Jordan Spieth pairs with Rory McIlroy in third round of the Masters

At 21, Lifetime Longhorn Jordan Spieth went wire-to-wire in an unforgettable and historic 2015 Masters performance to earn his first green jacket at Augusta National. But to keep his green jacket for another year, the 22-year-old Masters veteran will need to fend off another impressive young golfer, 27-year-old Rory McIlroy.

Spieth (-4) and McIlroy (-3) will make up the high-profile final pairing during Saturday's third round of The Masters.

Spieth, who at one point on Friday had a five-stroke lead on the rest of the field, finished with a second-round score of (+2) -- his first over-par finish ever at the tournament.

Spieth, who has led the tournament for six consecutive rounds, will tee off with McIlroy at 1:50 p.m. CT on CBS.

Only one other person has ever held the lead for six consecutive rounds at The Masters. His name? Arnold Palmer -- in both 1960 and 1961. Palmer ended up losing in 1961 to Gary Player.
