Offered here is a Seve Ballesteros autographed and used golf ball from Seve's last competitive professional tournament. Seve famously participated in the PGA Tour for the final time at the 2007 Masters Tournament. He then competed in his only (and last) Champions Tour event at the 2007 Regions Tradition (then called Regions Charity Classic). His walking scorer during that tournament obtained this tournament-used ball from Seve Ballesteros, and had Seve autograph it. After that tournament, Seve would not tee it up in another PGA Tour or Champions Tour event, and only a few years later Seve would be taken from us forever.
