Back in Arizona, Millwood dominates Padres

PEORIA, Ariz. -- With their regulars getting a night off to reorient themselves to Pacific Time after their season-opening trip to Japan, the Mariners turned things over against the Padres to a collection of promising Minor League athletes -- and one distinguished veteran.

Kevin Millwood, making another strong impression, showed the way for the kids with some resourceful work on the mound, and the youthful Mariners prevailed, 6-1, at Peoria Stadium on Saturday night. Millwood lasted seven innings and 97 pitches, striking out eight while walking two and giving up five hits.

Seattle left fielder Daniel Carroll and catcher John Hicks homered, first baseman Rich Poythress had three singles, and shortstop Brad Miller delivered a big triple.

Padres shortstop Andy Parrino launched his fifth homer of the spring.

Seattle struck first against highly regarded Padres prospect Joe Wieland. Center fielder Denny Almonte's infield hit leading off the third inning was followed by Miller's triple, which seemed to fool center fielder Cameron Maybin. Poythress lined his second single, to center, to cash in Miller.

Millwood (3-1) kept the Padres off the board until Parrino unloaded over the left-field wall with one out in the fifth. Millwood had allowed only two hits and two walks to that point.

The Padres were thwarted in an attempt to draw even in the sixth, a double-play grounder by Yonder Alonso (who had singled and doubled) sandwiched between Will Venable's single and Nick Hundley's double.

After Wieland (0-2) departed with five solid innings (two earned runs, five hits, a walk and five strikeouts), Anthony Bass took over, and the Mariners scored twice.

Stolen bases by Stefen Romero and Joe Dunnigan led directly to both runs in the sixth. Romero swiped his after a one-hit single, and Dunnigan drove him in with a line-drive single to left. After Dunnigan stole second, Jesus Sucre singled him home for a three-run lead.

Facing Micah Owings with one out in the seventh, Carroll went deep to left for his first Cactus League homer.

The Mariners, who split their two games in Japan in the regular-season opening series, moved to 13-8-1 in Cactus League play. The Padres, who wrap up their Arizona schedule on Sunday in Surprise against the Rangers, are 19-14.

Up next: The Mariners, getting acclimated to American soil after their trip to Japan to open the season, plan to have their regulars back in action on Sunday. Blake Beavan is set to start for Seattle against the Royals at 1:05 p.m. PT at Peoria Stadium. Ichiro Suzuki, in his 12th spring in a Mariners uniform, has eight hits in his past 16 at-bats and is batting .400 in 10 Cactus League games.
