“The original two-ball alignment mallet with the White Hot insert; face-balanced for a straight stroke and one of the best-selling putters ever made. Cheap and everywhere.”

The 2-Ball turned putter alignment into a punchline everyone got. Odyssey took its 2000-vintage White Hot two-part cast-urethane insert (formulated to mimic the cover of Callaway's Rule 35 ball for soft-but-lively feel) and paired it with a radical elongated mallet stamped with two white circles the size of a golf ball. Line the circles up with the ball behind them and your eye is forced square to the target. Annika Sorenstam won big with it into 2002 and it became the best-selling putter of that year, then arguably the best-selling putter ever made. Reissued repeatedly, most recently in the White Hot OG line, on the principle that a good idea then is still a good idea now.

Widely and repeatedly cited as the best-selling putter in golf history. Callaway's own release names it the best-selling putter of 2002; the 2-Ball design won the 2002 U.S. Women's Open and Annika Sorenstam rode it from late 2001 through her 2002 dominance, and the White Hot insert lineage across Odyssey lines has accumulated ~100 PGA Tour wins including 48 majors. Its footprint is documented across independent golf media (Golf Digest, Golflink, MyGolfSpy), not just enthusiast forums.

Built for the straight-back-straight-through stroke and, above all, for the golfer who struggles to aim. The two circles line up behind the ball like railroad tracks, so it flatters players who chronically set up open or closed. Ideal for high-handicap and recreational putters, seniors, and anyone who values dead-simple alignment over feedback. Poor fit for a strong-arc stroke player who wants toe hang, or a feel purist who prefers the click of milled steel — the soft urethane insert deadens sound.

• Named the best-selling putter of 2002 in Callaway's own release and repeatedly described in golf media as the best-selling putter of all time.
• The White Hot insert is a two-part cast urethane pressed to mimic the cover material of Callaway's Rule 35 ball, tuned for a soft feel that tour players still prefer.
• Won the 2002 U.S. Women's Open; Annika Sorenstam adopted it in late 2001 and used it through her 2002 tear.
• The White Hot insert family has been credited with roughly 100 PGA Tour wins including 48 majors across all Odyssey models using it.
• Face-balanced elongated mallet with two ball-diameter alignment circles — a self-aiming design copied industry-wide.
• Reissued across two decades culminating in the White Hot OG 2-Ball, marketed on '20 years of White Hot.'

Landed as insert putters were displacing pure milled-steel blades at retail, and as Odyssey (bought by Callaway in 1997) was overtaking the putter market — Odyssey putters won 45 worldwide events in 2002 versus 29 for the nearest rival. It competed against Scotty Cameron milled blades, Ping's stainless mallets, and TaylorMade's Rossa line. Its direct descendants are the White Steel 2-Ball, 2-Ball SRT, Versa 2-Ball, O-Works 2-Ball and the White Hot OG 2-Ball still sold today; the alignment concept spawned countless imitators.

Cheap, plentiful, and a genuine bargain in forgiveness-per-dollar. Realistic 2026 private-party value for an original White Hot 2-Ball is roughly $50-$130 on eBay/SidelineSwap depending on wear, headcover, and shaft length; graded reconditioned-retail listings quote around $129 for 'good' condition, which is the top of the honest private range, not a floor. Insert wear/scuffing and a missing headcover knock value down. It does not appreciate — millions exist — but demand stays steady because the design still works.
