The post-Masters whirlwind finally caught up to Jordan Spieth.
In his first competitive round since a record-setting performance at Augusta National, Spieth opened the RBC Heritage with a 3-over 74. The score left him eight shots behind co-leaders Matt Every and Graeme McDowell and in danger of just his second missed cut of the season.
After a record 28 birdies last week, Spieth made his lone birdie on the par-5 15th hole. That tally came after a watery double bogey on the par-3 14th, and Spieth found only eight of Harbour Town Golf Links' 18 greens in regulation.
"There's no excuses," Spieth told reporters. "I should have played a better round today."
Spieth's Masters win capped a torrid stretch, one that included two wins and a pair of runner-ups in his last four starts, and the 21-year-old has six top-10 finishes in his last seven starts. His missed cut at the Farmers Insurance Open remains his lone finish outside the top 20 since he opened the season with a T-35 finish at the WGC-HSBC Champions in November.
Spieth became the first Masters champ to tee it up at Harbour Town since Zach Johnson in 2007, and a bevy of media interviews in recent days appear to have taken their toll. While Johnson finished sixth that year, Spieth was tied for 95th upon completing his opening round.
Spieth has finished inside the top 15 in each of his two prior trips to Hilton Head, and his 74 tied his career high at Harbour Town. After this event, Spieth will have a week off before heading to San Francisco for the WGC-Cadillac Match Play Championship.
