"[Jordan Zimmermann] was throwing some pretty good changeups, [and] his late-breaking slider. He looked good," Davey Johnson told reporters this afternoon after watching his 26-year-old right-hander toss a live BP session at the Nats' Spring home. The Washington Nationals' skipper and Nationals' catcher Wilson Ramos have been impressed with what they've seen from Zimmermann early in Spring Training, especially one changeup in particular that caught Ramos off guard and bounced off a mitt he'd already closed, expecting a fastball. Washington Times' writer Amanda Comak talked to the Nationals' '07 2nd Round pick last week about adding the pitch to his repertoire as more of a weapon this season so that opposing hitters have something to think about when preparing to face the starter who finished the 2012 campaign at +3.5 fWAR with a (12-8) record, a 2.94 ERA, 3.51 FIP, 43 walks (1.98 BB/9), 153 Ks (7.04 K/9) in 32 starts and 195.2 IP.
