he was hit with a beer thrown by an unruly fan on his way back to the dugout. Giambi continued slugging with New York in 2002. He led the league for the second consecutive year in times on base (300), had 109 walks (second), was third in the league with both a .435 OBP and 15 HBP, had 41 home runs (fourth), 120 runs (fourth; a career high), and a .598 slugging percentage (fourth), knocked in 122 runs (fifth), and batted .314 (sixth). He came in fifth in AL MVP voting, and again won the Silver Slugger Award. He also hit an "ultimate grand slam"—a walk-off grand slam against the Twins in a rain-soaked extra-inning game, that won that game 13–12. Although his average dipped to .250 in 2003, he led the league in walks (129) for the third time in his career and in HBP (21) and percent of plate appearances that were walks (19.4%), maintained an extremely high on-base percentage (.412; third in the league), hit 41 home runs (fourth), and had 107 RBIs (eighth). He was also second in the major leagues in fly ball percentage (52.0%). He remained one of the most patient hitters in the majors. At the same time, he also led the league in strikeouts (140), the only season that he has even been in the top 10 in the league in that category. On July 30, 2004, test results confirmed that Giambi had a benign tumor, which placed him on the disabled list. He was treated for the tumor, and returned to the team for their game against the Kansas City Royals on September 14. That year, Giambi was voted in as the starting first baseman in the 2004 MLB All-Star Game despite finishing the year with a .208 batting average and just 12 home runs. Giambi's performance in 2004 was so poor that he was not added to the Yankees postseason roster. Towards the middle of the 2005 season, Giambi saw a resurgence in his career. On July 31, he hit his 300th career home run off of Esteban Yan of the Los Angeles Angels of Anaheim. This was his 14th home run of the month, tying Mickey Mantle for the Yankee record for home runs in July. Giambi ended the 2005 season leading the major leagues in walk percentage (20.6%) and leading the American League in walks for the fourth
