Rivera, 32, came to the Jays in the trade that sent Vernon Wells to the Angels back in January. In 271 plate appearances in Toronto, Rivera hit just .246/.310/.365 with six homers. He split his time fairly evenly between left field, first base, and designated hitter, though he did make a handful of appearances in right field as well.
Many were surprised to see the Jays demote Snider, a long-time top prospect who played well when he was healthy in 2010, after just 99 plate appearances this season. Snider hit just .184/.276/.264 but showed significant improvement in the minors, hitting .333/.403/.488 in 226 plate appearances. Snider was rated as the game's sixth-best prospect prior to the 2009 season, and is still just 23 years old despite having 208 Major League games under his belt.
