In baseball, the designated hitter rule is the common name for Major League Baseball Rule 6.10, an official position adopted by the American League in 1973 that allows teams to designate a player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher each time he would otherwise come to home plate, rather than letting the pitcher bat. Since then, most collegiate, amateur, and professional leagues have adopted the rule or some variant; MLB's National League and Nippon Professional Baseball's Central League, are the most prominent professional leagues that do not use a designated hitter.

Ronald Mark Blomberg (born August 23, 1948, in Atlanta, Georgia), nicknamed Boomer, is a former Major League Baseball designated hitter, first baseman, and right fielder. He played for the New York Yankees (1969, 1971–76) and Chicago White Sox (1978), and he was the manager of the Bet Shemesh Blue Sox in the Israel Baseball League (2007). He was the first designated hitter in Major League Baseball history.

He batted left-handed, and threw right-handed.

In his 8-season career, Blomberg compiled a .293 batting average (391-for-1,333) with 52 home runs, 224 RBIs, 184 runs, 67 doubles, and 8 triples in 461 games. He added a .360 on base percentage and a .473 slugging average. For his career, he hit .304 against right-handers, and .304 with 2 out and runners in scoring position, as well as .325 when the score was tied.

Blomberg attended Druid Hills High School, earning four letters each in baseball, basketball, and track, and graduated in 1967. He was an all-star in baseball, football, and basketball. He is the only athlete ever chosen for the Parade All-America teams in football, basketball, and baseball.

Thomas Charles Lasorda (born September 22, 1927 in Norristown, Pennsylvania) is a former Major League baseball player and manager. 2009 marked his sixth decade in one capacity or another with the Brooklyn/Los Angeles Dodgers organization, the longest non-continuous (he played one season with the Kansas City Athletics) tenure anyone has had with the team, edging Dodger broadcaster Vin Scully by a single season. He was inducted into the National Baseball Hall of Fame as a manager in 1997.

He was played by actor Arthur J. Nascarella in the ESPN mini-series The Bronx is Burning.

Tommy Lasorda signed with the Philadelphia Phillies as an undrafted free agent in 1945 and began his professional career with the Concord Weavers in 1945. He then missed the 1946 & 1947 seasons because of a stint in the United States Army. He served on active duty from October 1945 until spring 1947.

Adam Carolla (born May 27, 1964) is an American radio personality, television host, comedian, and actor. He hosts The Adam Carolla Show, a talk show distributed as a podcast which set the record as the "most downloaded podcast" as judged by Guinness World Records.

Carolla co-hosted the syndicated radio call-in program Loveline from 1995 to 2005 as well as the show's television incarnation on MTV from 1996 to 2000. He was the co-host and co-creator of the television program The Man Show (1999–2004), and the co-creator and a regular performer on the television show Crank Yankers (2002–2007). He hosted The Adam Carolla Project, a home improvement television program which aired on TLC in 2005 and The Car Show on Speed TV in 2011.

Carolla has also appeared on the network reality television programs Dancing with the Stars and The Celebrity Apprentice. His book, In Fifty Years We'll All Be Chicks, debuted on The New York Times Best Seller list in 2010.

Carolla was born in Los Angeles, California. His father, Jim Carolla, a psychologist of Italian heritage, and his mother, Kris (née Novello), who is of Hungarian descent, separated when Adam was young. Carolla was not given a middle name; on his driver's license application he filled the "middle name" blank with "Lakers" (after his love for the Los Angeles Lakers professional basketball team) and the made-up name still appears on his license.

Richard Alexander Burns (17 January 1971 – 25 November 2005) was an English rally driver. He was born in Reading, Berkshire. He was the 2001 World Rally Champion, having previously finished runner-up in the series in 1999 and 2000. He also helped Mitsubishi to the world manufacturers' title in 1998, and Peugeot in 2002. His co-driver from the 1991 to 2003 seasons was Robert Reid.

He started driving in a field near his house at the age of eight, in his father's old Triumph 2000. At eleven Burns joined the Under 17 Car Club, where he became driver of the year in 1984. Just two years later his father arranged a trip to Jan Churchill's Welsh Forest Rally School near Newtown, Powys where Burns drove a Ford Escort for the day, and from that moment on he knew what he wanted to do. He badgered his father into letting him join the Craven Motor Club in his home town Reading where his talent was spotted by rally enthusiast David Williams. In 1988 he entered his first rallies in his own Talbot Sunbeam. The car was too basic to make much impression and in 1989 he had to borrow other competitors cars in order to progress. To this end he rallied the stages of Panaround, Bagshot, Mid-Wales, Millbrook, Severn Valley, Kayel Graphics and the Cambrian Rally as these were all rallies which included stages used on more prestigious events.
