Urquidy (undisclosed) was cleared to participate in baseball activities Friday, Jake Kaplan of The Athletic reports.
The 25-year-old was absent from summer camp for undisclosed reasons, but he'll now head to the team's alternate training site to begin prepping for the season. Urquidy figures to require some time to build up to a starter's workload, so it's unclear when he may be able to rejoin the Astros. Framber Valdez is opening the season as the team's No. 5 starter in his place.
