The Toronto Blue Jays will option infielder Lourdes Gurriel Jr. to Triple-A Buffalo following a rough start to his 2019 season, a source told Keegan Matheson of Baseball Toronto.

Gurriel was pulled from Sunday's 8-4 loss to Tampa Bay in the fourth inning shortly after making a throwing error at second base on what should have been a routine play. It marked the second straight game that Gurriel committed an error at second, and he hasn't looked comfortable playing the position all season.

Manager Charlie Montoyo confirmed postgame that he removed Gurriel because of the error.

"He's a young kid struggling mentally," Montoyo said, according to Sportsnet's Hazel Mae. "Yes, that's why we took him out of the game."
