Yuki Saito

I'll be honest, I knew Yuki Saito before I knew baseball, because that 2006 Koshien run was less a tournament than a national event, and the kid calmly dabbing sweat with a blue handkerchief on the mound basically broke the country's brain. That marathon duel against Masahiro Tanaka had no business carrying that much tension between two high schoolers, yet here we are still talking about it. He went on to be Waseda's ace, then turned pro carrying expectations nobody his age should have to lug around, and the pros were rougher to him than the legend was. What I respect is that he kept climbing the mound anyway, this stubborn kid from Ota in Gunma who refused to flinch. The career didn't match the hype, but say "handkerchief" and a whole generation lights up. That's its own kind of immortality.
