The five-time All-Star pitcher will become the 24th member of the prestigious fraternity when he is inducted on Saturday prior to Minnesota's game against Oakland.
"It's a perfect day," Pascual said. "I never had that great feeling like I have today. When they told me I was going to be a member of the Minnesota Twins Hall of Fame, that really killed me. I'm really happy about it."
Thirteen of Pascual's 18 big league seasons came with the Senators and Twins. He ranks second in franchise history in shutouts (31), third in strikeouts (1,885), fourth in innings pitched (2,465) and fifth in wins (145).
Pascual led the American League in strikeouts for three straight years from 1961-63 and became the Twins' first 20-game winner in 1962, which he called his best memory.
"I pitched in the last game of the season," said Pascual, who has been scouting Latin America for the Dodgers for more than two decades. "I beat the Orioles, 1-0. Lenny Green got on base and Harmon Killebrew drove in the first run, the only run of the game. So that was a great memory."
