By loose definition, a breakout player is one that has a season-long performance that really stands out. A performance that we have never before seen the likes of from a particular player.
In 2012, the Padres' Chase Headley belted 31 home runs and led the National League with 115 RBI. Headley had a total of 36 home runs and 204 RBIs in five seasons with the Padres.
Of course, rookies can also have breakout performances. Just look at the Angels' Mike Trout in 2012. His remarkable campaign was as good as many major league veterans can hope for, let alone the fact that he was a 20-year-old rookie. A 30-30 season, which didn't even start until the end of April, was more than enough to earn him Rookie of the Year honors in the American League.
As the latest rendition of the World Baseball Classic comes to an end, this is a chance to look back at some standout performances from players that come from all over the world. Some of these players currently belong to major league organizations, while others could be on the horizon given their success in this year's tournament.
And while major leaguers David Wright, Robinson Cano and Justin Morneau had brilliant showings in the Classic, we will not consider them "breakout" because their prowess has already been established in their MLB careers. Thus, there won't be any players from Team USA or Team Dominican Republic on this list.
