DES MOINES, Iowa — Steven Alker topped yet another PGA Tour Champions leaderboard Saturday, shooting an 8-under 64 for a share of the second-round lead in the Principal Charity Classic.

Coming off a victory last week in Michigan at the Senior PGA Championship, Alker played the four par 5s at Wakonda Club in 5 under — making an eagle and three birdies — to match fast-closing Jerry Kelly, first-round leader Kirk Triplett and Brett Quigley at 13-under 131.

Alker is trying to win for the fifth time in his last 12 events. The 50-year-old New Zealander spent the bulk of his career on the Korn Ferry Tour and a few seasons on the PGA Tour and European tour. Last week at Benton Harbor, he closed with an 8-under 63 for a three-shot victory.

Alker birdied four of the first five holes and added another on the par-5 eighth in a front-nine 31, then holed a 20-footer from the fringe on the par-5 13th and made his final birdie of the day on the par-5 15th.

Kelly had six straight birdies in a 66. The birdie run ended on the par-4 18th when he left a 20-footer a foot short.

The 60-year-old Triplett followed an opening 63 with a 68.

Quigley shot 66, making birdies on the final three holes.

Bernhard Langer was a stroke back after a 66. The 64-year-old German star birdied three of the last five holes in a bogey-free round.

Steve Stricker was 8 under after a 67 a week after having to withdraw from the Senior PGA because of a positive COVID-19 test result. 

Fred Couples also was in the group at 8 under, shooting 69.

Defending champion Stephen Ames was 6 under after a 67.
