Jeurys Familia had a difficult time leaving New York, having spent his entire major league career with the Mets.
A victory in his Oakland debut made the transition a little easier. Familia pitched two scoreless innings, Marcus Semien scored from second base on Matt Chapman's infield chopper in the 10th inning and the host Athletics beat the San Francisco Giants 6-5 on Sunday.
"I felt good," Familia said via a translator. "I obviously wasn't used the last couple days but I felt really comfortable about coming in and doing the job today."
Familia was acquired Saturday in a trade for two minor leaguers and $1 million in international signing bonus pool allotment. The 28-year-old righthanded reliever arrived in Oakland about an hour before the game after catching a 7 a.m. flight.
He gave up a leadoff single to Austin Slater in the ninth but recorded six outs at after that, including an inning-ending double play in the ninth.
An All-Star in 2016, Familia was 4-4 with a 2.88 ERA and 17 saves with the Mets. In Oakland, he will split closing duties with All-Star Blake Treinen.
"What a great first look," A's manager Bob Melvin said. "When you come to a new team first impressions are important and when you pitch the way he did, it makes you feel like part of the team very quickly."
