Catholic Priest: At the age of twelve, Thomas began a six year period where he began studying to become a Catholic Priest. He eventually passed up on the vocation because he loved baseball too much. His mother was upset & his father as well. By high school was playing baseball on the Canadian side of Niagara Falls.
Even as a ball player Thomas, never drank, gambled or smoked, instead chose to spend his free time with his family. At six foot three, 200 lbs Thomas was a big man for his generation of ball players.
Thomas had tremendous power & could hit a baseball ball a long way. Big Frank was also very strong, he became famous for challenging people to throw a baseball their hardest at him, and he would dare to catch it with his bare hand. He claims to never have lost one of those bets.
He was nicknamed “the Big Donkey” because of his awkwardness, but was still very versatile on the field, usually playing outfield but he also played the infield when needed.
Thomas got signed by the hometown Pittsburgh Pirates in 1947 and hit 14 HRs for three straight minor league seasons. In 1951 he got better belting 23 HRs at AAA New Orleans, followed by a Southern league leading 35 HR season there in 1952, as he hit .303. Big Frank had arrived in the majors for good by 1953, after brief appearances in the 1951 & 1952 seasons.
There were high expectations for the big Thomas when he arrived with the Pirates in 1953, especially after they had just suffered one of the worst seasons in baseball history, going 42-112.
The expectations were so big that the team traded away the popular slugger & future Hall of Famer Ralph Kiner.
Thomas did not disappoint, winning over the fans as he hit 30 HRs (7th in the league) and drove in 102 runs, batting .255. He was the only Pirate to have hit double figures in HRs that season. In 1954 he led all NL outfielders in assists (14) & was second with a .989 fielding %.
Over the next six years in Pittsburgh, he made three All Star teams, hitting 23 or more HRs every season, including 30 plus HRs twice. He batted over .280 four times, & hit .290 or better twice, including a career high .298 in 1954.
In the New York Giants last home game at the Polo Grounds in 1957, it was Thomas who made the last put out.
In 1958 he had his best season, hitting 35 HRs with 109 RBIs (both second best in the NL). He posted career highs in double (26) hits (158) & batting average (.281). He earned 43% of the MVP voting, getting some celebrity status, even making the cover of Sports Illustrated in July 1958.
It was the only season while playing in Pittsburgh that his team didn’t finish near the bottom of the standings. The Pirates finished in second place to the reigning World Champion Milwaukee Braves that year.
After the season ended he was traded to the Cincinnati Reds with Jim Pendelton & Johnny Powers, for catcher Smokey Burgess, Don Hoak, & Harvey Haddix, who all became key to the 1960 Pirates World Championship team.
In 1959 Thomas was limited to 108 games, but still hit 12 HRs with 18 doubles & 47 RBIs before being traded to the Cubs at the end of the season.
He hit twenty plus HRs the next two seasons as well, splitting time in 1961 between Chicago & the Milwaukee Braves. That season he had hit 27 HRs (9th in the league) with 18 doubles 73 RBIs & a .281 average, his best batting average in three years.
In November of 1961 he was Traded to the expansion New York Mets for a player to be named later which turned out to be Gus Bell, and cash.
Mets Career: Frank Thomas became an original Met and it is safe to say, the team’s first true hitting star. Being a pull hitter, The Polo Grounds was a perfect fit for Thomas. He had the best year by far, of anyone on the team & was the team’s first cleanup hitter.

Quotes: Thomas enjoyed his time playing in New York- "We had a great ball club. We just didn't have any pitching. We scored a lot of runs but we lost a bunch of games in the seventh, eighth and ninth innings. If we could have had a closer like they have today, we might have been in the thick of a pennant race. It was great playing in New York. I really enjoyed playing for Casey Stengel. I've always said that he probably forgot more baseball than I'll ever know."
