HOUSTON — Touted Astros prospect Jon Singleton agreed to a five-year contract and will make his major-league debut tonight at home against the Angels.
Houston announced the deal and his promotion Monday during an off day.
Singleton is rated by many as baseball's top first base prospect. His new deal runs through the 2018 season with club options for the next three seasons. Terms weren't disclosed, but espn.com reported that he'll receive a guaranteed $10 million.
Singleton, 22, was hitting .267 with a stellar .397 on-base percentage and a .544 slugging percentage in 54 games for Triple-A Oklahoma City. Astros first basemen are batting a majors-worst .181 this season.
Singleton was acquired from the Phillies in the 2011 trade for OF Hunter Pence. He was suspended 50 games last season for a second failed drug test.
Singleton said in spring training that he has an addiction to marijuana and had spent a month in a rehabilitation center last year.
