Sakaeguchi is a very friendly person, who often tries to set Mihashi at ease. When Abe and Mihashi have trouble understanding each other (due to Abe's short temper and loud manner of speaking, and Mihashi's stammering and nervousness) Sakaeguchi generally attempts to mediate, being able to understand both of their mannerisms. He attended the same middle school as Abe, and they both played in the Seniors league, although they weren't friendly at this time as they were in different classes and on different baseball teams. Under stress, Sakaeguchi is known to get diarrhea, a trait revealed to everyone by Abe, who noticed it during their high school entrance exams. As a batter, Sakaeguchi is exceptionally good at bunting and usually bats in the leadoff position.
