Antonelli received the highest signing bonus in history at that point, originally signing for $65,000 with the Boston Braves.
Antonelli caused controversy right away, as Braves Manager Johnny Southworth wasn’t too impressed with his pitching.
Boston's ace pitcher Johnny Sain, spoke out saying he thought Antonelli's huge bonus was way too much to be given out for an unproven pitcher.
Johnny Sain even threatened to walk out of training camp at one point, due to his displeasure with the situation. In any event, Antonelli debuted in 1948 pitching the minimum required innings for a bonus baby, within the rules of the time.
In 1949 he struggled as a rookie, appearing in 22 games overall (10 starts), going 3-7 with a 3.56 ERA. The next season, in 1950 he was 2-3 with a 5.93 ERA making twenty appearances.

Antonelli caught the attention of the New York Giants, who were wanting a left hander to head out their staff. They were willing to trade away one of their most popular players, 1951 playoff hero, Bobby Thomson to get him. The deal was made in February of 1954.
At first the Giants fans were furious at losing Thomson & did not take to well to Antonelli, who had been nothing more than a .500 pitcher at best. But that all changed real quickly, as Antonelli became one of the National League's best pitchers and the ace of a Giants staff that would go on to win the 1954 World Series championship.
Antonelli made his Giants debut in the third game of the season at Philadelphia, taking a tough 2-0 loss to the Phillies. He came back to win his next two starts, pitching two complete games, including a three hit shut out at the Polo Grounds against the same Phillies on April 25th.

Antonelli threw back to back shut outs at the start of June then again in September. On June 13th he allowed just one run & threw a three hit victory against the Chicago Cubs at Wrigley Field.
