In 1992, at age of 17, Ortiz signed with the Seattle Mariners. He was sent to Minnesota in 1996, and made his debut in September 1997. After moving up and down from the majors to the minors, Ortiz hit .272 with 20 home runs and 75 RBI in 2002, when the Twins lost the American League pennant to the Anaheim Angels. But Ortiz, whose left knee and right wrist had been surgically repaired, had not played in more than 130 games in a season. Thinking he was injured too often, struggled against left-handed pitching, and didn't work hard enough, and also fearing the money he would be awarded in arbitration, Minnesota let Ortiz go, and the Red Sox signed him for $1.25 million.

Along with Bill Mueller and Kevin Millar, Ortiz was another free agent signee who came up big for the Red Sox in 2003. A DH and fifth in the order at bat, he had a huge second half and finished the season hitting .288 with 31 home runs and 101 RBI in 128 games. Considered by many to be the future of the Red Sox franchise, Ortiz finished fifth in the American League MVP selection.

In 2004 Ortiz surpassed all expectations around him by turning in a solid season. Batting in the fourth spot in the batting order, he led the American League in extra base hits (91) and was second in RBI (139); had 33 go-ahead RBI, 50 RBI with two out, and collected career highs in batting average (.301), home runs (41), RBI (139), runs (94), doubles (47), triples (3), walks (75), total bases (351), on base percentage (.380), slugging average (.603), OPS (.983) and games played (150). He is quickly gaining the reputation of being the best clutch hitter in the game

In addition, Ortiz and Manny Ramirez became the first pair of American League teammates to hit 40 home runs, have 100 RBI, and bat .300 since the Yankees Babe Ruth and Lou Gehrig in 1931, and the first Red Sox duo with 40 homers since Tony Armas and Jim Rice (1984). Also along with Ramirez, Ortiz hit back-to-back home runs six times, tying the major league single season set by Hank Greenberg and Rudy York (Detroit Tigers) and Frank Thomas and Magglio Ord󱥺 (Chicago White Sox). Ortiz also hit 24 road home runs, second only to Ted Williams? 26 in 1957. A first time All-Star, he hit a two-run home run, walked twice and scored two runs in the game.
