Jimmy Nelson will replace Marco Estrada in the Brewers' rotation on Saturday against the Cardinals. The writing had been on the wall, as Estrada has continued to struggle with the longball while Nelson dominated at Triple-A Nashville. The 25-year-old has put up a 1.46 ERA, 0.92 WHIP, and 114/32 K/BB ratio over 111 innings this season at Nashville and is worth gambling on in all fantasy formats.
