That's because on Sunday during the final round of the Rocket Mortgage Classic, the 26-year-old was seen taking some time to asses the slopes - possibly using the AimPoint putting technique - on quite a short putt.
Morikawa has five career PGA Tour wins since turning professional back in 2019, but he hasn't won since The Open in 2021.
This season has been a bit of a mixed bag for the California product, who's fallen seven spots down the Official World Golf Rankings to No. 18 since the end of 2022.
So far, he's missed five cuts in 20 events, the most of his career. However, the once World No. 2 has also notched two runner-ups - first at the Sentry Tournament of Champions in January and again this past week in Detroit.
He hasn't been one of the players - most notably Patrick Cantlay - who have been under fire previously for slow-play accusations, but he is one of the pros who seem to be using an AimPoint putting technique, or something similar.
The technique has previously been thrown into the mix with the slow-play discussions as a factor in prolonging the round.
And on Sunday, one Twitter user caught Morikawa and his caddie taking time on what was essentially a tap-in putt.
In the picture, Morikawa's caddie is seen standing in between the hole and Morikawa's ball, seemingly assessing the putt's slope using his feet - an aspect of the popular AimPoint technique.

One reply said it was "one of the signs of the Apocalypse," and another comment just said: "So bad!!"
Morikawa went on to lose to Rickie Fowler on the first hole of the three-man playoff at the Rocket Mortgage Classic, and his nearly two-year win-less drought continues.
Fowler's win was the end of his own lengthy win-less period as it marked his first in over four years.
