Within a short span on Thursday afternoon, Bueno learned that the Braves were optioning him to Triple-A Richmond and that Major League Baseball had issued him a three-game suspension and levied an undisclosed fine for intentionally throwing a pitch near Cubs outfielder Alfonso Soriano's head.
Bueno was ejected in the ninth inning of the first game of Wednesday's doubleheader after he threw a pitch that went behind Soriano, barely missing the All-Star outfielder's head.
Soriano irritated his teammates, and possibly Bueno, when he drilled a line drive off the left-field wall in the eighth inning and slowly made his way toward first base while admiring the drive. His actions limited him to a single and forced him to issue an apology to his teammates.
Bueno, who was making his Major League debut, had been promoted from Richmond on Aug. 4. The 27-year-old Cuban left-hander has appealed his fine and suspension.
