- Tiger Woods made his long-awaited comeback on Thursday, and marked the occasion by handing his playing partner Justin Thomas a tampon, seemingly suggesting that he plays like a woman, after outdriving him at the Genesis Invitational.
- The 15-time major winner was playing his first competitive round in seven months after an injury lay-off but he showed no signs of rustiness as he hit a two-under-par 69.
- It was his driving that stood out during the opening round as he consistently struck his tee shots further than Thomas and Rory McIlroy.
