The Blue Jays selected outfielder Brad Glenn from Triple-A Buffalo on Wednesday. Pillar was hitting .225 with no home runs and two RBIs, and was demoted to Triple-A.
Pillar tossed his bat down the steps leading from the dugout to the clubhouse after Anthony Gose batted for him in the eighth inning Tuesday night against the Yankees.
Pillar then walked the length of the dugout and took off his batting gloves while having a brief and civil conversation with manager John Gibbons.
On Wednesday, Gibbons said Glenn was promoted to increase offensive production. But Gibbons acknowledged that Pillar's antics ''didn't help him at all.''
''This is a team game,'' Gibbons said. ''There's no room for selfish play.''
