Maeda (hamstring) has been officially activated from the disabled list ahead of Thursday's start against the Cardinals, Ken Gurnick of MLB.com reports.
The Dodgers placed center fielder Joc Pederson on the 7-day concussion DL to clear a roster spot for Maeda, who had been shelved with a hamstring injury. Maeda had his best start of the season prior to going on the DL, holding the Pirates to two earned runs over 8.1 innings. He'll face a St. Louis lineup that ranks 16th in MLB in wOBA in May.
