Blixt, Jimenez share early Masters edge

Blixt, who could become the first Swedish man to win a major golf title, opened with two pars and birdied the third before a bogey at the par-3 fourth.
Birdies followed at the fifth and par-3 sixth before the Swede took a bogey at the seventh, but he responded with birdies at the the par-5 eighth and par-4 ninth.
Another birdie at the par-5 13th lifted Blixt, who was playing alongside two-time Masters winner Ben Crenshaw and South Korea's Yang Yong-Eun, to four-under, but a bogey at the par-5 15th dropped him back into a share of the lead.
No first-time player has won the Masters since Fuzzy Zoeller in 1979.
Jimenez birdied the par-5 second and added back-to-back birdies at six and seven to join Blixt on three-under.
Americans Fred Couples, Bill Haas and Kevin Stadler shared third on two-under.
