KANSAS CITY, Mo. (AP) — Salvador Perez hit a line drive, three-run homer run to break open a close game and finished with four RBIs, leading the Kansas City Royals to a 7-3 win over the Boston Red Sox.

Perez’s blast in the seventh inning appeared to hit the wall below a railing in left field. The play was reviewed and the original call stood.

The call prompted Boston manager Alex Cora to argue with home plate umpire Bill Welke, who tossed Cora.

Bobby Witt Jr. broke a 3-all tie with an RBI single prior to Perez’s home run. Taylor Clarke (3-1) earned the win, despite blowing the lead in the top of the seventh.

Darwinzon Hernandez (0-1) took the loss, allowing four runs in the seventh.
