The Rockies' third baseman has hit his way into a spot that isn't going anywhere. Six hits over his last four games — including a triple and two home runs — with strong underlying Statcast numbers. Even adjusting for Coors, the power is legitimate. He was essentially unowned a month ago.

Karros earned Colorado's Opening Day third-base job after an impressive spring training and has quietly become one of the more reliable corner infielders on the fantasy wire. His last four-game stretch has been exceptional — six hits, two home runs, four RBIs, six runs, and a steal — and his underlying contact quality has improved from his early-season profile. The Rockies' offense and Coors Field guarantee volume, and a 23-year-old posting genuine on-base gains is worth the add before ownership crosses 30% this week.
