The 23-year old flame-thrower has had his ups and downs throughout the season and has a very uncharacteristic 3.70 ERA over 56 innings. However, he also has 71 strikeouts and can easily bring a triple-digit fastball each time he takes the hill. The Royals are hoping he can regain his August form in which he allowed just one run over 17.2 innings (15 appearances) as they make a push toward earning a wild card berth this season. Fantasy owners with a Games Started limit should look to Herrera if strikeouts are needed to maintain your place in the standings.","date":"Fri Sep 13"},"fullName":"Kelvin Herrera","seasonOutlook":{"outlook":"Herrera, a hard-throwing right-hander who tore through the Royals' minor league system after being converted to relief in 2011, exploded onto the scene as one of the team's most valuable bullpen assets last summer. His average fastball velocity was clocked highest in the game -- 98.4 mph -- and that gave good balance paired with a changeup more than 10 mph slower (86.9 mph average). Oddly, Herrera was more location/change-of-pace type than someone who tried to overpower everyone, partly because he generated a lot of grounders (57.0 percent rate) thanks to a two-seamer. He's a capable ERA/WHIP helper, and someone who might have a sneaky good holds total.","seasonId":2013,"date":"Thu Feb 21"},"playerRater30DAY":-1.8,"playerRater15DAY":-1.2,"positionRank":81}
