Smith was a standout catcher for the Cardinals during his six years with them. He was the club's regular receiver from 1956 until his forced retirement. Before the 1957 season, Cardinal manager
Fred Hutchinson said "Hal Smith looks like a better catcher." He was selected a
National League All-Star in and . Smith led NL catchers in
throwing out would-be base-stealers in both 1959 and 1960, and in caught stealing percentage in 1960. On
Opening Day (April 11), 1961, with the Cardinals trailing the
Milwaukee Braves 1–0 going to the eighth inning, Smith got the team's third hit of the game against
Warren Spahn, a leadoff triple. He scored on a
Bob Nieman single to tie the game, and the Cardinals eventually won 2–1 after
Daryl Spencer hit a home run in the 10th inning. On June 10, 1961, after starting 42 of the Cardinals' first 48 games—and shortly after he celebrated his 30th birthday—Smith complained of chest and upper abdominal pains. He was admitted to
Jewish Hospital, St. Louis, where he was diagnosed with a "coronary artery condition." Smith was forced to immediately retire from playing baseball, and was the Cardinals'
bullpen coach in 1962. His disability eventually cleared the way for
Tim McCarver to become the Cardinals' new regular catcher. Four years after his illness forced him to the sidelines, Smith was able to appear in four games in July 1965 for the Pirates as a player-coach on an emergency basis, when
Jim Pagliaroni,
Del Crandall and
Ozzie Virgil were injured. Smith started one game (July 1 against the Cardinals), and was a defensive replacement in his three remaining appearances, catching for 12 total
innings. He then returned to the coaching ranks on
Harry Walker's staff. In a seven-season career, Smith was a .258
hitter with 437
hits, including 63
doubles, eight
triples and 23
home runs and 172
RBI in 570
games. As a catcher, he appeared in 548 games and recorded 2,810
putouts, 247
assists, and only 33
errors in 2,890
total chances for a .989
fielding percentage. From 1956 through 1961, Smith was one of two
Hal Smiths catching in
Major League Baseball; the other,
Harold Wayne Smith, played for the
Kansas City Athletics (1956–59) and Pirates (1960–61). Since the Cardinals and Athletics were in two different leagues, the two did not play against each other until 1960, but they met for the first time in 1957 spring training. Smith is the subject of a biography,
The Barling Darling: Hal Smith In American Baseball, written by Billy D. Higgins. In 2003, McCarver ranked Smith third on a list of the Cardinals' greatest catchers, praising the player's defensive skills. "He could really catch, with soft, pliable hands, and he could throw lasers. He was a lot like
Jerry Grote on the Mets, who was the best defensive catcher I ever saw," McCarver said. "All pitchers loved Hal Smith." ==Personal life==
