The Braves officially announced the signing via release:
The 6-foot-4, 205-pound native of San Diego, Calif., joined Chicago just prior to the 2018 trade deadline. The lefty has also pitched for Philadelphia (2006-15) and Texas (2015-18) in his 14-year career. Hamels has made four All-Star teams and was both the NLCS and World Series MVP for the 2008 Phillies. He has a career 3.41 ERA (38 ER/100.1 IP) in 17 postseason appearances, 16 of which were starts.
In his regular-season career, Hamels has made 421 starts and has 2,558 strikeouts in 2,694.2 innings, totals that are all the most among active left-handers. Hamels also ranks third among active southpaws in wins (163) and fifth in ERA (3.42).
Hamels was originally selected by Philadelphia with the 17th overall pick of the 2002 First-Year Draft out of Rancho Bernardo High School in San Diego.
