The NPB kicked off koryusen (interleague season) this week with the first round of games taking place in Pacific League stadiums on Tuesday and Wednesday.
Interleague play is in its fifth season in Japanese baseball and the Pacific League is looking to go 5-for-5 against the Central League in the format.
The PL has won the battle between the two leagues in each of the previous four seasons, compiling a combined 360-348-12 record against their CL rivals.
