We have an issue where some requests are blocked due to too many images on a page. I'm working on fixing that issue today. Please let me know on User_talk:Admin if you see any issues. Thank you as always for your support.
The 1980s were a generally low-scoring decade in baseball and filled with the usual range of dynasties, upsets and memorable moments.
In Major League Baseball, it was a time of parity, as almost every team was competitive at some point in the decade. The most famous teams of the decade were generally one-year entities like the 1986 New York Mets. The 1988-1989 Oakland Athletics were perhaps the closest any team came to being a dynasty, but they lost the 1988 World Series to the Los Angeles Dodgers in a stunning upset highlighted by Kirk Gibson's pinch-hit home run off Dennis Eckersley when Gibson could hardly walk.
The 1980s were a decade notable for stolen base records. In 1980, Rickey Henderson set an American League record with 100 stolen bases, and Ron LeFlore and Omar Moreno finished first and second in the National League with 97 and 96 respectively. In 1981, Tim Raines set a rookie record with 71. In 1982, Henderson set a major league record with 130 stolen bases. Juan Samuel broke Raines' record for rookies with 72 in 1984, and then Vince Coleman broke it again in 1985 by swiping 110 bases, the first of three consecutive seasons in which he would steal over 100 bases. Coleman had set the minor league stolen base record a couple of years earlier, with 145 for the Macon Redbirds, one year after Jeff Stone had set a record with 122 steals for the Spartanburg Traders. The 100-steal feat has not been repeated since the last of Coleman's consecutive 100+ seasons, in 1987, although the stolen base remained a popular offensive weapon until the early 1990s.
Other notable feats of the 1980s in the majors included Pete Rose setting the all-time hits record and Orel Hershiser breaking Don Drysdale's record for most consecutive shutout innings. The 1987 season was considered a fluke as "The Year of the Home Run" as homer levels rose drastically for one season before falling again. "The Year of the Balk" followed as enforcement of the balk rule was made more stringent. Nolan Ryan and Steve Carlton fought for the all-time strikeout record with Ryan winning the duel and continuing on into the 1990s while Carlton had retired. The decade was also notable for the introduction of a new statistic, the game-winning run batted in, which was supposed to identify the best clutch hitters in the game. Contrary to the save, introduced in the 1970s and which quickly became a staple of the game, the GWRBI never caught anyone's imagination and was quietly dropped at the end of the decade.
Scandals in the 1980s centered around drugs, with the 1985 drug trials affecting several big-league stars. Darryl Strawberry, Dwight Gooden and Steve Howe were among others battling addictions, with cocaine the drug of choice. Rose become bogged down in a scandal involving his having bet on games in which he managed; he would deny allegations until the early 21st Century before he admitted his trespass. Rose was banned from baseball indefinitely by Commissioner Bart Giamatti in August of 1989.
The 1980s were also a time of labor strife. The 1981 season was amputated by a third because of a strike, and over the rest of the decade, owners complained bitterly about rising player salaries and the supposed ill effects of free agency. This led to self-imposed restrictions on spending, such as cutting major league rosters from 25 to 24 players from 1986 to 1989, and collusion to prevent free agents from signing with other teams following the 1985, 1986 and 1987 seasons. This action was the subject of a grievance by players, and led to the owners being forced to pay significant monetary compensation to a number of players who had been free agents during those years.
The Cuban national team dominated international competition, with young stars like Omar Linares and Orestes Kindelan joining established players such as Lourdes Gourriel Sr. and Luis Casanova. Cuba had not yet been rocked by the defections that would start in the 1990s. Baseball was reintroduced to the Olympics as a demonstration sport in 1984 and future stars like Barry Larkin, Mark McGwire, Atsuya Furuta, Will Clark and Jin-woo Song appeared in the 1984 Olympics and 1988 Olympics.
In Nippon Pro Baseball, the Seibu Lions were easily the team of the decade, led by star performers like Kazuhiro Kiyohara, Koji Akiyama, Kimiyasu Kudoh, Hiromichi Ishige, Osamu Higashio, Hisanobu Watanabe and Tetsuya Shiozaki. Sadaharu Oh broke Hank Aaron's all-time international home run record while Sachio Kinugasa topped Lou Gehrig's Consecutive Games Played mark.
