JZ was drafted by the Washington Nationals in the second round of the 2007 Major League Baseball Draft.In 2008, Zimmermann had a combined 10–3 record with a 2.89 earned run average at high-A Potomac and Double-A Harrisburg, and in July was named to the Eastern League (AA) All-Star team. He finished the season leading the organization in wins, strikeouts, and earned run average, and was the MILB.com Nationals pitcher of the year.In his second game against the New York Mets Zimmermann won his second game in as many starts becoming the first Nationals/Expos pitcher to win his first two starts of his career since Randy Johnson did so in 1988. Coincidentally, Zimmermann was the losing pitcher in Johnson’s historic 300th win on June 4, 2009.

Zimmermann will be out for 12 to 18 months as of July 2009 as he will undergo Tommy John surgery…. Good Luck JZ
