KANSAS CITY, Mo. (AP) Baseball Commissioner Bud Selig and union head Michael Weiner expressed disappointment that the Yankees’ Robinson Cano was booed repeatedly by fans at the All-Star Home Run Derby after bypassing Billy Butler of the hometown Kansas City Royals. Robinson, the AL captain for the derby, picked Detroit’s Prince Fielder, Toronto’s Jose Bautista and the Los Angeles Angels’ Mark Trumbo for Monday night’s event, which Fielder won. “Robinson Cano certainly picked people he thought should be on there,” Selig told the Baseball Writers’ Association of American on Tuesday. “While I understand Kansas City and I understand the whole Billy Butler thing, I really felt very badly last night.”
