EDGE Analysis

Stone got knocked around again Sunday against the Rays and has now surrendered 17 runs -- 16 earned -- through his first three major-league starts covering just 10 innings. Alex Vesia will join the Dodgers' bullpen Tuesday in a corresponding roster move, with Michael Grove (groin) lined up to fill the rotation vacancy next weekend versus the Yankees.
