As the final putt fell on Troy Matteson's first-round 61 to lead the John Deere Classic, the low round to this point in the year on the PGA Tour was again challenged at TPC Deere Run.
Matteson's effort tied 61s by Ryan Moore and Robert Garrigus, both shot at the Nicklaus Course at PGA West during the Humana Challenge (the erstwhile Bob Hope Classic).
The opening round by Matteson marks the fourth consecutive year where a round at the John Deere Classic challenged the lowest of the year on Tour.
Matteson tied the low round of the year on Thursday. A year ago, Chez Reavie shot 62 to tie the second lowest round of the year. Only then-amateur Patrick Cantlay's second-round 60 at the Travelers Championship was lower.
In 2010, Paul Goydos' 59 tied for low round of the year with Stuart Appleby's Greenbrier-winning final round. Steve Stricker nearly matched it that day, shooting 60 as defending champion.
When Steve Stricker began his run at the John Deere Classic in 2009, he shot 61 to tie the second lowest round of the year.
Of the tournaments in the first six-plus months of the PGA Tour schedule, the Humana Challenge has produced the most rounds in the top two lowest through the John Deere Classic. The home to "golf in a dome" has yielded six such rounds. The John Deere Classic, however, is just behind it with five - and three rounds to go this week.
