Martinez went 2-for-4 with two home runs, a walk, two RBI and three runs in Sunday's 11-0 win over the Giants.
After he provided a solo blast in the sixth inning, Martinez's second home run came in between eighth-inning long balls by Paul Goldschmidt and Daniel Descalso, which helped the Diamondbacks break the game open. Since coming over from the Tigers in July, Martinez has gone deep 13 times in just 136 plate appearances, but a .231 average over that span has somewhat dinged his fantasy value.
