So much of the current star power in baseball is in the outfield, where phenoms like Mike Trout, Bryce Harper, and Yasiel Puig routinely amaze with their spectacular play. However, there are some equally exciting but less-heralded players who make some tremendous contributions to winning. In 2013 two of these players were also outfielders, and they dominated with their arms. One was a traditionally part-time player, and the other was a rookie non-prospect.

However, the jump to 1,355 innings in 2013 coupled with extra time in right field—his 1,042 right-field innings in 2013 were more than double his prior 516 career innings there—allowed Parra to show off his great arm.
