The Red Sox placed minor league righthander Chris Acosta on the restricted list, according to multiple major league sources.

Acosta, whom the Red Sox signed out of the Dominican Republic for a $1.5 million bonus in July 2014 based on a three-pitch mix that suggested the potential to start in the big leagues, went 1-4 with a 4.28 ERA, 22 strikeouts, and five walks in 33⅔ innings in the Dominican Summer League in his pro debut in 2015.

The next step for the 18-year-old would typically be an assignment with a short-season affiliate in the United States. However, according to the sources, Acosta got in trouble at the Red Sox’ extended spring training facility in Fort Myers, Fla. He left Florida for the Dominican without permission, resulting in the placement on the restricted list, which prevents him from pitching for another team or in another league. Since returning to the Dominican, he has not fulfilled the team’s request that he report to its Dominican academy.
