Astros general manager Jeff Luhnow told CBSSports.com's Jon Heyman that he plans to have a scout watch Clemens pitch for the independent Sugar Land Skeeters on Sept. 7.
The strong speculation in baseball has been that if all goes reasonably well that night, Clemens will then pitch for the Astros five days later, on Sept. 12 against the Cubs.
The 50-year-old Clemens, who was recently acquitted of seven counts of obstruction and perjury in relation to his use of PEDs, signed a contract with the Sugar Land Skeeters last month. Clemens has made one start for the club, striking out two in three and a third scoreless innings last Saturday.
Several have speculated his return to baseball may be an attempt to delay his Hall of Fame eligibility so as to remove some of the stigma from his association with steroids. Clemens last appeared in the big leagues in 2007 and would be eligible for the Hall of Fame ballott this year unless he returns to the MLB, in which his eligibility will be delayed five years.
The Astros, for their part, are likely looking for anything to boost attendance and interest in the club. Owners of the worst record in baseball at 40-91, Houston has won just seven games since the All-Star break and attendance has taken a massive hit as a result.
