It was early in the season and the Oakland Athletics were flailing away at the plate while manager Bob Melvin watched batting averages, slugging and on-base percentages plummet along the way. The level-headed skipper said all along his young, powerful hitters would eventually put things together. Whether that was wishful thinking or well-placed confidence, Melvin was right. Yoenis Cespedes had his first career four-hit game, including a homer and three RBIs, and the Athletics beat the Minnesota Twins 9-4 on Sunday to complete a three-game series sweep.
