Kansas City shortstop Bobby Witt’s Jr.’s throwing error led to Cleveland scoring three runs on an infield grounder in the seventh inning in the Guardians’ 8-5 win over the Royals on Tuesday night, the first matchup this season between the AL Central’s top two teams.

The Guardians trailed 5-0 in the fourth before storming back to win the three-game series opener and push their division lead to five over the Royals.

Witt clobbered a pair of two-run homers totaling nearly 1,000 feet, but his errant throw in the seventh swung the game to Cleveland.

“I made a mistake,” Witt said. “It cost us the game.”

After Tyler Freeman‘s homer tied it 5-5 for the Guardians and chased Royals starter Seth Lugo, Cleveland loaded the bases on a fielder’s choice and two walks — one by Sam Long (0-1) — with two outs when David Fry hit a grounder up the middle.

Witt gloved it to the right of the base and initially tried to beat Josh Naylor to second for a force. When Witt realized he couldn’t get the sliding Naylor, he unleashed a wild throw that first baseman Vinnie Pasquantino had no chance of getting.

The ball wound up in the photographer’s pit, and because Naylor had already gotten to second base, he was awarded third and home.
