I would expect that there will be numerous occasions this year where we will anticipate a heavyweight showdown between Tiger Woods and Rory McIlroy. While neither of them are in the field this week, there will be a main event. It's Lefty v DJ.
I mentioned in the power rankings earlier in the week that they are essentially 1 and 1A this week. I'm not going to try and convince you to take one over the other. That said, I'm going with Dustin Johnson for my one-and-done pick this week and I'm taking Mickelson as my two-and-done.
There are any number of reasons I could justify this strategy, but the truth is that I'm a hedger. I also wouldn't mind having Mickelson in the holster for an event like Riviera next week or possibly August National.
Best of luck with your games this week!
