Some Opening Day perspectives on the Tigers' lineup for today: Austin Jackson, centerfielder. It's his fourth Opening Day in the majors -- and his fourth as the leadoff hitter and centerfielder. In both roles he succeeded Curtis Granderson. Torii Hunter, rightfielder. He makes his Tigers debut. The Tigers' Opening Day rightfielder last year was Brennan Boesch. Miguel Cabrera, third baseman. On his first Opening Day with the Tigers, in 2008, he batted fifth. In his next three openers, he hit cleanup. This will be his second straight opener in the third spot ahead of Prince Fielder. Prince Fielder, first baseman. This will be his 344th consecutive regular-season game, the longest active streak of any current big-leaguer. Victor Martinez, designated hitter. Ryan Raburn was the Opening Day designated hitter last year as Martinez began his season-long absence with a damaged knee. "After you sit out a year and you like to play as much as he does, he's probably the happiest guy in the clubhouse," manager Jim Leyland said Sunday. Based on the homers that he launched from both sides of the plate in batting practice Sunday, Martinez looks ready.
