Overview

• Harrington posted consecutive 67s and Cink fired a second-round 66 to reach six-under-par 134 and top the leaderboard.
• Their three-stroke cushion follows a cut at five-over par that ended the weekends of Bernhard Langer, Angel Cabrera and other senior major champions.
• The East Course’s 6,000-foot elevation and mountain-influenced slopes have produced few under-par rounds, making distance control and green reads vital.
• David Toms’s three-under-par winning total in 2018 serves as an early benchmark for this year’s leaders, who are three strokes lower through 36 holes.
• With a $4 million purse on the line, Harrington pursues a second senior major title and Cink seeks his first U.S. Senior Open victory over the weekend.
