Both Bryce Harper and Mike Trout were 20 years old when they made the All-Star team in 2012.
Manny Machado will likely be an AL All-Star a week after celebrating his 21st birthday. A 22-year-old Shelby Miller and 23-year-old Jean Segura will probably join him on the NL side of the field this July and for many years to come.
Elsewhere, there are aging veterans who are hoping they'll get their first chance to play in the Midsummer Classic.
The following 10 guys have:
A) Never gone to an All-Star Game,
B) At least 2,500 career plate appearances or 800 career innings pitched, and
C) A WAR of at least 1.0 in 2013 (according to FanGraphs)
Perhaps this will finally be their year.
