Mario Soto

In a 12-season career, all for Cincinnati, he was 100–92 with a 3.47 ERA in 297 games, 224 of them starts. He had 72 career complete games and 13 shutouts. He allowed 1,395 hits, 667 earned runs, 657 bases on balls and struck out 1,449 batters in 1,730​⁄3 innings pitched. He also earned four saves (all during the 1980 season).

In 2001, Soto was inducted into the Cincinnati Reds Hall of Fame and Museum. He has also worked with the team as a pitching coach, helping several Reds pitchers develop a change-up. He currently works in the Reds' front office. Soto is credited as the person who taught Edinson Vólquez and Johnny Cueto their change-ups, which have been go-to strikeout pitches in their careers.

By 1986, Soto's performance had rapidly deteriorated due to shoulder injury. On April 29, 1986, against the Montreal Expos, Soto became the 11th pitcher in major league history to surrender four home runs in an inning.

On May 12, 1984, Soto came very close to throwing a no-hitter against the St. Louis Cardinals. However, with two out in the top of the ninth inning and the Reds up 1–0, outfielder George Hendrick spoiled the no-hitter with a game-tying solo home run. The Reds won the game for Soto in the bottom of the ninth, 2–1.

On May 27, 1984 against the Chicago Cubs at Wrigley Field, third baseman Ron Cey hit what was originally ruled a home run down the left field line. Believing the ball had gone foul, Soto and Reds manager Vern Rapp disputed the call, and during the argument, Soto shoved third-base umpire Steve Rippley, who had made the call. After conferring, the umpires changed their decision and ruled it a foul ball, drawing a protest from the Cubs. However, for shoving Rippley, Soto was ejected, prompting him to charge the field. Cubs coach Don Zimmer stepped in front of Rippley to prevent Soto from attacking the umpire, only to himself be tackled by Soto and (inadvertently) catcher Brad Gulden, which triggered a 10-minute brawl. Four days later, National League president Chub Feeney suspended Mario Soto for five games.

In 1983, Soto finished second in voting for the National League's Cy Young Award. Philadelphia's John Denny was the winner. Statistically, 1983 and 1984 were Soto's best seasons. He compiled a 35–20 record with a 2.92 earned run average and he established himself as the ace of the Cincinnati Reds' rotation. However, the Reds finished with losing records in both seasons.

Mario Melvin Soto (born July 12, 1956) is a former Major League pitcher, mostly as a starter, for the Cincinnati Reds from 1977 through 1988. He currently works in the Reds' front office.
