Is Catalon participating in spring training?
I believe you can see Catalon at the :15 second mark of that video. Kyle Allen walks in front of the RBs as Dillon Birden runs in the foreground. He passes in front of #2, which is Catalon, right before the cutaway.
JD has also been saying that the coaches have told him that the Catalon rumor is completely untrue.
