In Episode 3 of Whiskey High IQ's "Why I Suck at Short Putts?" training mode, the focus is on improving putting performance by assessing and training three key components: Read, Speed, and Start Line. Brian Bailie emphasizes that reading the green is the most crucial for short putts, recommending using your feet to gauge slope severity. Speed control, or distance control, is developed through structured practice, adjusting stroke length and timing to roll putts consistently past the hole without over-hitting. Lastly, start line accuracy is addressed by ensuring the putter face remains within a degree of the target line. By mastering these skills, golfers can significantly improve their short putting percentages, building a reliable foundation for long-term performance improvement.
