Hickman played 624 games with the Mets, from 1962 through 1966. He batted.241 with 60 home runs and 210 RBI. Hickman has earned several places in Mets history. He was the first Met to hit for the cycle, accomplishing the feat in a 7–3 victory over the St. Louis Cardinals at the Polo Grounds on August 7, 1963; it is one of the few natural cycles in Major League history. A month later, on September 18, he hit the last home run ever hit at the Polo Grounds, a solo against Chris Short of the Philadelphia Phillies in a 5–1 Mets' loss, in the final game ever played at that stadium. Hickman was also the first Met to hit three home runs in one game, at Sportsman's Park on September 3, 1965, in a 6–3 victory over the Cardinals. All three home runs were hit off Ray Sadecki. Finally, he was the last of the original Mets, when he was traded to the Dodgers for outfielder Tommy Davis on November 29, 1966. Hickman also set a pair of Shea Stadium firsts, earning the team's first walk and first batter hit by pitch, both accomplished in the team's inaugural game at the stadium, a 4–3 loss to the Pittsburgh Pirates on April 17, 1964.
Los Angeles Dodgers
Hickman spent 1967 with the Dodgers, batting just.163 in 65 games played, with no home runs and 10 RBIs.
Chicago Cubs
In April 1968, Hickman was traded to the Cubs. During the 1968 season he hit.223, and in 1969 he hit.237. Hickman then had his best season in 1970, when he hit.315 with 162 hits, 33 doubles, 32 home runs, 115 RBIs, 102 runs scored, and 93 walks — all career highs. His performance won the National League Comeback Player of the Year Award and placed him 8th in the NL Most Valuable Player balloting. Hickman made his only All-Star appearance on July 14, 1970, at the Cincinnati Reds' newly opened Riverfront Stadium where, in the 12th inning, his RBI single drove in hometown favorite Pete Rose for the winning run, Rose barreling over Cleveland Indian catcher Ray Fosse to score the run. Like Hickman, the pitchers of record were also Tennessee natives; Claude Osteen, Hickman's Dodger teammate in 1967, was the winning pitcher, while Hickman collected the walk-off single off Clyde Wright, his eventual 1970 American League Comeback Player of the Year counterpart. In his six seasons with Chicago, Hickman batted.267 with 97 home runs and 336 RBIs in 682 games played.
St. Louis Cardinals
