Atlanta ? Kansas City manager Ned Yost won’t hesitate to give the ball to Kelvin Herrera again soon.

Even after a rough outing against the Atlanta Braves.

Herrera (1-1) gave up solo homers in the eighth inning to Jason Heyward, Justin Upton and Dan Uggla and the Royals could not recover in a 6-3 loss to the Braves on Tuesday night.

“He was throwing the ball good,” Yost said. “Location wasn’t very good. A lot of pitches were up and kind of down the middle, but he’s been almost unhittable all year long.”

The Braves have won 10 straight games — their best streak since April 15-May 2, 2000 — while Kansas City has dropped three of four.

Royals starting pitcher Jeremy Guthrie gave his team a chance to win despite allowing a pair of solo homers to Juan Francisco and leaving for a pinch-hitter in the eighth with the score tied 2-2.

But Herrera, who began the game with two saves and 5 1/ scoreless innings this season, fell apart after facing Heyward with one out.

Heyward hit the go-ahead homer with an opposite-field shot into the left-field seats. Upton and Uggla followed to make it 5-2.

“I’ve got all the confidence in the world in that guy,” Kansas City right fielder Jeff Francoeur said of Herrera. “Send him out there tomorrow. I feel he’ll go one-two-three. For him, it was one of those nights.”

Eric O’Flaherty (3-0) allowed one hit and struck out two in a scoreless eighth for the win in relief.

Herrera allowed three hits, four runs and one walk in two-thirds of an inning.

After Francisco walked to chase Herrera, Chris Johnson followed with an RBI single off Aaron Crow that scored pinch-runner Jordan Schafer from second. Luis Avilan recorded the first out of the ninth before seeming to injure his left hamstring. Avilan limped slowly off the field with the help of trainer Jim Lovell and manager Fredi Gonzalez before getting carted off.

Closer Craig Kimbrel finished off the Royals by striking out pinch-hitter Billy Butler, giving up an RBI single to Alex Gordon and retiring Alcides Escobar on a groundout. It was a non-save situation for Kimbrel.

The Royals, who have lost three of four, led 2-1 in the fourth when Salvador Perez reached on Francisco’s throwing error, moved to second on Mike Moustakas’ single and scored on Francoeur’s RBI single.

Except for Francisco, who hit his second homer to make it 1-0 in the second and his third to tie it at 2 in the seventh, the Braves were unable to do much against Guthrie.

Atlanta’s first five batters were a combined 0 for 14 with one walk and five strikeouts against Guthrie.
