MESA, Ariz. (AP) — New baseball commissioner Rob Manfred says addressing the Oakland Athletics’ desire for a new ballpark is a top priority, though he’s unsure what influence his office can have on the matter. Manfred, who replaced Bud Selig in January, met with A’s players Monday as part of his spring training tour. He later spoke with reporters and said that he has had talks with A’s owner Lew Wolff and Oakland mayor Libby Schaaf.
