Mina is now 17-under par for the tournament and four-under on the day, one shot ahead of third-round leader Jesper Knnegard of Arizona State. Kennegard, who started Wednesday's action four shots ahead of Mina, is 16-under for the tournament and one-over for the day.
Mina has holes 7-9 remaining to play, while Kennegard still needs to play holes 16-18.
