According to a tweet from Rob Biertempfel, infielder Chase d’Arnaud’s left thumb injury, which has kept him out of action since late last week, is a torn ligament that may require surgery. This could keep d’Arnaud out for a considerably longer stretch at an inopportune time for him. He’s trying to regain prospect status after struggling to a 252/325/383 line in AAA last year. He’s currently competing for a utility infielder job with Brandon Inge, Josh Harrison, Ivan De Jesus, Jr., and Jordy Mercer. An extended absence could leave d’Arnaud in a tough spot on the depth chart.
