DETROIT (AP) Torii Hunter homered and drove in five runs, and the Detroit Tigers withstood a five-run ninth inning by Baltimore to beat the Orioles 7-6 on Saturday.
Rick Porcello (1-0) allowed a run and three hits in 6 2-3 innings in his first start of the season, and the Tigers (4-0) remained baseball's only undefeated team. But the Orioles nearly pulled off a remarkable rally after trailing 7-1 entering the ninth.
Joe Nathan got the final two outs for his first save with the Tigers, retiring Chris Davis on a flyout with two on to end it.
Hunter hit a three-run double in the third, then added a two-run drive in the fifth for his second homer of the year.
Bud Norris (0-1) allowed five runs and nine hits in five innings, and the Orioles lost their fourth straight.
