With the trade of starting pitcher Shelby Miller to the Braves on Monday, the deal should clear a spot in the Cardinals' rotation for pitcher Carlos Martinez, according to the USA Today.
Martinez spent most of the 2014 season in the Cardinals' bullpen, but he did make seven starts, going 2-1 with a 4.45 ERA. Overall, he was 2-4 with a 4.03 ERA in 57 appearances.
Martinez was an elite starting-pitcher prospect in the minors. He was considered a top-40 prospect by Baseball America from 2012-14.
