DETROIT— Nick Martinez pitched six sharp innings for his first major league win and fellow rookie Rougned Odor drove in five runs with a pair of triples to lead the Texas Rangers to a 12-2 rout of the Detroit Tigers on Saturday.
Martinez (1-1) allowed a run and eight hits, and Adrian Beltre and Donnie Murphy homered for Texas. The Rangers scored four runs in the fourth, plus three each in the sixth and seventh.

Rick Porcello (7-2) had won his last six starts before being knocked around by Texas. He allowed eight runs and 12 hits in 5 1-3 innings.
Detroit has lost five of six.
Leonys Martin, Murphy and Odor — the last three hitters in the Texas batting order — combined for eight hits, eight RBIs and seven runs. Odor had four hits after going 6 for 31 in his first 11 games.
Martinez was making his fourth start of his rookie season for the Rangers, and the 23-year-old right-hander lowered his ERA to 2.14. With Texas ahead 5-1 in the fifth, the Tigers put two men on, but Martinez got Torii Hunter to hit into an inning-ending force play with Miguel Cabrera looming on deck.
Martinez ended his day by getting Nick Castellanos to line into a double play with the bases loaded in the sixth.
The AL Central-leading Tigers have hit a rough patch. They've allowed 45 runs in the last six games, with their normally sturdy starting rotation suddenly looking vulnerable.
For the second time in three days, Detroit used knuckleballing infielder Danny Worth to pitch the final inning of a blowout loss. Worth struck out two against Texas on Thursday, but on Saturday he allowed an RBI double to Michael Choice.
Detroit actually scored first on an RBI double by Rajai Davis in the second, but Porcello allowed four runs with two out in the fourth. Chris Gimenez hit an RBI double and scored on a single by Martin. Odor added a two-run triple.
Beltre hit a solo homer in the fifth, and Murphy's two-run shot the following inning made it 7-1. Mitch Moreland added an RBI double in the sixth, and Odor hit his second triple in the seventh — this one with the bases loaded.
Texas put Prince Fielder on the disabled list this week with a neck problem that is expected to cost the slugger the rest of the season. Outfielder Shin-Soo Choo was pulled in the sixth Saturday with a sore left ankle, although the Rangers said the move was precautionary.
By then, Texas had broken the game open. The Rangers finished with 19 hits.
