Dunn's fist Arizona homer powers Diamondbacks

Posted: Updated:

PHOENIX (AP) -- Adam Dunn hit his National League-leading 33rd home run in his Arizona home debut, powering the Diamondbacks to a 7-6 victory over the San Diego Padres on Tuesday night.

Conor Jackson had two hits and two RBIs for the Diamondbacks, who have won four of five and six of eight.

Arizona starter Doug Davis (5-7) scattered seven hits over six innings for his first win since July 29, and his second win in his last nine starts. Tony Pena recorded the final two outs for his second save -- and first since May 16 -- in five chances.

Adrian Gonzalez had four hits and two RBIs for the Padres, who have lost five of seven.

Dunn was acquired by Arizona from the Cincinnati Reds on August 11th. He made it 6-2 with a towering two-run homer in the fourth. Dunn tied Philadelphia's Ryan Howard for the NL lead and moved within two homers of former D-back Carlos Quentin of the Chicago White Sox for the major league lead.
