It very rarely went that way [pointing straight ahead]," Scheffler expressed during the RBC Heritage pre-tournament press conference.Well, this was not the first time the World No. 1 expressed his frustration with precision. During the Players Championship, which could have been his 3-peat, he shared a similar experience."It was a taxing week for me, but like I said, I haven't had my best stuff this year, but I feel like I'm learning a lot. Each week I feel like I'm improving and continuing to learn," Scottie added further.But there was a very large difference in how he carried himself this time. He made several jokes while detailing what went wrong.And why not? Despite the challenges, Scheffler carded a total of 8-under par, 72, finishing in fourth place at Augusta.After spending precious practice time before the press conference working on his swing, Scheffler's optimism was evident as he looked forward to competing at Harbour Town."I hit some balls before I came over here today. I feel like each day I come to the range, I'm getting a little bit better. Things are starting to feel more the way they should," he shared, showcasing an improvement after weeks of injury frustration."I'm excited for this week. It's a really good test of ball striking, this golf course. You've got to curve it both ways. You've got to hit shots. We're going to get some wind."You have to control spin, control trajectory. I'm looking forward to this week," Sheffler added, expressing his emotions for this week.More Golf: Scottie Scheffler's 'Rusty' On-Course Demeanor Prompts Masters Concerns
