Augusta: Bubba Watson birdied the seventh hole at Augusta National on Friday to take a share of the lead in the second round of the Masters.
The champion two years ago opened with six straight pars before moving level on four under with overnight leader Bill Haas, who was not due out until later in the afternoon.
Australian March Leishman briefly held the overall lead at five under after three opening birdies, but back-to-back birdies at four and five pegged him back on another day of clear blue skies and warm sunshine at Augusta National.
Also at three under were Kevin Stadler, after three holes, and Swede Jonas Blixt, after two.
Much of the day's focus though was on the late starters with leader Haas due out at 1715 GMT.
Defending champion Adam Scott, also one stroke back from Haas, was in the penultimate grouping at 1748 GMT with Rory McIlroy (71) the last man to tee-off in the company of Jordan Spieth (71) and Patrick Reed (73).
Three-time former champion Phil Mickelson was in danger of missing the cut for just the second time in 22 appearances at Augusta National following a first round of 76.
