SAN FRANCISCO (Interstat) — The Detroit Tigers bring a three-game winning streak into Oracle Park on Friday, where they open a three-game series against the San Francisco Giants. First pitch is scheduled under clear skies, with the game-time temperature expected at 62 degrees. Detroit (57-59) enters after an 11-0 rout of Seattle on Thursday. Framber Valdez fired seven innings of five-hit shutout ball, striking out five. Dillon Dingler went 3-for-6 with a home run and three RBIs, and Colt Keith drove in two runs. The Tigers improved to 4-1 in their past five games. Valdez remains a player to watch. Before Thursday, he worked seven innings in an 8-6 win at Oakland, allowing two earned runs with six strikeouts. His last rough outing came July 21 at Chicago, when he gave up six earned runs while recording only two outs. San Francisco (48-68) has lost four of its past five. The Giants were shut out 6-0 at Texas on Wednesday, managing only two hits. Right-hander Carson Seymour took the loss after allowing one earned run over 2 2/3 innings.
