Esteban Loaiza pitched 14 seasons in the major leagues. Most years Loaiza would end up with a modest ERA and he bounced from team to team, always useful but never dominant. The exception was in 2003, when, pitching for the Chicago White Sox his 2.90 ERA was third in the American League, he won over 20 games, led the league in strikeouts, started the 2003 All-Star Game and was second in the Cy Young Award voting. Outside of this career year, his highest seasonal win total was 12, with the Washington Nationals in 2005. This low win total was despite the fact he remained a regular member of starting rotations for most of his career, six times starting 30+ games in a season. Loaiza pitched for numerous decent teams, reaching the postseason on three different occasions.
In 2006, he had a record of 11-9, but his ERA of 4.89 was the lowest of the Oakland Athletics' four regular starters. On June 14, 2006, he was arrested for driving his Ferrari over 120 mph and driving drunk.
