Harold Douglas Baines (born March 15, 1959) is an American former designated hitter and right fielder in Major League Baseball who played for five American League (AL) teams from 1980 to 2001, and is best known for his three stints with the Chicago White Sox. A Maryland native, he also played seven years with his hometown team, the Baltimore Orioles, over three separate periods. The first overall selection in the 1977 Major League Baseball draft and a six-time All-Star, Baines led the AL in slugging percentage in 1984. He held the White Sox team record for career home runs from 1987 until Carlton Fisk passed him in 1990; his total of 221 remains the club record for left-handed hitters, as do his 981 runs batted in (RBI) and 585 extra base hits with the team. His 1,688 hits and 1,643 games as a DH stood as major-league records until David Ortiz broke them in 2013 and 2014. He also held the mark for career home runs as a DH (236) until Edgar Martínez passed him in 2004.
One of the most durable, consistent, and respected hitters of his era, Baines batted over .300 eight times and hit .324 in 31 career postseason games, topping .350 in five separate series. Upon his retirement, he ranked seventh in AL history in games played (2,830) and 10th in RBI (1,628). Noted as well for his power hitting in clutch situations, he was tied for seventh in AL history in grand slams (13), fourth in three-home-run games (three), and tied for seventh in major league history in walk-off home runs (10). He served as a coach with the White Sox from 2004 to 2015 before moving into a role of team ambassador and spring training instructor. Baines was elected to the Baseball Hall of Fame by the Today's Game Era Committee as part of the class of 2019.
Baines was raised in St. Michaels, Maryland, by his father, Linwood, a stonemason, with his three brothers and a sister. He described his father as his "idol, more than anybody else." His father was separated from his mother, Gloria. White Sox owner Bill Veeck began scouting Baines when he was just 12 years old while Veeck was living on the Eastern Shore of Maryland.
He graduated in 1977 from St. Michaels High School on Maryland's Eastern Shore where, as a senior, he batted .532 and was named a high school All-American. The White Sox made Baines the first overall selection in the 1977 amateur draft. He received a signing bonus of $32,000 – a record low for a first overall pick.
On April 10, 1980, Baines made his major league debut on Opening Day, starting in right field and going 0-for-4 in a 5–3 loss to the Baltimore Orioles. In 1982, he batted .271 with 25 home runs and 105 RBI in 161 games. The 1983 season saw Baines reach the postseason with the White Sox, with Baines batting .280. On September 17, Baines drove three runs in for the Sox against the Seattle Mariners, which included a walk-off sacrifice fly that gave them the win and helped clinch the American League West division title, which was their first playoff appearance since the 1959 pennant winning team.
In 1984, baseball writer Bill James called Baines his favorite opposing player to watch, saying, "He is gorgeous, absolutely complete. I've seen him drop down bunts that would melt in your mouth, come up the next time and execute a hit and run that comes straight off the chalkboard. I've seen him hit fastballs out of the yard on a line, and I've seen him get under a high curve and loft it just over the fence." Baines ended the longest game in major league history (eight hours and six minutes over 25 innings on successive evenings) with a walk-off home run against the Milwaukee Brewers' Chuck Porter on May 8, 1984; the bat he used is currently kept at the Baseball Hall of Fame.
In 1986, a succession of knee problems began which gradually ended his fielding career, forcing him to become a regular designated hitter. He suffered a right knee injury in September when he tried to reach first base and saw his foot step on the pitcher's ankle that was on the bag. He finished with his fifth consecutive 20-HR season to become the first White Sox in franchise history to do so in franchise history. He spent half of 1987 spring training rehabbing from an arthoscopic procedure that became the first of eight knee surgeries. Despite the knee ailments and the resulting lack of speed, he remained a powerful hitter, picking up 166 hits in 1988.
Baines holds the record for the most seasons by a player between 100-RBI seasons, with 14 seasons between 113 RBIs for Chicago in 1985 and 103 for Baltimore and Cleveland in 1999.
Midway through the 1989 season, the Texas Rangers acquired Baines, along with Fred Manrique, from the White Sox in a much-derided trade which sent Wilson Álvarez, Scott Fletcher and Sammy Sosa to Chicago. After the trade, the White Sox retired Baines's #3 on August 20, 1989, a rare occurrence for a player who was still active in the major leagues (the number would be "un-retired" each time Baines returned to the White Sox, and he wore it as a coach). Baines finished the decade with 1,547 hits, which ranked sixth to all players in the 1980s.
On August 29, 1990, Baines was traded to the Oakland Athletics for minor league pitchers Scott Chiamparino and Joe Bitker, and he helped them reach the postseason only to be swept by the Cincinnati Reds in the World Series. In 1992, the Athletics returned to the playoffs, but lost to the Toronto Blue Jays in the ALCS.
On January 14, 1993, Baines was traded by the Athletics to the Baltimore Orioles for minor league pitchers Bobby Chouinard and Allen Plaster. Baines batted .313, .294 and .299 over his first three seasons with Baltimore. On December 11, 1995, Baines returned to the White Sox as a free agent. On July 29, 1997, Baines was traded back to the Orioles for a player to be named later. He helped the Orioles reach the playoffs, where they lost to the Cleveland Indians in the League Championship Series.
Baines represented the Orioles in the 1999 All Star Game. On August 27, 1999, he was traded to the Cleveland Indians for minor league pitcher Juan Aracena and a player to be named later. On December 9, 1999, Baines returned for a third stint with the Orioles, signing a one-year, $2 million contract. He was traded back to the White Sox with catcher Charles Johnson in exchange for Miguel Felix, Juan Figueroa, Brook Fordyce and Jason Lakman on July 29, 2000.
He played a total of 32 games in the 2001 season. In June, he was put on the disabled list for a strained left hip flexor after trying to elude an inside pitch that saw speculation that he was close to retiring. He returned for one final game on September 27, where he appeared as a pinch-hitter in the seventh innign and struck out in his one at-bat that proved to be his final game. He finished his career with 2,866 hits, 384 home runs and 1,628 RBI. He was in the top 40 for hits, home runs, and RBIs when he retired, with his RBIs being 21st in MLB history (he now ranks 34th as of 2026). One of 44 players with eleven 20-HR seasons at the time, he also led all players in home runs for players who played at least 50 percent of their games as a designated hitter; his 979 RBIs at the position were topped by Edgar Martinez in 2004. A dedicated hitter, his batting average was higher with runners on base (.306) than with the bases empty (.275). He batted .324 in the postseason with five home runs and 16 RBIs.
Baines's fourth stint with the Chicago White Sox began when he was named bench coach in March 2004 under new manager Ozzie Guillén, his White Sox teammate, from 1985 to 1989 and in 1996–97. Baines served as the team's interim manager for four games, from August 17–20, 2004, while Guillén was serving two consecutive two-game suspensions.
In 2005, as a coach for the White Sox, he earned a World Series ring when the White Sox won the World Series.
On July 20, 2008, the White Sox unveiled a bronze statue of Baines at U.S. Cellular Field prior to their game against the Kansas City Royals; it is the seventh statue featured on the park's outfield concourse.
