According to Henry Schulman of The SF Chronicle, the "Giants did not even discuss a trade for (Trevor) Hoffman, making it likely the Giants claimed him to block the Dodgers or Rockies from getting him." We heard that a trade was unlikely when the waiver claim was originally made.
"It didn't seem to get too much of a head of steam," said Hoffman.
As Schulman points out, if the move was in fact made to block other clubs from acquiring Hoffman, it could end up being significant. The Rockies, who lead San Francisco by just one game for the NL Wildcard, just lost closer Huston Street to right biceps tendinitis for the foreseeable future.
Hoffman, baseball's career saves leader with 584, is enjoying another tremendous season at age 41, pitching to a 1.71 ERA and a 0.98 WHIP in 42 IP.
