Oakland Athletics (1969–76) Tenace was selected in
baseball's first entry draft, being taken in the 20th round of the
1965 Major League Baseball draft by the then
Kansas City Athletics. Tenace made his major league debut for Oakland on May 29,
1969, against the
Detroit Tigers at
Oakland–Alameda County Coliseum where he went 0-for-4 with two
strikeouts in an 8–4 Oakland loss. He hit the first
home run of his career on June 6, 1969, at
Tiger Stadium against
Earl Wilson of the Detroit Tigers. He finished the season with a .158
batting average, a home run and two
runs batted in, appearing in just 38 games as a third-string catcher. Tenace entered the
1972 season backing up Duncan, but was given a chance to show his abilities by being made the team's regular catcher in the post-season. Tenace took full advantage of this opportunity, excelling in the 1972 playoffs and World Series. In the
1972 American League Championship Series against the
Detroit Tigers, he drove in the clinching
run in Oakland's 2–1 victory in Game 5; it was his only hit of the series. Tenace's heroics made up for an error in Game 4 of the series when he had to play second base (for the first time since high school) in the late innings due to regular second baseman
Dick Green getting hurt and backup second baseman
Ted Kubiak having to play shortstop due to
Bert Campaneris being suspended. Tenace dropped a throw from
Sal Bando on a potential game-ending double play attempt in the bottom of the 10th which kept the inning alive as the Tigers eventually won. He put himself in the spotlight once again in Game 1 of the
1972 World Series when the Athletics faced the
Cincinnati Reds. He became the first player to hit home runs in his first two World Series
at bats and drove in all three runs in the A's 3–2 victory. Prior to Tenace's feat, only eight other players had homered in their first World Series at bat. In Game 4, the A's were losing 2–1, with their only run to that point coming on Tenace's solo home run. A ninth-
inning one-
out rally consisting of four
singles, with Tenace's the second and the rest coming from
pinch hitters, won the game against Cincinnati's ace
relief pitcher,
Clay Carroll. He hit a three-run
home run in the A's Game 5 loss. Before Game 6 of the 1972 Series, he was the target of a death threat; an intoxicated Reds fan tried to enter the game with a loaded gun in his pocket, threatening to shoot Tenace if he hit another home run. In Game 7, he was once again the hero, driving in two runs in a 3–2 victory for Oakland. In total, he went 8-for-23 in the Series, with four
home runs and 9 RBI to earn the
World Series Most Valuable Player Award. Tenace's heroics helped him earn a full-time job in Oakland's lineup. He served as the team's starting
first baseman for two seasons, while still serving as the backup catcher to
Ray Fosse. He had his roles reversed in , starting at catcher while backing up first base. As a regular starter for the A's, Tenace had a low
batting average but a fair amount of power, hitting 20 home runs in four consecutive years in Oakland, finishing among the top 10 home run hitters in the
American League each year. He further made up for his lack of a high batting average by sporting a tremendous batting eye. He drew over 100
walks in a season three times for Oakland, and led the American League in
walks in 1974, making up for a career-low .211 average that year. Statistically, his best year with Oakland was in
1975, when he hit a career-best 29 home runs and drove in 87 runs, drew 106 walks, finished 18th in the American League
Most Valuable Player Award balloting and was selected to be the starting first baseman for the American League in the
1975 All-Star Game. As a member of the A's, Tenace hit what turned out to be the final home run in the history of Kansas City's
Municipal Stadium on September 30, 1972, in a 10–5 Oakland victory over the
Kansas City Royals.
San Diego Padres (1977–80) Tenace was one of several Athletics who became
free agents after the
1976 season and participated in a newly created re-entry draft, in which teams acquired the rights to negotiate with veteran free agents. Tenace and teammate
Rollie Fingers were the first players from that draft to sign, with both joining the
San Diego Padres in December of that year. In four years as a starter with the Padres, his power numbers dropped in part due to the cavernous dimensions of San Diego Jack Murphy Stadium, only reaching 20 home runs once; but his batting eye remained, recording three more seasons of 100 walks, with a career best of 125 in
1977. In
1979, Tenace led
National League catchers with a .998
fielding percentage, committing only one
error in 94 games. He recorded an
on-base percentage of over .390 in each of his years in San Diego, and finished third in the National League in that department in three consecutive years.
St. Louis Cardinals (1981–82) After the
1980 season, Tenace, Fingers,
Bob Shirley, and
Bob Geren joined the
St. Louis Cardinals in a trade for
Terry Kennedy and six minor league players.
Pittsburgh Pirates (1983) Tenace played his final season as a
utility player and pinch-hitter, appearing in 53 games and batting just .177 with 6 RBI for the
Pittsburgh Pirates in
1983. He retired after being released the following year in
spring training. ==Coaching career==
