Bubba Watson already has two wins under his belt this year, but he's now in position to add a third. Here's how things look heading into the final round of the Memorial Tournament, where Watson leads Scott Langley by one shot:
What it means: Casey began the day with a three-shot lead but was quickly overtaken by Watson, who birdied five of his first seven holes. Having won earlier this year on classic venues (Riviera and Augusta National), Watson is now in position to win again this week, carding a 3-under 69 despite a closing bogey. He'll have to hold off a strong list of contenders in the final round, though - one that includes the current world No. 1.
Round of the day: Ben Martin barely made the cut after consecutive rounds of 72, but he made the most of his opportunity Saturday with a 7-under 65. A contender earlier this year at Harbour Town, Martin carded five birdies in a six-hole stretch from Nos. 8-13 to spark his round, which moved him up 53 spots in the standings. At 7 under, he'll tee off Sunday in a tie for 11th, five shots off the pace.
Best of the rest: While Bo Van Pelt and Luke Guthrie both shot rounds of 6-under 66, Scott Langley made a bigger move with his 5-under 67. The former NCAA individual champion had four birdies on the back nine, and despite an opening 72 he'll now play alongside Watson in the final pairing Sunday as he looks to win on the PGA Tour for the first time.
Biggest disappointment: Casey had things on cruise control after opening 66-66, but the Englishman bogeyed the first hole of his third round and failed to get things on track from there. He missed several short putts on the back nine, including birdie efforts from close range at both Nos. 11 and 15, and after a closing double bogey he was left with a 4-over 76. Casey was the only player over par Saturday among those still inside the top 18 after three rounds.
Main storyline heading into Sunday: Watson struggled to back up his Masters win in 2012, but he appears to be having no such trouble this time around. He'll be the main attraction during the final round, paired with the relatively inexperienced Langley, but a pair of his fellow Masters champs lurk in Scott (-9) and Schwartzel (-8), not to mention Spieth, who is - believe it or not - in contention yet again.
Quote of the day: "Shooting in the 60s every day is my goal. It's working out so far." - Watson after rounds of 66, 69 and 69.
