Kubitza was promoted to Double-A Erie on Wednesday, Tom Reisenweber of the Erie Times-News reports.

With Ruben Alaniz moving up to Triple-A Toledo, Kubitza will fill his spot in the Erie bullpen. After a disappointing 2015 campaign with Erie, the 24-year-old has shined in High-A Lakeland this year, allowing only nine runs in 29.1 innings pitched.
