Infielder Geoff Blum and the Padres agreed to a $900,000, one-year contract Friday that keeps one of baseball's best pinch-hitters in San Diego. Blum, who hit a key home run in the 2005 World Series for the White Sox, batted .254 in 109 games with San Diego last season. But he hit a major league-high .387 (12-for-31) as a pinch-hitter.
