UNDATED (AP) – Pittsburgh Pirates third baseman Ke’Bryan Hayes is eager to prove his breakout rookie season was no fluke. Hayes hit .376 with five home runs and 17 doubles in 24 games after arriving in the majors last September. The pop Hayes showed at the plate came as a bit of a surprise to everyone but Hayes, who credits a couple of tweaks to his swing for the power surge. Hayes says he knows teams will adjust this season but he’s confident he can handle the roller coaster that lies ahead.
