Australian Open glance: 20-somethings Thiem, Zverev in SF

MELBOURNE, Australa (AP) — A quick look at the Australian Open:

LOOKAHEAD TO FRIDAY

Alexander Zverev is 22, Dominic Thiem is 26, and one of them will get the chance to appear in the Australian Open final for the first time. Their semifinal is under the lights at night in the only singles match of Day 12 at Melbourne Park. It’s a matchup between two of the 20-somethings that folks have been expecting to break through the Grand Slam dominance of the Big Three: Rafael Nadal, Novak Djokovic and Roger Federer combined to win the past 12 major championships in a row. While this is the first time in a major semifinal for the No. 7-seeded Zverev, it is the fifth for No. 5 Thiem, whose previous four all came at the French Open, where he lost in the past two finals to Nadal. Thiem eliminated 19-time major champion Nadal in a thriller in the quarterfinals Wednesday; Zverev got past three-time major champion Stan Wawrinka.
