Seaver was born in Fresno, California, to Betty Lee (Cline) and Charles Henry Seaver. Pitching for Fresno High School, Seaver compensated for his lack of size and strength by developing great control on the mound. Despite being an All-City basketball player, he hoped to play baseball in college. He joined the United States Marine Corps Reserves on June 28, 1962.
Seaver and the Mets were stunned on January 20, 1984 when he was claimed in a free-agent compensation draft by the Chicago White Sox. The team (especially GM Frank Cashen) had incorrectly assumed that no one would pursue a high-salaried, 39-year-old starting pitcher, and left him off the protected list. Faced with either reporting to the White Sox or retiring, Seaver chose the former. The result for the Mets was an opening in the starting rotation that allowed Dwight Gooden to be part of the team. Seaver pitched two and a half seasons in Chicago and recorded his last shutout on July 19, 1985 against the visiting Indians. In an anomaly, Seaver won two games on May 9, 1984; he pitched the 25th and final inning of a game suspended the day before, picking up the win in relief against the Milwaukee Brewers, before starting and winning the day's regularly scheduled game, also facing the Brewers. After Seaver's 298th win, a reporter had pointed out to White Sox catcher Carlton Fisk that following his upcoming start in Boston, Seaver's next scheduled start would be in New York, and that the possibility existed that he might achieve the mark there. Fisk emphatically stated that Seaver would win in Boston, and then would win his 300th. On August 4, 1985, Seaver recorded his 300th victory at Yankee Stadium against the Yankees, throwing a complete game 4-1 victory. Don Baylor was the tying run at the plate; he hit a fly ball to left field for the final out of the game. Coincidentally, it was Phil Rizzuto Day - Seaver would later become Rizzuto's broadcast partner for Yankee games. Lindsey Nelson, a Mets radio and TV announcer during Seaver's Mets days, called the final out for Yankees TV flagship WPIX.

Did Seaver play for any other baseball teams when attempting his 300 wins

George Wright (January 28, 1847 - August 21, 1937) was an American baseball player. He played shortstop for the original Cincinnati Red Stockings, the first fully professional team, when he was the game's best player. In 1868, Wright won the Clipper Medal for being the best shortstop in baseball. He was elected to the Baseball Hall of Fame in 1937.
Harry Wright was hired to organize a new team in Boston, where he signed three teammates including George for 1871. He brought along the nickname, too; if the nickname is the tenth man or the player-manager counts double, Harry thereby composed half the team that just missed winning the first National Association pennant. George suffered a broken leg and missed half the season; one more win at the right time would have been decisive in Boston's favor. With some personnel changes, the Boston Red Stockings won the other four NA pennants, dominating so severely in 1875 that they helped provoke a new league. The team trailed badly in the first National League season, after the defection of its Big Four western players to Chicago, but rebounded to win again both 1877-78. George Wright had played an even decade for Harry's teams, beginning with the First Nine and closing with six league championships in seven. (Another 1869 hire, Andy Leonard, was present for all but the 1871 second-place finish.) The Providence Grays, new in the NL for 1878, hired George to lead the team in 1879. He did as well as possible, wrestling the championship for himself from older brother Harry; for Providence and Rhode Island from older and regionally dominant Boston and Massachusetts. But Wright & Ditson Sporting Goods was growing, so George returned to Boston for business reasons. He remains the only man to win the pennant in his lone season as manager. Meanwhile, the National League introduced the reserve list system, and Providence listed George, so he was not free to sign with Boston. (Until the 1879-80 off-season, every professional baseball player was a "free agent" for every season.) During the next two seasons he played only a few games.. When Boston changed managers for 1882, Harry signed to lead Providence and inherited the right to sign his brother. George agreed to play another season full-time, retiring after the 1882 season with a .302 batting average in the major leagues from 1871. In 1882 George Wright took up cricket seriously again with the Longwood Cricket Club of Boston where he dominated local cricket sides with Isaac Chambers, the Longwood cricket pro and greenskeeper, holding up the other bowling end. In 1891 George Wright captained the Longwood Cricket Club against Lord Hawke's visiting English side. Wright's side surprised the visiting English first-class players with accurate bowling which kept the tourist in check. In 1892 George Wright donated cricket gear to British Guianese (Guyana) cricket players thereby starting a century old tradition of West Indian cricket in New England.

When did he play his last game?

George agreed to play another season full-time, retiring after the 1882

Mario Lanza (born Alfredo Arnold Cocozza; January 31, 1921 - October 7, 1959) was an American tenor of Italian ancestry, and an actor and Hollywood film star of the late 1940s and the 1950s. Lanza began studying to be a professional singer at the age of 16. After appearing at the Hollywood Bowl in 1947, Lanza signed a seven-year film contract with Louis B. Mayer, the head of Metro-Goldwyn-Mayer, who saw his performance and was impressed by his singing.
Lanza was the first RCA Victor Red Seal artist to win a gold disc and the first artist to sell 2 1/2 million albums Lanza was referred to by some sources as the "new Caruso" after his "instant success" in Hollywood films, while MGM hoped he would become the movie studio's "singing Clark Gable" for his good looks and powerful voice. In 1994, outstanding tenor Jose Carreras paid tribute to Lanza during a worldwide concert tour, saying of him, "If I'm an opera singer, it's thanks to Mario Lanza." His equally outstanding colleague Placido Domingo echoed these comments in a 2009 CBS interview with, "Lanza's passion and the way his voice sounds are what made me sing opera. I actually owe my love for opera ... to a kid from Philadelphia." Even today "the magnitude of his contribution to popular music is still hotly debated," and because he appeared on the operatic stage only twice, many critics feel that he needed to have had more "operatic quality time" in major theaters before he could be considered a star of that art form. His films, especially The Great Caruso, influenced numerous future opera stars, including Joseph Calleja, Jose Carreras, Placido Domingo and Luciano Pavarotti. According to opera historian Clyde McCants, "Of all the Hollywood singers who performed operatic music ... the one who made the greatest impact was Mario Lanza." Hollywood gossip columnist Hedda Hopper concluded that "there had never been anyone like Mario, and I doubt whether we shall ever see his like again".
