Cauley entered Thursday's game as a pinch runner and stole a base in a 4-3 loss to the Mariners.
Cauley, who has a history of stealing bases in the minors, stole his first bag as a major leaguer. He's served in a niche role since returning as part of the Rangers' roster expansion. This was his fifth appearance since the recall, with four of them coming as a pinch runner and one on defense during a blowout loss. He's yet to have a plate appearance this month.
