Porcello throws 7 shutout innings, Tigers top Rays

   Rick Porcello allowed four hits in seven shutout innings, Austin Jackson hit a three-run homer and the Detroit Tigers beat the Tampa Bay Rays 6-2 on Saturday night.
 
   Porcello (6-5) struck out four in winning for the third time in four starts.
 
   Jackson put the Tigers up 4-0 with his eighth homer in the eighth off Joel Peralta, who returned after serving an eight-game suspension for having pine tar on his glove.
 
   After Tigers reliever Joaquin Benoit gave up solo homers to pinch-hitter Jeff Keppinger and Carlos Pena in the eighth, Jhonny Peralta gave Detroit a 6-2 lead with a two-run single in the ninth.
 
   Rays starter Jeremy Hellickson (4-4) left in the third after being struck in the lower right leg by Prince Fielder's liner. The Rays said Hellickson, who missed his previous two starts because of right shoulder inflammation, has a bruised shin and X-rays were negative.
 
   Hellickson fell to the ground after being hit by Fielder's bases-loaded shot, which ricocheted to Pena at first base. Fielder was retired by Pena on the play in which Jackson scored to make it 1-0.
 
   After being checked by a team trainer and making a couple warm-up tosses, Hellickson departed and was replaced by J.P. Howell.
 
   Elliot Johnson's third-inning bunt single was the Rays' only hit off Porcello until Will Rhymes, Desmond Jennings and Pena, who had an infield hit just in front of the plate, had consecutive singles to load the bases with one out in the sixth. The Tigers starter worked out trouble by retiring B.J. Upton on a pop fly and getting a grounder from Luke Scott.
 
   Rays right-hander Kyle Farnsworth, out all season with a strained right elbow, pitched a scoreless seventh.
 
   Detroit's Miguel Cabrera went 3 for 3 with two walks. The slugger has 68 hits in 196 at-bats over his last 48 games.
