Urias (shoulder) threw a bullpen session Monday, touching 91 mph with his fastball, Bill Plunkett of The Orange County Register reports.
Urias hasn't pitched at the big-league level since last May after undergoing shoulder surgery. His fastball averaged 93 mph prior to his injury, so it's a good sign that its velocity continues to climb, though he's still not back to his former self. He reportedly could be making rehab appearances in July, putting a return in August on the table.
