Smoltz is open to starting or relieving and could serve in the closer's role for a team in need of help at the back of the bullpen. Astros general manager Ed Wade said late on Tuesday that he wasn't going to comment on Smoltz.
Astros closer Jose Valverde and setup man LaTroy Hawkins are both free agents, and Houston would be forced to find a closer if both leave. It just doesn't appear it will be Smoltz, who went 2-5 with an 8.32 ERA for the Red Sox last year, before going 1-3 with a 4.26 ERA in seven starts for the Cardinals.
According to the report, the Cardinals, Dodgers, Mets and Mariners are among the teams that have expressed preliminary interest in the 42-year-old Smoltz.
