once this one eventually wears off. For now, though, Zimmerman is locked in and swinging the way we all know he can.
