Entering the 2014 season, Blackmon was engaged in a competition for playing time in center field with Brandon Barnes, Corey Dickerson and Drew Stubbs. In the Rockies' home opener on April 14, 2014, Blackmon notched six hits from the leadoff spot in a 12–2 win over Arizona Diamondbacks. He homered, doubled three times, and tallied five RBI. He joined Ty Cobb (May 5, 1925), Jimmie Foxx (7/10/1932), Edgardo Alfonzo (August 30, 1999), and Shawn Green (May 23, 2002) as the only players in MLB history to have six hits, five RBI, and four extra base hits in a single game. Blackmon was named to the roster as a reserve for the National League in the 2014 MLB All-Star Game, the first selection of his career. In his first full season in the majors, Blackmon finished with a .288 batting average, 28 stolen bases and 19 home runs. In 2015, despite a dropoff in the RBI section, Blackmon stole a career high 43 bases while continuing to hit for a high average.
