Perez will bat fifth as the team's DH against the Twins on Wednesday, Jeffrey Flanagan of MLB.com reports.
Perez has gone 7-for-9 in his first two games of the series, so it makes sense for manager Ned Yost to keep him in the lineup as much as he can. He will also get a much-needed day off behind the plate after starting 43 of the team's first 45 games.
