Rangers 9, Mariners 3: Ian Kinsler hit a leadoff home run in the first inning and Josh Hamilton added his major league-leading 42nd blast as host Texas took the opener of the three-game series.

Elvis Andrus doubled and tripled during a seven-run eighth inning while Yu Darvish tossed seven stellar frames for the Rangers, who remained three games ahead of Oakland in the American League West. The Athletics posted a 3-2 triumph over Baltimore on Friday.

Kinsler hit starter Hisashi Iwakuma's fifth pitch of the game into the Mariners' bullpen for a 1-0 lead. The play initially was ruled a double, but Kinsler was awarded his 17th homer after video review.

Hamilton, who sat out Thursday's loss to Cleveland after receiving an injection in his sore left knee, doubled the advantage in the third with a two-out solo shot into the upper deck in right field. Hamilton followed Andrus' leadoff double in the eighth with a run-scoring two-base hit, giving him a major league-high 123 RBIs.

Darvish (15-9) limited Seattle to one run and two hits as he won his third straight decision. The Japanese rookie walked two and fanned nine to raise his season total to 205 strikeouts, making him the 16th rookie since 1900 to eclipse the 200 mark.

Iwakuma (6-5) lasted 5 1/3 innings, allowing two runs and seven hits with one walk and four strikeouts.
