Bell started at first base, batted fourth and went 2-for-5 with two solo home runs in Friday's 9-8 win over Pittsburgh.
Bell, who was making his debut for the Diamondbacks, homered in his first plate appearance as part of a five-run first inning. He later tied the game at 7-7 with a solo shot in the seventh. Bell was acquired Tuesday immediately after the Diamondbacks learned starting first baseman Christian Walker (oblique) would miss an estimated three weeks, but Bell's role after Walker returns is uncertain with Joc Pederson boasting a .921 OPS this season as the primary DH against right-handed pitching.
