Cash was born in Justiceburg, Garza County, Texas, and attended (what was then) Sul Ross State Teachers College, where he was All-Lone Star Conference in football as well as playing baseball; he was drafted by the Chicago Bears as a running back in 1955, but declined to play pro football. After signing with the Chicago White Sox in 1955, he spent 1957 in the military and made his debut with the team in 1958, seeing limited play as an outfielder and pinch hitter. He appeared in 58 games for the 1959 AL pennant-winners; the August 25 acquisition of Ted Kluszewski left him on the White Sox bench. He was hitless in four pinch-hitting appearances in the World Series. In December of that year, he was traded to the Cleveland Indians in an eight-player deal that brought Minnie Miñoso back to Chicago, but the Indians general manager Frank Lane traded Cash to Detroit for Steve Demeter, who would play only four more games; both Chicago and Cleveland were haunted by Cash for the next 15 years, as he won a batting title in 1961 and a World Series ring in 1968 wearing a Detroit uniform.

In between, Cash played winter ball with the Indios de Oriente club of the Venezuelan League during the 1958–59 season. As the league champions, the Indios represented Venezuela in the 1959 Caribbean Series, as Cash posted a .360 average (9-for-25) and led the tournament in home runs (2), RBI (11) and slugging (.680), while driving in six runs in a game – also a Series record – and earning MVP honors.

In 1960, Cash grounded into no double plays, the first American League player to accomplish that since league records on this stat were started in 1940.

He enjoyed his breakout season in 1961. He led the AL with a .361 average, and had 41 home runs (sixth in the AL), 132 runs batted in (fourth), 119 runs scored (fourth), 124 walks (second) for a .487 on-base percentage (first), and 354 total bases (second) for a .662 slugging average (second); but his season was overshadowed by the 61 home runs of Roger Maris, and teammate Rocky Colavito finished with more home runs and RBI. Still, his .361 average would be the highest by any major league player in the 1960s. The Tigers finished 101–61 for their best regular season record since 1934, and scored the most runs in baseball, though they finished second in the AL, eight games behind the New York Yankees; Cash was fourth in the MVP voting. In addition, Cash later admitted to using an illegal corked bat during the 1961 season, demonstrating how he had drilled a hole in his bats and filled it with a mixture of sawdust, cork and glue. His 1961 statistics turned out to be career highs which he rarely approached again – in later years, he never reached 100 runs or 100 RBI, and never batted above .283. His 118-point drop to a .243 average in 1962 was the largest ever by a batting champion.

On June 11, 1961, Cash became the first Detroit Tiger to hit a home run ball out of Tiger Stadium. Cash hit the ball over Tiger Stadium’s right field roof four times in his career.

Cash summed up his success as follows: “I owe my success to expansion pitching, a short right-field fence, and my hollow bats.” Later in his career, Cash claimed he used a corked bat in 1961, even showing Sports Illustrated how he made one.

On his own team, Cash was overshadowed by his future Hall-of-Fame roommate Kaline. While his batting average fell off sharply after 1961, Cash hit 30 or more homers four more times, and hit at least 20 in ten of the next eleven seasons. He was the only American League player to hit at least 20 home runs every season from 1961 to 1969. He also finished second in the league in home runs three times (behind Harmon Killebrew in 1962, Tony Conigliaro in 1965, and Bill Melton in 1971), with the Tigers finishing among the AL’s top three scoring teams every year from 1961 through 1968.

On June 27, 1963, he played an entire game at first base without a chance, as the Minnesota Twins won 10–6.[1]

In the 1968 World Series, Cash hit .385 (10-26) with one home run. With two out in the seventh inning of Game 7, Cash singled to start a three-run rally that broke a scoreless tie and propelled the team to its first title since 1945. He later hit a home run to give Detroit a 1–0 lead in Game 1 of the 1972 American League Championship Series, though the Tigers went on to lose the game and the series.

Cash was also noted for not ever wearing a batting helmet during his major league career, being one of the few veteran players who was permitted not to do so after helmets were mandated in 1971. Protective liners, however, were required to be worn inside their caps.

On July 15, 1973, as Nolan Ryan was working on his second career no-hitter, Cash went to the plate with two outs in the bottom of the ninth (after striking out his previous three at-bats), holding a table leg from the clubhouse instead of a regulation bat. The stunt drew immediate action by the umpire, who ordered Cash to use a legal bat. Cash popped out using a regulation bat to end the game. [2]

He was released by the Tigers in August 1974 after hitting .228 in 53 games.

Cash was a color commentator for ABC’s Monday Night Baseball in 1976, and for Tiger telecasts on ONTV pay-cable from 1981-83.

In October 1986, Cash drowned in an accident off Beaver Island in northern Lake Michigan when he slipped off a dock and struck his head. His body was discovered about 11 a.m. in 15 feet of water at Beaver Island. An autopsy later revealed that Cash had a blood alcohol content of 0.18 percent at the time of his death. He is buried in Pine Lake Cemetery, West Bloomfield, Michigan.

On April 23, 2005, the high school and Little League baseball field in Post, Texas were dedicated to Cash. He was inducted into the Texas Sports Hall of Fame in 2001.
