The Pacific League met last week to discuss the Central League's suggestion to cut down the number of Inter-league games from twenty-four to eighteen (per team). The PL does not want to see a reduction in games and in turn countered with several ideas to shorten the schedule that included splitting the Inter-league season into two halves that are played during the first and second halves of the regular season and a change to the way make-up dates are scheduled.
The CL met in Tokyo today and did not agree with the PL counter-proposal.
CL chairman (and Hiroshima Carp director) Kiyoaki Suzuki said to reporters, "Inter-league games currently make up a fairly large portion of the season games. Inter-league games should not influence the pennant race. ... Realistically, [the PL's proposals] are not possible."
The matters will be re-visited during an executive committee meeting in May.
UPDATE 4/25 @ 2:59pm -
Nikkan Sports has a bit more: the CL is reportedly against the twenty-four game format because they are questioning the need of the Inter-league season or an Inter-league champion.
"This is not just about the number of games. We need to think about what the Inter-league season means. There is a need for us to figure out the problems and discuss them," said Suzuki.
