Josh Donaldson took a significant step forward Saturday in his recovery from a strained right calf, running the bases at full speed on a backfield at Florida Auto Exchange Stadium. Donaldson hasn’t run the bases since he strained his calf nearly a month ago, and said he didn’t experience any trouble during the test.

The Blue Jays will wait and see how Donaldson’s calf responds Sunday morning before deciding on a next step. However, Donaldson hopes to play in a minor-league game on Sunday and test his legs even further there. Earlier this week, fellow recovering Blue Jay Devon Travis hit and ran in a minor-league game a day after running the bases on a backfield like Donaldson did on Saturday.

“Everything went really well,” Donaldson said after running the bases. “No problems, no issues.”

Donaldson was originally scheduled to play in a minor-league game on Saturday, taking at-bats but not running the bases. However, that plan was scrapped mid-morning and Donaldson stayed back to test his calf on the base paths.
