Aceves was pitching for the Yankees in Triple-A at the time of his suspension, after being sent down with a 6.52 ERA in 10 appearances for the Yankees.
He has always had an impressive arsenal, but his quirky behavior seemed to overshadow his abilities. That he was non-tendered by the Yankees after three years in the major leagues with a 14-1 record and 3.21 ERA was only the beginning.
Here's a brief rundown of weirdness from Aceves' time in a Red Sox uniform:
August 2012: Aceves was suspended three games after an alleged incident in the clubhouse when he argued with then-manager Bobby Valentine over his usage. This is a poor first example, considering this is actually a sane thing for him to do.
February 2013: Aceves barely threw the ball in a live batting practice session during spring training, earning a talking-to from pitching coach Juan Nieves and manager John Farrell and setting a bad tone for the season. Aceves was reportedly mad that another pitcher threw his session before him.
July 2013: Aceves pitched one inning of relief, mysteriously didn't come out for a second, and was banished from the big-league roster. Boston went on to win the World Series.
