The St. Louis Cardinals have a complete team, with an enviable lineup and full starting rotation, which made them one of the weirdest teams to peg at the deadline. They did need a reliever, though, and that's exactly what they targeted, making a deal with the Miami Marlins:

Cards got Edward mujica for Zachary Cox

— Peter Gammons (@pgammo) July 31, 2012

Mujica went from the Padres to the Marlins in the Cameron Maybin deal before the 2011 season, and the 28-year-old right-hander has pitched 39 innings this year with a 4.38 ERA, 26 strikeouts, and 9 walks. The strikeout-to-walk ratio is down from where it's been the last three years, as Mujica's calling card is usually his plus-control. He also has a problem with home runs, though. How much of a problem?

Edward Mujica has 50 career home runs allowed and 46 career unintentional walks

In two seasons in San Diego, the reliever allowed 28 home runs. Read that sentence again.

Zack Cox was the 25th-overall pick by the Cardinals in the 2010 draft. He entered the year as the #88 prospect in baseball according to Baseball America, but the 23-year-old has struggled mightily in the Pacific Coast League this year, hitting just .254/.294/.421.
