Question: What profession do Hughie Jennings and Joe Kelley have in common?

Context paragraphs:
Nurse stereotypes: A stereotype is a generalized idea or image about a particular person or thing that is often oversimplified and offensive.  Stereotypes are victim of prejudice when negative portrayals of a group are untrue of individual members.  Nursing has been stereotyped throughout the history of the profession.  A common misconception is that all nurses are female; this has led to the stereotype of male nurses as effeminate.  These generalized ideas of the nursing profession have formed a skewed image of nurses in the media.  The image of a nurse projected by the media is typically of a young white single female being over-sexualized as well as diminished intellectually; this idea is then portrayed in get-well cards, television shows and novels.  The over-sexualized nurse is commonly referred to as a naughty nurse and is shown as a sex symbol or nymphomaniac. Along with these common stereotypes, studies have identified several other popular images used in media such as handmaiden, angel, torturer, homosexual male, alcoholic, buffoon and woman in white.  Common stereotypes of nursing and portrayal of these misconceptions have fueled a discussion on the effects they have on the profession, harmful or good.

Mert Hackett: Mortimer Martin "Mert" Hackett (November 11, 1859 – February 22, 1938), was an American Major League Baseball player from Cambridge, Massachusetts, who played mainly as a catcher from 1883 to 1887 for three different team; the Boston Beaneaters, Kansas City Cowboys, and Indianapolis Hoosiers.  His brother, Walter Hackett, and cousins John Clarkson, Walter Clarkson, and Dad Clarkson as well as Tim Keefe and Joe Kelley (all born in Cambridge, Massachusetts) also played in the majors.

Convention (meeting): A convention, in the sense of a meeting, is a gathering of individuals who meet at an arranged place and time in order to discuss or engage in some common interest.  The most common conventions are based upon industry, profession, and fandom.  Trade conventions typically focus on a particular industry or industry segment, and feature keynote speakers, vendor displays, and other information and activities of interest to the event organizers and attendees.  Professional conventions focus on issues of concern to the profession and advancements in the profession.  Such conventions are generally organized by societies or communities dedicated to promotion of the topic of interest.  Fan conventions usually feature displays, shows, and sales based on pop culture and guest celebrities.  Science fiction conventions traditionally partake of the nature of both professional conventions and fan conventions, with the balance varying from one to another.  Conventions also exist for various hobbies, such as gaming or model railroads.

Joe Kelley: Joseph James Kelley (December 9, 1871 – August 14, 1943) was an American left fielder in Major League Baseball (MLB) who starred in the outfield of the Baltimore Orioles teams of the 1890s.  Making up the nucleus of the Orioles along with John McGraw, Willie Keeler, and Hughie Jennings, Kelley received the nickname "Kingpin of the Orioles".

Send 'er down, Hughie!: Send 'er down, Hughie! , sometimes Send her down, Hughie!  or Send it down, Hughie! , is an idiomatic Australian phrase uttered in response to the onset of rain.  It was in very common usage in the early 20th century, but is less common now.

Hughie Jennings: Hugh Ambrose Jennings (April 2, 1869 – February 1, 1928) was an American professional baseball player, coach and manager from 1891 to 1925.  Jennings was a leader, both as a batter and as a shortstop, with the Baltimore Orioles teams that won National League championships in 1894 , 1895 , and 1896 .  During those three seasons, Jennings had 355 runs batted in and hit .335, .386, and .401.  Jennings was a fiery, hard-nosed player who was not afraid to be hit by a pitch to get on base.  In 1896, he was hit by pitches 51 times – a major league record that has never been broken.  Jennings also holds the career record for being hit by pitches with 287, with Craig Biggio (who retired in 2007) holding the modern-day career record of 285.  Jennings also played on the Brooklyn Superbas teams that won National League pennants in 1899 and 1900.  From 1907 to 1920, Jennings was the manager of the Detroit Tigers, where he was known for his colorful antics, hoots, whistles, and his famous shouts of "Ee-Yah" from the third base coaching box.  Jennings suffered a nervous breakdown in 1925 that forced him to leave Major League Baseball.  He died in 1928 and was posthumously inducted into the Baseball Hall of Fame in 1945.

