Rays 6, Rangers 0: B.J. Upton hit three home runs and James Shields tossed a two-hitter for his eighth career shutout to lead the host Rays.

Upton hit solo shots in the first, fourth and sixth innings to become only the third player in franchise history with a three-homer game, joining Jonny Gomes (2005) and Evan Longoria (2008).

Jose Molina added a two-run homer for the Rays, who remain two games out of first place in the American League East. Texas has a 3 1/2-game lead in the AL West, following Oakland’s win over Seattle.

Shields (14-8) struck out eight and didn’t walk anyone while winning for the sixth time in seven decisions. He allowed an infield hit to Nelson Cruz in the second and didn’t allow another until David Murphy lined a single with two outs in the eighth. Shields pitched a perfect ninth to wrap up his second shutout of the season.

Upton hit the first pitch of the game from Roy Oswalt (4-3) over the right-center field. Matt Joyce had a run-scoring double later in the inning.

Molina’s two-run blast in the second gave the Rays a four-run cushion. Upton went deep again in the fourth by hammering a 3-0 pitch from Martin Perez over the left-field fence.

Upton’s third homer was on a first-pitch curveball from Perez in the sixth.

Oswalt left after two innings due to elbow soreness. He allowed four runs and six hits.
