Brian Harman started the week as a longshot to win the 151st Open.
Despite a recent surge of low rounds, Harman opened as a 100-to-1 outright betting option.
Just how good was Harman's recent run of form? Kicked off by a 4-under 66 in round one of the Travelers Championship, he rattled off 11 straight sub-69 rounds en route to a trio of top-15 finishes. His score was at least 1.5 shots better than the field average in all of those rounds, the longest stretch of such rounds in his 1122-round PGA Tour career.
