Jimmy Nelson's fantasy impact

The Milwaukee Brewers have been one of the most pleasant surprises in baseball this season, in large part thanks to their pitching, with four starters who have kept the Brewers in games as well as any rotation in the National League.

That pitching staff now looks to be even stronger, as Milwaukee has called up their top prospect in Jimmy Nelson to take the place of the struggling Marco Estrada in the rotation. Nelson has been among the most dominant pitchers in minor league baseball, with an ERA of 1.46 and 114 strikeouts in 111 innings for Triple-A Nashville this season.
