First things first for Houston Astros first base prospect Jon Singleton.
He's scheduled to join the major league club for the first time Tuesday — but today, the powerful 22-year-old agreed to a contract that's historic in that he got an extension before making his big league debut.
Sosnick Cobbe Sports, the agency that represents Singleton, confirmed in a tweet Singleton will be promoted in what it called an "historic deal."
Yahoo Sports, which first reported Singleton's promotion, said the deal guarantees Singleton $10 million, and the deal could be worth $30 million over eight years. The back end of the deal includes three team options, which would buy out one potential year of free agency and put Singleton on the open market at age 30.
The Astros have yet to make an official announcement of either the contract or the call-up, but a person familiar with the organization's plans confirmed Singleton is scheduled to join the team in time for Tuesday's home game against the Los Angeles Angels.
The person spoke to USA TODAY Sports on condition of anonymity because the club has not announced his promotion.
He'll move into a lineup recently rejuvenated by outfielder George Springer, another of the rebuilding team's collection of what they hope will become core players. Springer last week became the first rookie in 77 years to hit seven home runs in seven games.
But Springer also recently rejected a similar contract overture from the Astros.
Singleton, acquired from the Philadelphia Phillies in 2011 in a trade for Hunter Pence, is batting .267 with 14 homers and 43 RBI in 54 games at Class AAA Oklahoma City this season. He hit just .230 with 11 homers last season after being suspended the first 50 games for a violation of baseball's drug policy.
He admitted in spring to having battled a marijuana addiction.
Locking up players with little service time has been a trend gathering steam in the major leagues since 2008, when the Tampa Bay Rays signed Evan Longoria to a deal guaranteeing him $17 million just two weeks into his major league career.
