He was drafted four times by major league teams between 1970 and 1973 without signing. Smalley was selected by the Montreal Expos in the 35th round of the June 1970 draft, by the Boston Red Sox in the 4th round of the January 1971 draft, by the St. Louis Cardinals in the 2nd round of the June 1971 draft, and again by the Red Sox in the 5th round of the January 1972 draft. Smalley was the number one overall pick in the January 1974 amateur draft by the Rangers. Following his junior year, he stayed out of school in the fall of 1973 to be eligible for the January free agent draft.[3]
Professional career
Rangers
After signing in January, Smalley had wrist surgery in February, injured while playing semi-pro ball in December.[4] He was sent to the Pittsfield Rangers in the Double-AEastern League, hitting .251 with 14 home runs and 42 RBI. Following a brief stint with the Triple-ASpokane Indians in the Pacific Coast League, Smalley was promoted to the big leagues for good, seeing time in 78 games for the Rangers in 1975, despite hitting only .228 with 3 home runs.[5] Smalley started the 1976 season back in Texas, but did not improve on his 1975 average. On June 1, his career would take a major turn.
Twins
Under the ownership tenure of Calvin Griffith, the Minnesota Twins made few headlines in the transaction department, but Smalley's arrival and departure from the Twins both involved blockbuster trades. On June 1, 1976, Smalley was traded to the Twins, along with Texas infielder Mike Cubbage, pitchers Jim Gideon and Bill Singer and cash, for Twins' ace Bert Blyleven and shortstop Danny Thompson, who was battling leukemia.[6] Smalley was inserted into the Twins' starting lineup and manned shortstop until 1982. During his first go around with the Twins, Smalley developed into an all-star.
Smalley's best season came in 1979, when he was voted the starting shortstop for the American League in the All-Star game. Smalley had a sensational first half of the season, entering the break with the second-highest batting average in the major leagues (.341). Though he tailed off in the second half, Smalley established career highs in runs, RBIs, and home runs, and was named the shortstop on The Sporting News AL All-Star team. He also led the league in games played, plate appearances, all fielders in assists, and all shortstops in putouts,[5] while hitting .271 and leading the team with 24 home runs and 95 RBI. He did not build on this season with the Twins, as injuries struck, and he played only 133 games in 1980 and 56 in 1981.
Yankees and White Sox
After showing that he'd recovered from his injuries, Smalley was traded in 1982 on April 10 to the Yankees for pitchers Ron Davis and Paul Boris and shortstop Greg Gagne. With the Yankees, Smalley showed a glimpse of the player he had been in 1979, hitting 20 home runs in 1982 and 18 in 1983. He was not as good defensively, however. Yankee pitcher Tommy John thought he was best as a designated hitter. "He had no range at short. No range at all. He was bad news for a pitching staff," opined John, who had benefitted from the fine defense of Bucky Dent for the past several years.[7] John did note that Smalley was a much better hitter than Dent.[7] After a bad start to the 1984 season, in which he hit only .239 with 7 home runs and 26 RBI over the first 67 games of the season, Smalley was traded again, this time to the White Sox for middle reliever Kevin Hickey and future Pittsburgh Pirates Cy Young and 155-game winner Doug Drabek.[5]
Back to the Twins
Smalley was a member of Minnesota's 1987 World Championship team. He hit .275 with 8 home runs and 34 RBI in 110 games in his last major league season.
