Some context: King was born in Long Beach, California, into a conservative Methodist family, the daughter of Betty (nee Jerman), a housewife, and Bill Moffitt, a firefighter. Billie Jean's family was athletic. Her mother excelled at swimming, her father played basketball, baseball and ran track. Her younger brother, Randy Moffitt, became a Major League Baseball pitcher, pitching for 12 years in the major leagues for the San Francisco Giants, Houston Astros, and Toronto Blue Jays.
King's triumph at the French Open in 1972 made her only the fifth woman in tennis history to win the singles titles at all four Grand Slam events, a "career Grand Slam." King also won a career Grand Slam in mixed doubles. In women's doubles, only the Australian Open eluded her.  King won a record 20 career titles at Wimbledon - six in singles, 10 in women's doubles, and four in mixed doubles.  King played 51 Grand Slam singles events from 1959 through 1983, reaching at least the semifinals in 27 and at least the quarterfinals in 40 of her attempts. King was the runner-up in six Grand Slam singles events. An indicator of King's mental toughness in Grand Slam singles tournaments was her 11-2 career record in deuce third sets, i.e., third sets that were tied 5-5 before being resolved.  King won 129 singles titles, 78 of which were WTA titles, and her career prize money totaled US$1,966,487.  In Federation Cup finals, King was on the winning United States team seven times, in 1963, 1966, 1967, and 1976 through 1979. Her career win-loss record was 52-4. She won the last 30 matches she played, including 15 straight wins in both singles and doubles. In Wightman Cup competition, King's career win-loss record was 22-4, winning her last nine matches. The United States won the cup ten of the 11 years that King participated. In singles, King was 6-1 against Ann Haydon-Jones, 4-0 against Virginia Wade, and 1-1 against Christine Truman Janes.

Some context: Clemens was born in Dayton, Ohio, the fifth child of Bill and Bess (Lee) Clemens. He is of German descent, his great-grandfather Joseph Clemens having immigrated in the 1880s. Clemens's parents separated when he was an infant. His mother soon married Woody Booher, whom Clemens considers his father.
Clemens unexpectedly appeared in the owner's box at Yankee Stadium on May 6, 2007, during the seventh-inning stretch of a game against the Seattle Mariners, and made a brief statement: "Thank y'all. Well they came and got me out of Texas, and uhh, I can tell you it's a privilege to be back. I'll be talkin' to y'all soon." It was simultaneously announced that Clemens had rejoined the Yankees roster, agreeing to a pro-rated one-year deal worth $28,000,022, or about $4.7 million per month. Over the contract life, he would make $18.7 million. This equated to just over $1 million per start that season.  Clemens made his 2007 return on June 9, defeating the Pittsburgh Pirates by pitching six innings with seven strikeouts and 3 runs allowed. On June 21, with a single in the 5th inning against the Colorado Rockies, Clemens became the oldest New York Yankee to record a hit (44 years, 321 days). On June 24, Clemens pitched an inning in relief against the San Francisco Giants. It had been 22 years and 341 days since his previous regular-season relief appearance, the longest such gap in major league history.  On July 2, Clemens collected his 350th win against the Minnesota Twins at Yankee Stadium, giving up just two hits and one run over eight innings. Clemens is one of only three pitchers to pitch his entire career in the live-ball era and reach 350 wins. The other two are Warren Spahn (whose catcher for his 350th win was Joe Torre, Clemens's manager for his 350th), and Greg Maddux, who earned his 350th win in 2008. His final regular season appearance was a start against the Red Sox at Fenway Park, in which he allowed 2 hits and 1 unearned run in 6 innings, and received a no-decision. Clemens finished the 2007 regular season with a record of 6-6 and a 4.18 ERA.  Clemens was forced to leave Game 3 of the 2007 ALDS in the third inning after aggravating a hamstring injury. He struck out Victor Martinez of the Cleveland Indians with his final pitch, and was replaced by right-hander Phil Hughes. Yankees manager Joe Torre removed Clemens from the roster due to his injury, and replaced him with left-hander Ron Villone.
Why was he forced to leave
A: a hamstring injury.
Some context: Thomas Lawton was born on 6 October 1919 to Elizabeth Riley and Thomas Lawton senior in Farnworth, Lancashire. His father was a railway signalman of Irish extraction, and his mother worked as a weaver at Harrowby Mill. His father left the family 18 months after Lawton was born, and Elizabeth moved back into her parents' home in Bolton. Elizabeth's father, James Hugh "Jim" Riley, became Lawton's surrogate father.
Lawton played his first game for Burnley Reserves against Manchester City Reserves in September 1935, and though he struggled in this game he went on to become a regular Reserve team player by the age of 16. After a poor run of form from Cecil Smith, Lawton was selected ahead of Smith for the Second Division game against Doncaster Rovers at Turf Moor on 28 March 1936; aged 16 years and 174 days, this made him the youngest centre-forward ever to play in the Football League. Rovers centre-half Syd Bycroft, also making his league debut, marked Lawton out of the game, which ended in a 1-1 draw. Burnley had played poorly, though Lawton was praised for his "keen and fearless" performance by the Express & News newspaper. He retained his place for the following game, and scored two goals in a 3-1 victory over Swansea Town at Vetch Field. He picked up a groin strain in his third appearance which caused him to miss two fixtures, before he returned to the first team for the final four games of the 1935-36 season; he claimed three more goals to take his season tally to five goals from seven games.  Lawton continued to train his heading skills intensely in the summer of 1936, and also played cricket for Burnley Cricket Club as a batsman in the Lancashire League. He scored a six against both Learie Constantine and Amar Singh. He scored 369 runs in 15 completed innings for an average of 24.06.  He turned professional at Burnley at the age of 17 on wages of PS7 a week. His grandfather attempted to negotiate a PS500 signing-on fee on his behalf but was rebuffed after the club alerted Charles Sutcliffe, Secretary of the Football League, who informed them that any attempt to circumvent the league's maximum wage was illegal. Lawton scored in his first appearance since signing the contract after just 30 seconds, before going on to record a hat-trick in a 3-1 win over Tottenham Hotspur, scoring a goal with either foot and one with his head.
