The Milwaukee Brewers will promote top pitching prospect Jimmy Nelson to start against the St. Louis Cardinals on Saturday.

Nelson is 10-2 with a 1.46 ERA in the minors with 114 strikeouts and 32 walks in 111 innings. He made one start for Milwaukee last month, earning his first Major League win against the Miami Marlins.

The Brewers are bumping Marco Estrada from the starting rotation.
