Royals recalled RHP Kelvin Herrera from Triple-A Omaha.
Herrera dominated during his 10-day stay in the minor leagues and should immediately return to setup duties in Kansas City. The hard-throwing right-hander has a cool 3.04 ERA in 106-plus career major league innings.

Royals optioned RHP Kelvin Herrera to Triple-A Omaha.
It wasn't too long ago that Herrera was threatening Greg Holland for the closer role, but he has struggled to keep the ball in the ballpark this season, surrendering eight home runs in just 20 1/3 innings. He'll attempt to straighten things out in the minors.

Kelvin Herrera allowed four runs, including three solo home runs, to the Braves on Tuesday.
It was Herrera's first hiccup of the season, and what a hiccup it was. Herrera was taken deep by Jason Heyward, Justin Upton and Dan Uggla in the eighth inning of a game that was tied when he entered. His use in the eighth inning, coupled with his ineffectiveness in the appearance, should pour some cold water on the idea that he's a looming threat to Greg Holland as the Royals closer.

Kelvin Herrera earned his second save of the season in closing out the Royals' 3-0 win over the Twins on Wednesday.
Herrera subbed in for regular closer Greg Holland, who earned his second save on Tuesday. Although manager Ned Yost has said he's sticking with Holland, it's hard to overlook what Herrera has done this season. The 23-year-old has struck out 10 batters without allowing a run in 4 1/3 innings thus far, and he's a perfect 2-for-2 in save conversions. Holland may still have the title for the time being, but any more stumbles and Herrera is ready to pounce.

Kelvin Herrera earned his first save of the season Sunday in the Royals' defeat of the Phillies.
Herrera entered the game to clean up a mess that closer Greg Holland helped create, which suggests that there may be a ninth-inning controversy brewing in Kansas City. Herrera has one of the hardest fastballs in the sport and posted an excellent 2.35 ERA, 1.19 WHIP and 77/21 K/BB ratio across 84 1/3 innings last season. He can be an elite closer right now.

Kelvin Herrera has a 2.59 ERA, 1.12 WHIP and 62/13 K/BB ratio through 66 innings this season.
Herrera also boasts the best fastball velocity in the majors this year, with an average 98.6 mph heater. The 22-year-old has a bright future as a late-innings reliever.

In his major league debut on Wednesday, Kelvin Herrera surrendered three runs on two hits over one inning.
The youngster has a bright future in baseball, but it wasn't in the cards tonight. After hitting the first batter he faced, Herrera yielded a double, followed by a three-run homer with two outs. He likely will compete for a bullpen job next spring.
