Pavin Smith hit his first career grand slam, leading the Arizona Diamondbacks to a 6-3 victory over the St. Louis Cardinals on Monday night.

Ketel Marte also homered and drove in another run with a single for the Diamondbacks.

Merrill Kelly (1-2) pitched six innings, allowing five hits and a run. He struck out three and did not walk a batter. Kelly improved to 3-1 in five career starts against the Cardinals. Andrew Chafin earned his third save after facing three batters in the ninth.

Jack Flaherty (1-2) was lifted in the seventh after facing three batters. He gave up four hits. He walked three and struck out four.

Marte led off the seventh with his second homer of the season to give the lead back to Arizona after St. Louis had tied the game in the sixth.
