Nonetheless, Henderson and the Mets were an uneasy fit. Following the Mets' loss in the 1999 NLCS, the New York press made much of a card game between Henderson and Bobby Bonilla. Both players had been substituted out of the lineup, and they reportedly left the dugout before the playoff game had concluded. In May 2000, Henderson was released by the Mets, and quickly signed as a free agent with the Seattle Mariners. In only his second game as a Mariner, on May 20, Henderson hit a leadoff home run, thus becoming the third player to hit a home run in four different decades (Ted Williams and Willie McCovey were the others, and Omar Vizquel became the fourth in 2010). Despite the late start, Henderson finished fourth in the AL in stolen bases (31). A free agent in March 2001, Henderson returned to the Padres. During the 2001 season, he broke three major league career records and reached an additional major career milestone. He broke Babe Ruth's record of 2,062 career walks, Ty Cobb's record of 2,245 career runs, and Zack Wheat's record of 2,328 career games in left field, and on the final day of the season collected his 3,000th career hit, a leadoff double off Rockies pitcher John Thomson. That final game was also Tony Gwynn's last major league game, and Henderson had originally wanted to sit out so as not to detract from the occasion, but Gwynn insisted that Henderson play. After scoring the game's first run, Henderson was removed from the lineup. With Gwynn having 3,141 hits, it was just the second time in Major League history that a pair of teammates each had 3,000 career hits; Ty Cobb and Tris Speaker had previously played many games together for the 1928 A's. At the age of 42, in his last substantial major league season, Henderson finished the year with 25 stolen bases, ninth in the NL; it also marked his 23rd consecutive season with more than 20 steals. Of the ten top base stealers who were still active as of 2002, the other nine each stole fewer bases in 2002 than the 42-year-old Henderson. In February 2002, Henderson signed as a free agent with the Boston Red Sox, where at age 43 he became the oldest player to play center field in major league history when he replaced Johnny Damon for three games in April and another in July. Henderson's arrival was marked by a statistical oddity. During the 22.5 years from his June 1979 debut through the end of the 2001 season, he had stolen more bases by himself than his new team had: 1,395 steals for Henderson, 1,382 for the Boston franchise.
