From 1991 to 1997, Thomas finished in the top 10 of the MVP voting every year. In , Thomas won the batting title and finished third in MVP voting. However, due in part to personal strife off the field, his offensive production wavered during the next two seasons. Never a defensive standout at first base during the early part of his career, Thomas nonetheless preferred playing in the field to serving as a designated hitter, saying that it kept him focused; the fact that he did generally hit better as a first baseman created a dilemma over the years for the White Sox as to whether to use him as a DH, which would reduce wear on his body but might cost some offensive production. By the late 1990s, minor injuries were tending to keep him unavailable for short periods, and 1997 was the last year in which he played more in the field than as a DH. Thomas rebounded with force in when he hit .328 with a career-high 43 homers and 143 runs batted in. Thomas finished second in MVP voting that season, behind Jason Giambi of the Oakland Athletics. Thomas also won the 2000 AL Comeback Player of the Year Award. But this would not mean an end to the rocky path he would follow later in his career.
