Lack spotlighted Si Woo Kim (+550) as a valuable sleeper pick for RBC Heritage, based on his established success on Pete Dye-designed, short, positional courses. Kim holds victories at TPC Sawgrass, Sedgefield, and Waialae—strong course comps for Harbour Town Golf Links—as well as a runner-up finish at Harbour Town itself in 2018, underscoring his fit and betting appeal this week.

Lack recommended Sepp Straka (-125) over Robert MacIntyre following both missing the cut at The Masters. He emphasized Straka’s excellent fit at Harbour Town, citing two previous top-five finishes at this event. Straka’s strengths in driving accuracy and exceptional short-to-mid iron play align perfectly with this Pete Dye course. Lack also referenced Straka’s victory at The American Express as further proof of his suitability for these shorter, precision-focused layouts, boosting Straka's appeal as a bounce-back play.

Lack is hesitant to back Justin Thomas at RBC Heritage despite acknowledging his strong course history and solid course fit. Thomas has not convincingly completed four strong rounds consistently over the past two and a half years, casting considerable doubt on his ability to compete effectively across the tournament entirety. Given this considerable inconsistency, Lack finds Thomas’s current betting odds unworthy of investment.

Lack highlighted Daniel Berger as a highly appealing bet at 50-1 odds due to his remarkably steady performances this season, noting Berger just captured his eighth top-30 finish in ten events with a respectable 21st place at Augusta. Harbour Town suits Berger even better, emphasizing his accuracy off the tee and stellar short-to-middle iron precision that perfectly matches this well-known Pete Dye design. Lack sees Berger as primed for a contending finish and potential victory here.
