‘It’s tricky’: How caddie Michael Greller tells Jordan Spieth ‘no’

The Unique Dynamic of Jordan Spieth and Michael Greller
Jordan Spieth and his caddie, Michael Greller, share one of the most intriguing player-caddie relationships on the PGA Tour. Known for Spieth’s confidence and daring shot-making, their partnership often requires careful communication and strategic compromise.

During a recent Sentry Tournament, a rare moment unfolded when Spieth, initially adamant about using his driver, switched to Greller’s recommendation of a 3-wood. The change proved successful, leading to a birdie. This instance highlighted not only Greller’s keen judgment but also a subtle shift in Spieth’s openness to his caddie’s advice.

As Greller explained in a discussion with *No Laying Up*, caddies must balance supporting their player’s confidence while tempering risky decisions—a challenge made trickier by Spieth’s belief in his ability to pull off improbable shots.

Evolving Systems of Communication
Over the years, Spieth and Greller have experimented with different systems to manage on-course disagreements, reflecting their evolving dynamic. From “vetoes” to a stoplight system, their methods have ranged from structured to situational. Ultimately, they landed on a numbers-based approach, which incorporates data such as yardage and conditions to guide decisions.

This framework allows both to align on strategy without undermining Spieth’s confidence or creativity. The mutual respect in their partnership was evident during a lighthearted exchange about Greller’s persuasive abilities, with Spieth jokingly likening him to a skilled lobbyist.

Their collaboration is a testament to the trust and adaptability required for success at golf’s highest level, showcasing how even bold players like Spieth can thrive when guided by steady, thoughtful support.
