After three seasons in the Pirates'
farm system, in which he went 28–21 with a 3.57
earned run average, McBean made his major league debut on July 2, 1961 in the first game of a
doubleheader against the
San Francisco Giants at
Forbes Field. Entered a tied game, the first batter he faced,
Ed Bailey, reached on an
error by
second baseman Bill Mazeroski. A
double,
wild pitch &
single later, the Giants had plated two
runs. A four run eighth
inning by the Pirates spared McBean from taking the loss in his major league debut. In his next 6 appearances, McBean pitched 10.2 innings without surrendering a run, and earning the first two wins of his career. His first career start also came against the Giants on September 11. He allowed three
earned runs over nine innings, and left with the game tied for the no-decision. For the season, he went 3–2 with a 3.75 ERA & 49
strikeouts. McBean was converted into a full-time
starting pitcher in 1962, and won his first three decisions. He finished with a 15–10 record & 3.70 ERA over the full season. ==Latino All-Star==
