Graveman (1-0) allowed one hit in a scoreless eighth inning to earn the win Thursday against the Astros.
Graveman was a candidate to serve as the White Sox's closer to begin the season, but he instead entered the game with the score knotted at 1-1 in the eighth frame. Reynaldo Lopez ultimately pitched the ninth inning to earn the save after Chicago grabbed the lead. It's unclear whether Lopez is locked into the closer role or if Graveman will also see some save opportunities in the absence of Liam Hendriks (illness).
