'''Dagoberto Campaneris Blanco''' (born Pueblo Nuevo, Kansas City and Oakland Athletics. One of the mainstays of the Athletics' championship teams of 1971 to 1975, he holds the A's franchise records for career hits (1882) and at bats (7180). After leading the AL in stolen bases six times from 1965 to 1972, he retired with the seventh most steals in history (649); he also held the Athletics' career record from 1972 to 1990. He led the league in putouts three times, and ended his career among the major league leaders in games (5th, 2097) and double plays (7th, 1186) at his position. He hold the record for most errors since 1940, with 388. His cousin José Cardenal was a major league outfielder for 18 seasons.

A small, skinny player at 5 ft 10 in (1.78 m) and 160 pounds (73 kg), the Cuban-born Campaneris was a key figure on the A's of the 1960s and 1970s, adding his fiery temper, competitive spirit and superb play to the team; he was also a daredevil on the basepaths. In his debut with Kansas City on July 23, , Campaneris belted two home runs, the first coming on the first pitch thrown to him by Jim Kaat. He is one of three players in major league history to hit two homers in his first game; Bob Nieman () and Mark Quinn () are the only others to accomplish this feat.

On the mound, he pitched ambidextrously, throwing lefty to left-handers, and switched against right-handers. Since then, Twins, ), Rangers, ) and Tigers, 2000) have joined this select list of nine-position players in a major league game. Also in 1965, Campaneris led Kansas City in triples (12) and stolen bases (51), the latter mark being the highest total by an Athletic since Most Valuable Player award after having a similar season at the plate, but playing more regularly at shortstop.

When the A's moved to Oakland in , he had perhaps his finest year, leading the league in hits (177), steals (62), and at bats (642); the last mark was an Oakland record until runs batted in while leading the league in steals for the fifth time (42) and scoring 97 runs. He improved consistently on defense; his six double plays in an extra-inning game on bunter, he led the league in sacrifice hits in 1972 (20),  (40) and  (25).

In his postseason career he had 11 RBI with 3 home runs, 4 doubles and a triple, scored 15 runs, and stole 6 bases in 37 games. In Game Two of the World Series win over the Cincinnati Reds.

In the won Game 3 with a leadoff home run in the 11th inning; in Game 7 of that year's World Series against the New York Mets, he hit a 2-run homer in the third inning off Jon Matlack—the first of the only two home runs Oakland would hit the entire Series. Reggie Jackson hit the other, also a 2-run shot in the same inning, giving Oakland an early 4-0 lead as the A's won the World Championship for the second straight year. In  he broke Jimmy Dykes' franchise mark for career at bats (6023), and in  he broke Dykes' mark for games played (1702), as well as Al Simmons' Athletics record of 1827 career hits.

After the 1976 season, he signed with the Texas Rangers, but he saw his playing timed reduced in 1978. In May 1979 he was traded to the California Angels, and he split time at shortstop over the next two seasons with Jim Anderson and second and third bases, and also as a pinch hitter and as a pinch runner, before retiring.

1960～70年代にかけてアスレチックスの中心選手として活躍した。1967年8月29日のクリーブランドとの試合では、'''『1試合3三塁打』'''という、1939年のベン・チャップマン以来となる記録を作っている。その後1972年～1974年のワールドシリーズ3連覇に貢献。アスレチックスの球団記録（1795試合出場、7180打数、1882安打、1472単打）を保持している。
