What has happened to the Arizona Diamondbacks? They tied an MLB record with nine straight series wins to open the season, becoming the first National League team since the 1907 Chicago Cubs to accomplish that; the record-setting 2001 Seattle Mariners did it in the American League.

Following a 12-inning victory at the Los Angeles Dodgers on May 8, the Diamondbacks still hadn’t lost a series. They had the best record in the National League easily at 24-11 and led the NL West by 3.5 games. However, Arizona has won just one game since then and has coughed up the division lead to the Colorado Rockies.

Still, the Diamondbacks remain the +130 favorites to win the NL West, although those odds are much different from a few weeks ago. The Snakes’ slump has brought the five-time defending champion Dodgers (+300) very much back into play to win the West again. They were nine games back on May 8. The Rockies are +333 to win the West for the first time ever.
