A two-time All-Star, Hall made his debut with the Minnesota Twins (1963–66), followed by stints with the California Angels (1967–68), Cleveland Indians (1968–69), New York Yankees (1969), Chicago Cubs (1969–70) and Atlanta Braves (1970).

[1][2] After signing, Hall was assigned to the Superior Senators in the D-level Nebraska State League where he made an immediate impression-hitting .385 with 15 home runs, 6 triples, and 11 doubles in only 58 games.

[5] Hall also was given an extended tryout at shortstop (with the Senators typically only having all-field, no-hit options on the major league roster[6]), but he would struggle in the field at this new position and commit 24 errors in only 78 games.

[5] Although Hall would be promoted to the AAA Charleston Senators in 1960, he would hit only .227 with 9 home runs and 30 RBI in 110 games, in which he would see double digit starts at second, third, shortstop, and the outfield.

The 1961 and 1962 seasons saw Hall appear in only 54 total games spread over three AAA teams, the Syracuse Chiefs, Toronto Maple Leafs, and Vancouver Mounties, hitting a combined .232.

He is one of only two players in the modern era of major league baseball history, along with Dodgers outfielder Joc Pederson (2015), to have two streaks of home runs in four consecutive games or more in their rookie season.

[11] At the end of the season, he would finish third in the Rookie of the Year voting behind a pair of Chicago White Sox, third baseman Pete Ward and starting pitcher Gary Peters.

With 3 home runs off Kansas City Athletics reliever Dan Pfister and Killebrew's off his replacement, Vern Handrahan, the Twins would pull out a 7–3 victory.

[18] Hall immediately exited the game, but returned to the starting lineup about a week later and then played well for the remainder of the season while wearing a special protective flap on his batting helmet.

[24] His 1965 would basically be a carbon copy of the previous season and would see him hit career highs in average (.285), RBI (86), doubles (25), and stolen bases (14), but would also see another drop in home runs to 20.

[1][25] He would be named to his last all-star team in the July 13 game that was played at Minnesota's Metropolitan Stadium, along with five fellow Twins (first baseman Harmon Killebrew, catcher Earl Battey, pitcher Mudcat Grant, shortstop Zoilo Versalles and Tony Oliva), and went hitless with a walk and a run in two plate appearances after pinch hitting for pitcher Pete Richert in the bottom of the fifth inning and moving over to center field in place of starter Vic Davalillo to begin the sixth.

[26] Hall's struggles against lefties in 1965 (a .240 batting average) continued in that year's World Series against the NL champion Los Angeles Dodgers.

Deciding to employ the light-hitting Uhlaender full-time in center, the Twins traded Hall on December 2[28] to the Angels along with reliever Pete Cimino and first baseman Don Mincher for starter Dean Chance and a player to be named (which would become infielder Jackie Hernandez on April 10, 1967).
