OAKLAND, Calif. (AP) — Sonny Gray struck out six and didn’t walk a batter over six scoreless innings to beat his former club with career win No. 100, and Willson Contreras doubled twice and drove in a run for the St. Louis Cardinals in their 3-1 win against the Oakland Athletics on Monday night.

Nolan Arenado hit an RBI single in the first to stake Gray (2-0) to an early lead against an Oakland team that had won three of four and drew a crowd of 5,508.

With the A’s set to play the next three seasons in Sacramento, Gray realized this was likely his last time taking the Coliseum mound. He earned his first career win here on August 15, 2013, against the Astros.

“I’ve made so many starts here and just knowing the whole week that this is probably the last one that you’ll have, probably the last time we’ll ever play here, it was pretty special,” he said. “To me, it had a lot more meaning than just a game in the middle of whatever month it is.”
