Having won their division two of the last three years — and having failed to do so last year only because the Colorado Rockies unaccountably won every game they played for two weeks in September — the San Diego Padres were not supposed to have the worst record in baseball this year. So they do, though, and there even have been consequences. Last Friday, at a cost of $5 million, they released their 38-year-old center fielder, who hit .178 with three extra- base hits and 10 walks in 26 games. He might not ever take the field again.
