Former Top Prospect Jon Singleton Released by Astros During Drug Suspension

The Houston Astros released Jon Singleton amid his 100-game suspension for violating the MLB's substance-abuse policy a third time, according to ESPN.com.

Singleton, 26, was considered Houston's top prospect in 2011 by Baseball America. But he failed drug tests in both June and December 2012 before failing a third test this past January. He hasn't played in the Major Leagues since 2015.

In his MLB career, Singleton hit .181 with 14 home runs and 50 RBI in 114 games between the 2014-15 seasons. He signed a five-year, $10 million extension with the Astros in 2014.

Last year for the AA Corpus Christi Hooks, he batted .205 with 18 homers and 62 RBI in 117 contests.

In 2014, Singleton acknowledged his issues with marijuana use.

"I knew I had a problem," he told the Associated Press, per ESPN. "Even after I failed the second drug test, I couldn't stop smoking weed. It was really bad. Me going [to the rehab center] was definitely the best move."

He has also acknowledged abusing alcohol in the past to deal with depression.

"A little bit, yeah, (with marijuana), but more or less the alcohol," he told the Houston Chronicle in 2014. "And I wasn't being successful in 2013, and I was looking for an escape."
