Majchrzak, ranked No. 133 but rusty after a year-long doping suspension, has struggled lately with early qualifying exits at Indian Wells and modest challenger results. No head-to-head exists, but Tien's momentum, home-crowd boost, and junior Grand Slam pedigree outweigh Majchrzak's experience amid uncertain post-ban form, though upsets remain possible in early Masters 1000 rounds.",
