Josh Hamilton opened the scoring with his sixth homer of the season -- and Mike Napoli capped another Texas rout by matching his slugging teammate's total. After a day off because of rain, the Rangers resumed their relentless run. Hamilton hit a three-run homer during Texas' eight-run first inning, and Napoli went deep for a fifth straight game to lead the Rangers to a 10-4 win over the Detroit Tigers on Saturday in the first game of a doubleheader. Texas has won eight straight.
