Professional career
;Arizona Diamondbacks organization Heading into the 2010 MLB draft, Loux was seen as a potential late-first round pick. Surprising many, the Arizona Diamondbacks drafted Loux with the sixth overall selection, agreeing to a pre-draft deal with Loux with a $2 million signing bonus. However, Loux failed his physical with the Diamondbacks due to a torn labrum and elbow damage that doctors felt might require ligament replacement surgery in the future. As a result, the Diamondbacks did not offer Loux a contract, as the franchise chose to take advantage of compensation rules that instead would grant them the seventh overall pick in the 2011 MLB draft if they did not sign Loux. ;Texas Rangers organization Though unsigned draft picks typically cannot begin their professional careers until the next season, MLB declared Loux a free agent in an unprecedented move. After throwing for scouts, Loux signed a contract with the Texas Rangers, receiving a signing bonus of $312,000. In an attempt to prevent this situation from happening again, the new collective bargaining agreement negotiated that winter by MLB and the MLB Players Association added clauses that included mandatory physicals for all top 200 prospects prior to the draft, and a rule that makes all future draft picks who fail a physical and do not receive an offer of at least 40 percent of the assigned value for that pick are to become free agents, with the team facing a reduction in the amount of money they can spend on their draft picks. The Rangers assigned Loux to pitch for the Myrtle Beach Pelicans of the Class A-AdvancedCarolina League during the 2011 season. With the Pelicans, Loux had an 8–5 win–loss record with a 3.80 earned run average in 21 games started. In 2012, with the Frisco RoughRiders of the Class AATexas League, Loux began the season with a 9–0 record and 2.20 earned run average. After finishing the season with a 14–1 record, a 3.47 ERA and 100 strikeouts, Loux was named the Texas League Pitcher of the Year. ;Chicago Cubs organization At the 2012 trade deadline, the Rangers acquired Geovany Soto from the Chicago Cubs for Jake Brigham; however, the Cubs were concerned about Brigham's health and agreed to the trade on the condition that if Brigham was unable to play, the Cubs would send Brigham back to the Rangers and acquire Loux and a player to be named later in his place. After the 2012 season, with Brigham experiencing an elbow injury, Loux was traded to the Cubs. Loux pitched for the Iowa Cubs of the Class AAAPacific Coast League in 2013. He suffered a shoulder injury and underwent Tommy John surgery, which forced him to miss the 2014 season. In 2015, Loux experienced an elbow injury after making three starts for Iowa, and was released on July 17. ;Independent baseball In 2016, Loux pitched in two independent baseball leagues. He pitched for the Laredo Lemurs of the American Association of Independent Professional Baseball, and for the Sugar Land Skeeters of the Atlantic League of Professional Baseball. Loux has not pitched professionally since 2016.
