O'Brien is impressing his new teammates with his displays of power so far in spring training, the Kansas City Star reports.

EDGE Analysis

Eric Hosmer called O'Brien's power "amazing," while Alex Gordon took it a step further and declared it "the best [he's] ever seen." O'Brien hit three homers in the Royals' first four spring games as he starts building his case for a spot on the Opening Day roster, but he's widely considered a long shot to make the team out of camp. In addition to the swing-and-miss issues that have dogged O'Brien and his lack of a defensive home, his two option years remaining are working against him.
