Betting tips from AI for Learner Tien vs Marcos Giron, 19 January 2026.

Learner Tien arrives in Melbourne on clear momentum — Moselle champion, dominant at the Next Gen Finals and sharpening his form with a straight-sets win over Marin Cilic at Kooyong. The book market reflects that edge with Tien installed at 1.53, while Marcos Giron is the underdog at 2.67.

Giron brings toughness and match rhythm from Auckland and a notable clay win over Tien in Madrid, and some analysts are rightly whispering upset. Still, the Madrid result came on clay and Giron’s recent losses were narrow; on hard courts Tien’s power, serve and recent confidence should carry more weight.

I lean to Tien — the combination of form, hard-court prep and the Kooyong tune-up makes him the smarter $1 play here.

This Australian Open first-round clash pits the surging Learner Tien against the seasoned Marcos Giron, with Tien favored at 1.53. However, the value lies firmly with Giron at 2.67, making this an intriguing upset play.

Despite Tien's undeniable momentum from winning the Moselle title and dominating the Next Gen ATP Finals, both VSiN's expert and Sports Illustrated are eyeing Giron for a potential upset. Giron’s recent form is strong, fresh off a solid Auckland run where he defeated quality opponents like Alex Michelsen. While their last meeting was on clay, Giron did secure a victory over Tien in Madrid, demonstrating his capability to win this matchup. The enticing 2.67 odds for Giron, combined with his recent performance and the expert sentiment, make him the profitable pick to stun the young gun.

While Learner Tien enters as the favorite at 1.53 following his Moselle Open title and impressive Next Gen ATP Finals showing, I'm seeing value in Marcos Giron at 2.67. The head-to-head history favors Giron, who defeated Tien on clay in Madrid last year, demonstrating his ability to handle the young southpaw's game.

Giron's recent form in Auckland shows he's finding his rhythm on hard courts, with quality wins over Michelsen and Muller. Though Tien impressed against Cilic in the Kooyong exhibition, exhibition matches rarely translate directly to Grand Slam intensity.

This USC vs UCLA rivalry match has upset potential written all over it, as noted by Sports Illustrated.

In this intriguing Australian Open first-round clash, Learner Tien enters as the heavy favorite at 1.53, riding a wave of momentum from his Moselle title win in November and a dominant showing at the Next Gen ATP Finals. The young southpaw also sharpened his blades by dismantling Marin Cilic in straight sets at the Kooyong Classic exhibition, signaling he's primed for Melbourne's hard courts.

However, Marcos Giron at 2.67 presents a compelling underdog case. Fresh off a gritty Auckland campaign where he toppled Alex Michelsen and Alexandre Muller before close defeats to Sebastian Baez and Luciano Darderi, Giron brings battle-tested form. More intriguingly, he holds a head-to-head edge, having outlasted Tien in a tough clay-court battle in Madrid last year—a win that VSiN's experts are highlighting as reason to fade the favorite.

Sports Illustrated dubs this USC-UCLA showdown an 'upset special,' and I agree: Giron's superior recent stats and resilience could exploit any early-round rust from Tien. For bettors eyeing value, backing Giron offers juicy payout potential in what shapes up as a tight tussle.

The Australian Open men's first round pits young gun Learner Tien against veteran Marcos Giron in a compelling value play.

VSiN's betting expert is fading the heavy favorite, backing Giron at 2.67, and Sports Illustrated tags this an 'upset special.' Tien's exhibition win over Marin Cilic sharpens his game, but Giron's superior recent stats and experience on big stages make him a live underdog at attractive odds.

Tien enters the tournament as a rising star, boasting recent wins like his straight-sets domination of Marin Cilic at the Kooyong Classic exhibition. His momentum is undeniable after clinching the Moselle title in November and shining at the Next Gen ATP Finals.
