VIERA, Fla. — Jordan Zimmermann breezed through two shutout innings with only 20 pitches for the Washington Nationals in what turned into a wild, 16-15 win over the Atlanta Braves on Saturday. Zimmermann, who tied for the NL lead with 19 wins last season, gave up one hit and struck out one in his brief appearance. The right-hander had a lot of success with his changeup last year and was pleased with the pitch on Saturday, particularly in the first inning when he got Atlanta's Freddie Freeman to ground out.
