The Yomiuri Giants demanded Wednesday that free-agent infielder Toshihisa Nishi decide by Monday whether to re-sign with the Central League team or pursue a career in the major leagues, club representative Hidetoshi Kiyotake said.

Kiyotake said the deadline was set during talks with Nishi's agent, lawyer Masataka Uesugi, after he made clear Yomiuri's hopes that the 33-year-old will remain with the Tokyo ballclub.

"If he intends to stay with the team, we would like to offer him financial terms quickly," Kiyotake said, adding that negotiations would have to be terminated after Monday's deadline, depending on Nishi's response.
