"I did it last year, too, and I didn't like it," Aoki said through an interpreter prior to the Giants' DH-less game in Cincinnati on Thursday night. "I like to field."
Aoki went 0-for-3 with a walk on Tuesday against the Astros while leading off as the DH. He played in the Japanese Central League, which does not use the DH, from 2004 to 2011 before signing with Milwaukee in January 2012.
Posey was given the DH role on Wednesday as a way to keep his bat in the lineup while giving his catcher's knees a day of rest. He responded by going 3-for-5 with a home run and driving in three runs.
Posey laughed when asked if life as a DH might not be a bad way to go later in his career.
"Well, I'm going to be in the National League for at least the next seven years," said Posey, who signed a nine-year contract in 2013. "I tend to be up and down more when I'm sitting on the bench in those games, but that's about the only difference. To be honest with you, I don't really have a formula for it."
