Most eyes may be on Pimlico, but we have a full weekend of racing action at Arlington as well.

This weekend, Chicago Railbird looks at a trainer who always comes out of the gate guns-blazing at Arlington: Larry Rivelli.  He currently sits atop the trainer standings, and has a host of runners this weekend.  Chicago Railbird looks at three of the races in which he sends runners, including a top-flight filly and mare allowance Saturday as well as a pair of races on Sunday.

Head on over to ShapperDaCapper, read the latest Chicago Railbird, and discover some picks and longshots for Arlington this weekend!
