Shields is finished for the afternoon

James Shields allows a leadoff infield single in the fifth to Raburn then retires the next two. But he leaves the game shortly after Upton catches Granderson’s drive near the center field wall.

Rays manager Joe Maddon brings in Grant Balfour to pitch to Polanco for two reasons. One, Shields was close to his pitch count, and, two, Maddon wants to get his relievers used to entering games with runners on base.

In Balfour’s case, Raburn was on third, having advanced on St. Pierre’s grounder to third and Granderson’s drive to center, which would have been a two-run homer in most other spring training ballparks.

Balfour ends the inning when Pena leaps at first and catches Polanco’s line drive before it heads into the right field corner.

Shields pitched 4 2/3 innings. He allowed just two hits, walked three, hit a batter and struck out four.

Lopez retired the Rays in order in the fifth.

We head to the sixth with the Rays leading 3-0.
