KANSAS CITY, Mo. — Kendrys Morales hit a walk-off two-run homer with two out in the 13th inning and the Kansas City Royals overcame a rare blown save by Wade Davis to defeat the Atlanta Braves 4-2 on Sunday.

The Royals took two of three from the last-place Braves after losing their five previous series. The Braves lost for the 18th time in 23 games and have won only one series this season.

Alcides Escobar, who had four hits to match his career high, singled before Morales’ blast off Jason Grilli.

The Royals used nine pitchers, tying a club record for one game, with Chien-Ming Wang (2-0) picking up the victory. Lefthander Eric O’Flaherty (0-3), the sixth of seven Braves pitchers, took the loss.

The Braves rallied to tie it with two runs in the ninth off Davis, who blew his first save since July 12 against Toronto, and was 8 for 8 in save situations this year.

Mallex Smith and Erick Aybar had run-producing singles off Davis. Ender Inciarte led off the inning with a single and then Davis walked Chase d’Arnaud.

Royals rookie lefthander Scott Alexander allowed one single and struck out four in three scoreless innings after Davis’ inning.

Eric Hosmer, who is hitting .388 against righthanders, singled home Alcides Escobar in the Royals first. Escobar led off the inning with a double.

Jarrod Dyson opened the eighth with a double and scored on Escobar’s single to finish the afternoon for Braves starter Matt Wisler after 116 pitches. Wisler allowed two runs on eight hits, walked none and struck out seven.

Joakim Soria, the fifth Kansas City pitcher, worked out of a jam in the seventh when he yielded a leadoff double to d’Arnaud. Smith popped up a bunt attempt and d’Arnaud was thrown out by Escobar when he tried to take third on pinch hitter Kelly Johnson’s grounder.

Hosmer, who had doubled, was thrown out at the plate to end the Royals’ sixth when he attempted to score on Salvador Perez’s single to left.

Lefthander Danny Duffy, who replaced the injured Kris Medlen in the rotation and was making his first start, threw three innings, allowing one hit, struck out five and walked two before reaching his pitch limit. Duffy, who made 24 starts last season, began the season with 16 relief appearances.

DIFFERENT LINEUP

Royals LF Alex Gordon hit second for the first time. He batted fifth 11 times and sixth 25 times in the first 36 games. Jarrod Dyson made his second start in center as Lorenzo Cain, who had a nine-game hitting streak, got the day off.

DOWN UNDER FLAVOR

Peter Moylan, who faced four batters, became the fourth Australian-born player to appear for the Royals. The others were Justin Huber, 2005-07, Graeme Lloyd, 2003, and Liam Hendriks, 2014.
