伊良部秀輝
The Hokkaido native was 5–5 with a 3.89 ERA in 2003, whiffing 83 in 74 innings and being named an All-Star again. He pitched in 66 games, leading the CL. When Takatsu left for the Chicago White Sox, the 24-year-old was handed the Swallows' closer job. Igarashi went 5–3 with 37 saves and a 2.66 ERA in 2004. He held opponents to a .210 average and struck out 86 in 74 1/3 IP. He led the CL in both saves and appearances (66). He made the All-Star team for the fourth time. He won the Fireman of the Year Award, which Takatsu had taken three times. Along with Hirotoshi Ishii, he was known as one of the "Rocket Boys", noted for their fastballs in the mid-90s. On June 3, he threw a 158 km/h (98 mph) fastball, tying the Nippon Professional Baseball (NPB) record for fastest pitch ever (held by Hideki Irabu and Kazuo Yamaguchi); Igarashi would hit that figure several more times in his career. The record didn't even last a year as Marc Kroon broke it in May 2005. He still holds the record for the fastest pitch in an All-Star game, at 157 km/h.
