Kazmir, 37, is attempting to make his first appearance in a major league game since 2016, with sources saying the lefty's fastball velocity reached 92-93 mph in his most recent bullpen session.
Kazmir went 10-6 with a 4.56 ERA in 26 starts for the Los Angeles Dodgers in 2016, but missed the entire 2017 season because of a hip injury. He was traded to the Atlanta Braves ahead of the 2018 season, but his comeback bid fell short when he failed to win the No. 5 spot in the Braves' rotation coming out of camp.
A three-time All-Star, Kazmir is 108-96 with a 4.01 ERA over 12 seasons.
