ST. LOUIS — Roger Clemens thinks any talk about a return to the majors is premature.

The Houston Astros decided to check him out anyway.

General manager Jeff Luhnow said Tuesday the Astros sent a scout to look at Clemens and left-hander Scott Kazmir, who also plays for the Sugar Land Skeeters of the independent Atlantic League. Clemens is to make his first start on Saturday at home against Bridgeport.

Luhnow said he wasn’t sure whether Clemens was trying to make it back to the big leagues or just wanted to keep doing something he was very good at for a long time. Clemens earned about $160 million and won 354 games in a 24-year career with the Red Sox, Blue Jays, Yankees and Astros, but hasn’t pitched since 2007.

“I don’t know what he’s trying to do,” Luhnow said. “I think he just wants to get back on the mound and see how it goes. You’ve got to see how you feel and how you respond.”
