HOUSTON (AP) -- Highly touted Houston Astros prospect Jon Singleton has agreed to a five-year contract and will make his major league debut on Tuesday.
First baseman Marc Krauss, a Patrick Henry High School graduate, was sent to Triple-A to make room for Singleton. Krauss was hitting .173 with four homers and 14 RBIs.
The Astros announced the deal and his promotion Monday during an off-day. Houston hosts the Los Angeles Angels on Tuesday night.
Singleton is rated by many as baseball's top first baseman of the future. His new deal runs through the 2018 season with club options for the following three seasons. Financial terms weren't disclosed.
