In September, Holliday led the NL with 32 RBI, setting a Rockies record for that month. On September 20 against the Padres, he hit two home runs and tied a Rockies' single-game record with eight RBI in a Rockies 20–1 victory, the highest single-game RBI total in the NL in 2005 and second-highest in the major leagues. He ended the season with a seven-game hitting streak and reached base in each of the Rockies' final 22 games. Holliday totaled 125 games and improved in nearly all offensive categories from his rookie year, including 147 hits, 19 home runs, 87 RBI, 68 runs, 14 stolen bases, 242 total bases, 505 slugging percentage and .361 on-base percentage. His .307 batting average placed eighth in the NL. The club picked up his option for 2006, which was worth $500,000 ($ today), or about $100,000 ($ today) more than the average for a player with equivalent service time. He was selected as the Rockies Player of the Year.
