KANSAS CITY, Mo. (AP) — Josh Walker balked home the winning run in the 10th inning and the Kansas City Royals rallied past the New York Mets 7-6 on Tuesday night for their season-best fourth straight victory.

Hours after the retooling Mets traded star pitcher Justin Verlander and two other players to cap a stunning deadline selloff, they blew a 6-4 lead provided by rookie Francisco Álvarez's two-run homer in the top of the 10th.

Bobby Witt Jr. hit an RBI double in the bottom half and MJ Melendez tied it with a run-scoring single off Brooks Raley (0-2).

Following a two-out throwing error by rookie third baseman Brett Baty, Melendez scored when Walker balked with the bases loaded to give last-place Kansas City (33-75) its sixth walk-off victory.

Walker was recalled from the minors earlier in the day.

Carlos Hernández (1-6) worked one inning for the win.

Pete Alonso hit his 31st homer for the Mets and added an RBI single in a three-run eighth that gave them a 4-3 lead.

Freddy Fermin’s sacrifice fly off Adam Ottavino in the bottom half tied it.

Kansas City stole three bases in the seventh and scored twice to grab a 3-1 lead. Pinch-runner Dairon Blanco stole third and scored on Álvarez’s throwing error before Maikel Garcia added an RBI single off Trevor Gott.
