Blake Dunn's RBI single in the 10th inning completed a comeback and gave the host Cincinnati Reds a 4-3 walk-off win over the Kansas City Royals on Tuesday night.

Spencer Steer hit two home runs and scored the winning run as the automatic runner for the Reds, who won for the second time in the last six games.

Will Benson's pinch-hit home run to right field off Royals closer Lucas Erceg leading off the bottom of the ninth tied the game at 3-all.

Dunn's game-winning hit, off John Schreiber (0-3), was the only Reds' hit that was not a home run.

Brock Burke (2-2) earned the win with a scoreless 10th.

The loss spoiled a gem by Royals starter Noah Cameron, who retired 20 of the 21 batters he faced. Kansas City has lost seven of its last eight.

Cameron only allowed Steer's first homer, did not walk a batter and struck out eight.

Steer's second home run of the game, a drive to right-center leading off the eighth, pulled Cincinnati to within 3-2. His ninth homer was an opposite field drive into the stands in right-center.

Reds starter Andrew Abbott gave up three runs on five hits in six innings with four walks and five strikeouts.

Steer's first home run of the game, a shot to left-center, came with one out in the fifth after Cameron had retired the first 13 Cincinnati batters.

The Royals took a 3-0 lead in the fourth on a fielder's choice groundout with the bases loaded by Jac Caglianone and a bases-loaded, two-run, two-out single by Michael Massey.

Cameron made an outstanding defensive play for the first out of the third on Dunn's attempt for a bunt single. Dunn bunted the ball between the mound and first, and Cameron, in one motion, picked up the ball with a backhand swipe and flipped it out of his glove first baseman Vinnie Pasquantino.

Reds center fielder Dane Myers made a leaping catch at the wall on Starling Marte's long drive for the second out of the fifth.
