"I want to be here," Mota said. "I have too much fun here. I want to come back."
After hearing Mota's comeback plan, San Francisco manager Bruce Bochy said: "That's what he told me. I said, 'Well, we're a little strapped in the 'pen tonight if you want to get ready.' He actually mentioned maybe trying to throw next year."
Mota spent three seasons with the Giants from 2010-12, compiling a 3-6 record with a 4.18 ERA in 155 innings. He pitched 2 1/3 scoreless innings in the 2010 World Series and gave up four earned runs on six hits in 1 2/3 innings during the 2012 playoffs.
In May 2012, Mota was suspended 100 games after testing positive for a performance-enhancing substance for the second time in his career.
Mota was greeted warmly by several Giants players, including Hunter Pence. Bochy said having the reliever back in the clubhouse on Saturday was nice.
"He got his ring," Bochy said. "He was really excited, pumped about it. The guys were excited about seeing Mota. ... They've had a good time revisiting."
Asked if he preferred his new World Series ring to his first, Mota was quick to respond, "Oh yeah."
