Date: August 22nd, 1965 - Giant Stadium
Marichal, the pitcher for the Giants that day had hit two Dodgers players and Johnny Roseboro, the Dodger catcher signaled to Koufax (the Dodger starter) to hit Marichal with the next pitch. Koufax ignored him and so Roseboro whipped the toss back to Koufax right by Marichal's ear. During the verbal argument that ensued, Roseboro whipped off his catchers mask and the players got in each other's faces. At some point during the argument, Marichal took a full on swing which connected with Roseboro's unmasked head causing him to fall to the ground. Um....needless to say, both benches cleared. According to reports, the game was delayed by 14 minutes as things were sorted out, Roseboro was helped to the dugout (and then to the hospital where he received 14 stitches), Marichal was ejected.
Honestly, when I read this, I was shocked. Juan Marichal was suspended for 9 days and fined $1,750 by Major League Baseball for hitting and injuring Johnny Roseboro with a bat. Roseboro missed a couple of days and was back in the lineup. Roseboro ended up filing a lawsuit against Marichal over the incident and it was reported to have been settled out of court for $7,000. Marichal went on to win 243 games as a pitcher and was inducted into the Hall of Fame in 1983. It's hard to believe Marichal received such a light penalty for such a terrible act. If that happened today, a player would risk being suspended for the rest of the season, if not banned from the game altogether. Interesting fact: this incident is still the only incident even in a major league game where a bat was used a weapon. A few years back it happened again in the minor leagues.
