Arizona Diamondbacks (10-11) At San Diego Padres (8-12)

Aging right-hander Woody Williams will look to make it four straight successful starts today when the San Diego Padres host the Arizona Diamondbacks in the final game of a three-game set at Petco Park.

Williams, who will turn 40 in August, has combined to allow 15 hits and seven runs in 19 innings over his last three outings -- all starts -- in which he's earned one victory and the Padres are 3-0 as a team. He threw a scoreless inning in his first mound effort of the year, a relief appearance in San Francisco on April 5.

The 1988 draft selection of the Toronto Blue Jays was 9-12 with a 4.85 earned run average last season with the Padres and is 5-5 with a 3.13 ERA in 16 career starts against the Diamondbacks.

Orlando Hernandez makes his first career appearance against San Diego in his fifth start of 2006. The Cuban import has dropped three straight since a defeat of Colorado on April 5, allowing 19 hits and 14 runs in 16 1/3 innings in that stretch.

Hernandez was 9-9 with a 5.12 ERA last season in 24 appearances with the Chicago White Sox.

On Tuesday, Claudio Vargas threw seven shutout innings and Conor Jackson went 3-for-5 and drove in a career-high four runs, as Arizona routed San Diego, 7-0.

Luis Gonzalez also had three hits and knocked in two runs, while Craig Counsell went 3-for-5 and scored three times, as the Diamondbacks won for the third time in four contests.

Vargas (2-1) scattered four hits and struck out four. Brandon Medders threw the eighth inning and Greg Aquino finished the five-hitter for Arizona.

Jake Peavy (1-3) was pounded for 10 hits and six runs in 6 1/3 innings to drop his third straight decision, as the Padres fell for the third time in four games.
