The deal was for Marty Brown to finish above 4th, but with the Carp losing against the Yokohama Bay Stars, they can now finish no better than 4th and that means Brown's managing career with the Carp is over at the end of the season.
The Hiroshima Carp are currently looking at Kenjiro Nomura as a possible candidate to take over the team next season. If Nomura takes over next season, he'll be the youngest manager in the NPB (he's currently 43).
Nomura was Hiroshima's number 1 draft pick in 1989. He won the stolen base title 3 times in his career and was selected for the Best Nine team 3 times. In 1995 he batted .315 with32 home runs and 30 stolen bases. And in 2005 he collected his 2,000 hit; he retired later that season.
