Houston Astros pitcher Dallas Keuchel spent the second half of the season and the playoffs pitching through a significant foot injury, according to a report.

The Astros left-hander actually required a walking boot once the season ended, though no surgery was required and he is expected to be at full strength for spring training.

Sources told ESPN’s Jerry Crasnick that Keuchel had battled plantar fasciitis, while the Astros themselves characterized the issues as a “minor” foot sprain.
