Contract details are currently unknown.
Lincecum was reportedly deciding between three serious suitors. In addition to the Angels, these teams included the White Sox and Giants.
Lincecum held a showcase for teams on May 6. This was done to show that Lincecum was healthy after rehabbing from a hip surgery in 2015. Approximately 20 teams went to scout him.
The soon-to-be 32-year-old Lincecum pitched 76 1/3 innings with the Giants in 2015, posting a 4.13 ERA and a 60 to 38 strikeout-to-walk ratio over 15 starts. The Giants were interested in a reunion with him though only as a relief pitcher.
In Los Angeles, however, Lincecum will get an opportunity to start. The team has dealt with a plethora of injuries to their starting rotation, including the loss of Andrew Heaney and Garrett Richards to UCL injuries.
The team has been forced to turn to Jhoulys Chacin and Nick Tropeano in spite of these injuries. Lincecum, at the very least, will provide depth to a starting rotation that currently has the the fourth-highest expected FIP (xFIP) in the Majors.
Lincecum, at his best, won back-to-back Cy Young awards with the Giants in 2008 and 2009. He was known as one of the best young pitchers in baseball but since 2012 has not been able to pitch to the same excellence.
