My guess Crawford had 123 so close
Lofton started in the Majors in 1991

Yeah, but the question was "of the players who appeared in the 21st century" and Lofton retired after the 2007 season.  He retired with 116 triples, so also close, but Bob closer.  When Lofton retired, it was the first time since 1885 that there were no active players with 100 triples, which lasted until 2010, when Crawford hit his 100th triple.  Two years later, Reyes hit his 100th triple.  Since he retired after the 2018 season, MLB has had no active player with 100 career triples.  Dexter Fouler is the active career leader with 82, so it may be a while before the next 100 triple player, if ever.
