Jesse Winker was having a strong season in 2018 for the Cincinnati Reds before he had to shut things down in July due to a nagging shoulder injury. The rookie outfielder was hitting .299 with a .405 on-base percentage and a .431 slugging percentage through 89 games played. The average and the ability to get on base he showed were high level skills. His power, though, it was below-average. Still, the overall offensive package was strong. So strong that Jonah Keri of CBS Sports has pegged Winker as a potential breakout difference-maker in 2019.
It was, and is the power that held Jesse Winker back from being a legitimate offensive force in 2018.
