Scores on Day 1 of the 147th Open Championship ranged from 5-under 66 to 11-over 82.
The field of 156 players will be cut nearly in half for weekend play at Carnoustie. Here’s how the cut line works in the season’s third major championship:
• After 36 holes, the low 70 players and ties will advance to compete in the final two rounds. Anyone finishing worse than that will get the boot. Only those making the cut earn official money from the $10.5 million purse.
• There is no 10-shot rule. That rule means anyone within 10 shots of the lead after two rounds, regardless of where they stand in the championship, make the cut. It’s just a flat top 70 finishers and ties.
• There is only a single cut at The Open. PGA Tour events employ an MDF (Made cut Did not Finish) rule, which narrows the field after the third round if more than 78 players make the cut. That is not used at this major.
The projected cut line after the first round this week was 1 over par, which included 71 players tied for 50th or better.
