Jimmy Nelson gives up six walks as the Milwaukee Brewers lose at home to Saint Louis 6-4 on Sunday. Nelson walked three batters in the fourth inning, when the Cardinals scored three runs to put the game away./ Winning pitcher Mike Leake helped his own cause with a two run single in that frame, and he improved to 3-1 by striking out six in six innings while giving up two runs on three hits — the first time all year that Leake gave up more than one run, as he came into the game as the National League’s E-R-A leader./ Nelson surrendered four runs and fanned five in five and one third innings — and he fell to 1-1 on the year and 0-8 lifetime against Saint Louis. Manny Pina hit the game’s only homer for Milwaukee, which has now lost five of its last six games and will host Cincinnati tonight.
