Cardinals righthander Adam Wainwright still is seeking his first opening-day victory. Rained out of one potential win and failed by his bullpen in another first-day start, Wainwright was cuffed for 11 hits and four runs, three earned tonight, by the Arizona Diamondbacks before he was lifted after six innings in a 6-2 Arizona victory. Meanwhile, D-Backs’ starter Ian Kennedy was the dominant pitcher Wainwright had hoped to be the week after signing a five-year contract extension. Kennedy allowed a run in the first inning and then blanked the Cardinals on one hit over the next five frames. The Cardinals scored a run in Kennedy’s last inning, the seventh, when Yadier Molina doubled with two out and Daniel Descalso singled. But Descalso was out at second to end the inning as he tried to advance when he saw second base momentarily uncovered. Kennedy fanned eight for the night and, coupled with the bullpen, Cardinals hitters went down on strikes 10 times. Meanwhile, the Nos. 1-7 hitters in the Arizona lineup were 11 for 21 against Wainwright, who didn't walk anybody and fanned six. After three good innings in which he had established his fastball, Wainwright had a bad fourth, giving up three runs as he had trouble with his breaking pitches. "It was a one-inning game," said Wainwright. "The fourth inning I just didn't execute pitches. They made me pay in that inning. "If I execute my pitches in that inning, we're talking a different ball game." Righthander Fernando Salas relieved in the home seventh with the Diamondbacks ahead, 4-2. But, soon it was 6-2.
