Rendon went 1-for-3 with a three-run homer in Tuesday's 4-2 victory over the Diamondbacks.
Rendon's three-run shot followed Stephen Drew's sac fly in a four-run sixth inning that accounted for all of Washington's offense. The 26-year-old infielder established a new career high of 84 RBI in this performance, surpassing the 83 he had in a breakout 2014 campaign.
