Juan Castro, and not Greg Dobbs, will start at third against a right-hander.
Preview: Placido Polanco continues to battle soreness in his left elbow joint stemming from an April 21 plunking at the hands of the Braves. Polly, who reportedly will have an MRI Sunday, sits for a second-straight game as right-handed aces Roy Halladay (2-2, 2.22) and Josh Johnson (5-1, 2.43) square off in the second of three from Sun Life Stadium. First pitch is 7:10. Beerleaguer: Interesting situation developing among the third-base pecking order. Juan Castro, who is hitting just .237 against right-handers, starts at third over Greg Dobbs. Dobbs, who has had a miserable season in ever possible way, has just one hit in his last 25 plate appearances dating back to May 5 and is hitting .133 on the season. Wilson Valdez gets the start at short and will hit second for a second-straight game, so it appears that Dobbs, who was once this team's top reserve, has moved to the very end of the trough.
