Ko is in second position and three behind behind Laura Diaz at the LPGA Tour event in Ohio and Alker finds himself just one shot out of the lead at the Web.Com Tour's Albertsons Boise Open in Boise Idaho.
Alker won earlier in the season and is currently 19th on the Web.Com Tour money list. A top three finish this week will likely be enough to assure him of a return to the PGA Tour next season.
Alker played the PGA Tour for three season in the mid 2000's but has not been able to get back there despite a win on the Web.Com Tour last season. This weekend might change all of that.
Alker is a quiet achiever having won last year and this year and appears to be playing as well now as ever. He qualified for the US Open earlier this season and although he did not make the cut at Pinehurst just getting there was an achievement.
He also qualified for and then made the cut at the US Open last year.
Alker is in third position alone this week, one behind Bill Lunde and Zach Sucher in Boise.
Australians Cameron Percy, James Nitties, Steve Allan, Gavin Coles, Aron Price and Nathan Green all made the cut on the number.
