Chase Anderson pitched seven shutout innings as the Milwaukee Brewers edged the Mets Thursday afternoon 2-1.  That gave the Central Division-leading Brewers a split of the four-game series.  The tight contest was highlighted by a collision between Mets infielder Wilmer Flores and a bat boy on a foul pop.  The bat boy interfered, but M-L-B rules say that isn’t an out because he was already on the field.  New York manager Terry Collins was ejected for arguing.  Nick Franklin slapped an R-B-I-single and tossed a runner out at the plate.  Hernan Perez knocked in the other run.  Anderson held the Mets to three hits and a walk while picking up his fourth win.  Jimmy Nelson starts for Milwaukee tonight as the Brewers begin a seven-game home stand.
