He was named NL co-Player of the Week with Harper for April 18 after leading the NL with four home runs and 12 RBI. He also carried an .852 SLG, led the NL with 23 total bases, and tied for second with seven runs scored. Arenado made his second All-Star Game, played at Petco Park in San Diego. He hit his 100th career home run on August 8, making him the youngest player in franchise history to do so, at just under age 25 years and four months.
