James Loney's white-hot walloping has upgraded his Dodger future all the way from non-existent to tenuous.By doubling and hitting his ninth homer of the season (and third in four games) tonight in support of Clayton Kerhaw and the Dodgers, who beat the Padres, 4-1, Loney extended his swashbuckling slugging streak to 18 for 35 with five doubles and four home runs in eight games: a .541 on-base percentage, 1.000 slugging percentage and 1.541 OPS.Loney pushed his OPS for the season above .700 for the first time since he doubled in four at-bats on Opening Day. Perhaps more significantly, since he began play on April 24 with his batting average at a season-low .165, Loney has basically been himself, producing an OPS virtually identical to his career .771. The news won't light up Times
