As 2010 started its Pacific League's end of season race between the Hawks, Lions and Marines, Sugiuchi hit a minor slump just as his team needed him most. Between August 21 and September 18, he had 4 winless games (2 losts, 2 no results). His next game on Sept 25 was at Sapporo against the Fighters, and was the Hawks last second game of the regular season. The Hawks needed a win to maintain their lead in the league against Lions. He faced off against Fighters' ace Darvish and both pitchers went the whole nine innings. In the end, Sugiuchi prevailed as Darvish gave up one run and he gave up none while striking out nine Fighters. A much relieved Sugiuchi then famously broke down in tears at the Hero's interview as he admitted that he finally delivered during the pennant race.
