The 34-year old left-hander pitched two scoreless innings and worked out of jams during both frames Friday in the Braves' 5-4 loss to the New York Yankees.
"I wouldn't say I'm there yet, but I feel like I'm getting better and better, and that's the progression I would like to have," Kazmir said.
Kazmir is 108-96 with a 4.01 ERA over 12 seasons. He didn't pitch last year.
"Fell behind a lot of guys but was able to make some pitches to get some outs," Kazmir said.
Tyler Wade hit an inning-ending grounder in the second, leaving a runner at third.
