Timothy Lincecum is not yet ready to hang up his cleats.
Lincecum, who last pitched in 2016 with the Angels, has been working out with Rockies pitcher Adam Ottavino and is planning to "throw for teams at a showcase in the near future," according to Kyle Boddy of Driveline Baseball.

Boddy is the founder and president of Driveline Baseball, which is based in Kent, Wash., not far from Lincecum's hometown of Bellevue. On Tuesday, Boddy posted a picture taken by Ottavino of a beefed-up Lincecum on Twitter, notifying the baseball world that the three-time World Series champion is preparing to make a comeback.

Lincecum, 33, held a showcase in May 2016 after recovering from hip surgery and managed to land a deal with the Angels before allowing 41 runs (39 earned) in 38 1/3 innings across nine starts. He accepted an outright assignment to Triple-A Salt Lake City that August.
The right-hander won back-to-back National League Cy Young Awards with the Giants in 2008-09, and he was named a National League All-Star in four consecutive seasons ('08-11).
Lincecum is 110-89 with a 3.74 ERA in 278 Major League games (270 starts) while appearing in parts of 10 big league seasons.
It's possible that a team in need of pitching would offer him an invite to Major League Spring Training with a positive performance in his upcoming showcase. It is not yet known when that will take place.
