As you probably know by now, Collin Morikawa switched putters after the first round of The Masters, and he ultimately went on to finish T3.

The putter was far from the only change he made last week, however, and his bag is continuing to change this week at the 2024 RBC Heritage.

On the range of The Masters, Morikawa worked closely with Adrian Reitveld, TaylorMade’s Senior Manager of Tour at TaylorMade, to find the perfect driver and 3-wood setups.

Morikawa started off 2024 by switching into TaylorMade’s Qi10 Max driver, but since went back to his faithful TaylorMade SIM – yes, the original SIM from 2020. Somehow, some way, it seems Morikawa always ends up back in that driver, which he used to win the 2020 PGA Championship, and the 2021 Open Championship.

At The Masters, however, Rietveld said the duo found the driver head that allowed “zero compromise” on Morikawa’s preferred fade flight and spin. To match his preferences, they landed on a TaylorMade Qi10 LS 9-degree head, and the lie angle is a touch flatter than his former SIM.

“It’s faster than his gamer, and I think what we found is it fits his desired shot shape, with zero compromise” Rietveld told GolfWRX.com on Wednesday at the RBC Heritage.

Then, to replace his former SIM rocket 3-wood, Morikawa decided to switch into the TaylorMade Qi10 core model 13.5-degree rocket head, with an adjustable hosel.

“He likes the spin characteristics of that head,” Rietveld said. “Now he’s interesting because with Collin, you can turn up at a tournament, and you look at his 3-wood, and he’s changed the setting. One day there’s more loft on it, one day there’s less loft on it. He’s that type of guy. He’s not scared to use the adjustability of the club.

“And I think he felt our titanium head didn’t spin as low as his original SIM. So we did some work with the other head, just because he liked the feel of it. It was a little high launching, so we fit him into something with less loft. It’s a naughty little piece of equipment.” 

In addition to the driver and fairway wood changes, Morikawa also debuted his new “MySymbol” jersey No. 5 TP5x golf ball at The Masters. Morikawa’s choice of symbols is likely tied to his love of the Los Angeles Dodgers baseball team.

Not enough changes for you? There’s one more.

On Wednesday at the 2024 RBC Heritage, Morikawa was spotted with a new TaylorMade “Proto” 4-iron in the bag. If you recall, it’s the same model that Rory McIlroy debuted at the 2024 Valero Texas Open.

According to Morikawa, the new Proto 4-iron will replace his old P-770 hollow-bodied 4-iron.

“I used to hit my P-770 on a string, but sometimes the distance would be a little unpredictable,” Morikawa told GolfWRX.com. “This one launches a touch higher, and I feel I can predict the distance better. I know Rory replaced his P-760 with it. I’m liking it so far.”
