The withdrawals for the Palmetto Championship keep pilling up as Sung Kang, and Nate Lashley have both withdrawn and will be replaced by Mark Hensby and Ted Purdy:

Kang and Lashley were listed at 160-1 and 110-1 this week on FanDuel Sportsbook, so this will have minimal impact on the overall betting odds.
At the time of writing, Brooks Koepka and Dustin Johnson are listed as the co-favorites to win outright at 8-1. Tyrrell Hatton (14-1) and Matthew Fitzpatrick (16-1) round out the other golfers below 20-1.
Koepka and Hatton are both in solid form when looking at their Strokes Gained data over the last 20 rounds on Data Golf.
