it's not gloating over him having one exceptional night that's out of the norm, though. You're implying he's a bad baserunner but he's not, he's well above average. He has a 16.6 UBR for his career, and his 3.2 last year was 21st in all of baseball.
Because he makes slides like this: http://m.mlb.com/video/v33106065/kclaa-aybar-beats-throw-home-on-cowgills-single/?query=aybar
and heads up plays like this: http://m.mlb.com/video/v32977363/tblaa-green-drills-rbi-single-to-wall-in-left/?query=aybar
Every player makes an occasional mistake on the basepaths. It sounds like when you see them from Aybar it's just feeding your confirmation bias.
