The 2007 Arizona Diamondbacks season was the franchise's 10th season in Major League Baseball and their 10th season at Chase Field in Phoenix, Arizona, as members of the National League West. The season started with the Diamondbacks attempting to win the National League West. The Arizona Diamondbacks' biggest move in the offseason was when, on January 9, 2007, they got their 2001 World Series co-MVP back, pitcher Randy Johnson after making a blockbuster deal with the New York Yankees, sending to New York relief pitcher Luis Vizcaíno and three other prospects. However, Johnson suffered from injuries and underwent season-ending surgery in early August. Despite Johnson's absence and the fact they had fewer runs scored (712) than runs allowed (732), the Diamondbacks had the best record in the National League (90-72), notching their first National League West title since 2002 and their first winning record since 2003.
