Arenado went 1-for-4 with a three-run home run in Tuesday's 7-3 win over the Tigers.
The no-doubt blast was Arenado's seventh in August and 30th of the year. His .307 batting average and .952 OPS remain career highs, and he retook the league's RBI lead from Giancarlo Stanton with Tuesday's performance, putting him at 111 for the season -- and on pace for his third straight season with 130 or more.
