The Texas Rangers face a rotation challenge with the recent reassignment of Gerson Garabito and infielder Jonathan Ornelas to Triple-A. This move comes as Cody Bradford is sidelined due to an elbow issue, prompting the need for new faces in the lineup. The potential replacements for the rotation spot include promising talents like Jack Leiter and Kumar Rocker, both of whom are aiming to secure their place in the starting lineup. Additionally, Dane Dunning and others are also being evaluated to step in as long relievers to support the roster. The Rangers are actively looking to solidify their pitching staff as they prepare for the upcoming season.
