AZ opens 3-game series against Padres in San Diego

Posted: Updated:

SAN DIEGO (AP) -- Chad Gaudin had trouble finding the strike zone against Arizona late last month. When he did, the Diamondbacks made him pay for it.

Gaudin's most recent outing was considerably better, and the San Diego Padres will look for a repeat performance tonight as Gaudin seeks redemption against Arizona at Petco Park.

San Diego (25-28) is scoring 3.9 runs per game, worst in the NL. Its starting pitching hasn't been able to compensate for the punchless offense, posting a 4.69 ERA that's in the bottom third in the majors.

Gaudin (2-3, 4.76) has been perhaps the most inconsistent member of the rotation, and that's been especially evident in his past two starts.

The right-hander was roughed up by the Diamondbacks on May 25, giving up five hits, five walks and seven runs over 5 1-3 innings, though he was let off the hook in San Diego's 9-7, 10-inning comeback win.

Doug Davis (2-6, 3.65) will counter for Arizona, and he opposed Gaudin in the May 25 slugfest.

The left-hander gave up five hits and four runs - two earned - in 7 1-3 innings that day.

He was solid again Saturday against Atlanta, allowing two runs over seven innings while striking out six. That wasn't enough to get him his first victory since April 29, though the Diamondbacks went on to win 3-2 in 11 innings.

Davis is 5-1 with a 2.40 ERA in his last seven starts against San Diego.