Closing In on the Fire: Closing In on the Fire is an album by Waylon Jennings, released on the small Ark 21 Records label on June 16, 1998.  It features contributions from several celebrities associated with both country and rock music.  The selections include, among others, Sting's "She's Too Good for Me" and Tony Joe White's title track, creating a greater degree of musical eclecticism than in many previous Jennings releases.  The singer incorporated elements of genres such as blues and rock, in addition to traditional country ballads.  "Best Friends of Mine", an autobiographical song, is a tribute to Buddy Holly, Hank Williams, Jr. and one of Jennings' close friends from his days in Phoenix.  Carl Smith, one of the performer's idols, appears on "Untitled Waltz".  In an interview, the singer mentioned that he wasn't fully satisfied with his take on The Rolling Stones' "No Expectations", calling it ""a little more contrived than I would have liked"".  An interview featuring Jennings commenting on the record is included as a bonus track.  "Closing In on the Fire", Jennings' 72nd release, reached #71 on the country charts and was the last studio album by the singer to be released before his death in 2002.

Bill Pounds: Jeared Wells "Bill" Pounds (March 11, 1878 – July 7, 1936) was a pitcher in Major League Baseball.  He appeared in just two major league games, one each for Cleveland and Brooklyn in 1903, but the only surviving images of him in a major league uniform show him with the New York Highlanders.  Bill Pounds was born in Paterson, New Jersey, and had a long career as a minor league pitcher.  His professional career began in 1899 when he pitched for both Binghamton and Paterson.  After a year out of organized baseball, he played in 1901 and 1902 for two Ilion and Utica in the New York State League.  After reportedly signing a contract to return to Utica for 1903, he was signed by Cleveland in the American League and was on their Opening Day roster.  Pounds was brought in to pitch on May 2 in the fourth inning in Chicago when the White Stockings had opened up a big lead; he gave up seven runs (six earned) on eight hits in the 16-6 loss.  On May 18 he was released by Cleveland and was signed shortly thereafter by the New York Highlanders.  Pounds was in uniform with the team when the Highlanders visited Chicago for a series May 20–22.  A photographer from the Chicago Daily News was taking pictures of the players on the teams visiting both the American League and National League ballparks, and during this visit Pounds had his image preserved for posterity.  Before the end of the month, without having appeared in a game for New York, Pounds was sent back to Cleveland, apparently because he could not come to terms on a contract.  On June 4 he was signed by Brooklyn of the National League, but he did not appear in a game until June 30.  With Pittsburg ahead 12-0 after three innings, Pounds was sent in to pitch.  He allowed five runs (four earned) in six innings on eight hits and two walks in the 17-8 loss, and gave up a long home run to Honus Wagner.  On July 3, his contract was transferred to Baltimore of the Eastern League, along with that of Hughie Jennings and three other Dodgers.  Pounds would never appear in another major league game; though his pitching record was unimpressive, he finished with a lifetime batting record of three hits in five at-bats.  Late in the 1903 season, his contract was purchased by Denver, but it is unclear whether he actually played in Colorado.  For the remainder of his minor-league career, from 1904 through 1911, he pitched for teams within a couple of hundred miles of his birth—four teams in the New York State League and two in the Tri-State League.  In the off-seasons he would sometimes pitch for the Paterson Elks team, and he continued to pitch for them after his minor-league career had ended.  According to The Sporting Life, “Pounds has speed and a rather good assortment of curves.  He has not the best control in the world.”  A few years after his career had ended, the Utica Observer described him in this way: “Bill Pounds was the champion sweater of the league.  He perspired so much that…a miniature lake (formed) around the slab.”  He died in 1936 in the city of his birth, aged 58.  Early in the 21st century, the photographic archives of the Chicago Daily News were posted online.  Although his teammates’ photographs were easily identified, the image of Pounds remained unidentified, or occasionally misidentified as Doc Adkins, for at least a decade.
