Mariners continue to ride great pitching

SAN DIEGO — Rookie Michael Pineda allowed only two hits while striking out nine in seven innings and Mike Wilson had two run-scoring hits to lead the Seattle Mariners to a 4-0 win Saturday night against the San Diego Padres, who continue to struggle at Petco Park. Pineda (6-2) and relievers David Pauley and Jamey Wright combined on a four-hitter and struck out 13. The Padres were shut out for the ninth time, the most in the majors. San Diego’s home record of 8-17 also is the worst in the bigs. The Padres have totaled one run, eight hits and 22 strikeouts in the first two games of this series, and must face reigning A.L. Cy Young Award winner Felix Hernandez on Sunday. They’ve struck out 39 times in the first four games of this eight-game homestand.
