"The Freak" may not possess the same caliber of stuff he used to earn two Cy Young awards early in his career, but right-hander Tim Lincecum is still drawing interest from teams, including his former Bay Area club.
Heyman cites an observer who said Lincecum was spotted pitching at the Giants spring training complex in Arizona and recently hit 90-91 mph during a dust storm.
The 31-year-old is close to a full recovery from September hip surgery and could slot into the Giants' bullpen, a role he's had brief experience in during his career, making seven relief appearances in 2014.
Lincecum made 15 starts for the Giants last season, notching a 4.13 ERA and 1.48 WHIP in 76 1/3 innings of work.
Over the course of his nine years in the bigs, the four-time All-Star owns a record of 108-83 with a 3.61 ERA, while striking out 9.3 hitters per nine innings.
