Blue Jays catching prospect Travis d'Arnaud tore ligaments in his thumb catching for Team USA recently. J.P. Arencibia has been holding down the fort, but d'Arnaud is believed to be their catcher of the future. Toronto acquired him from Philadelphia in the Roy Halladay trade. If he misses some time this spring -- including spring training itself, as well as part of the regular season -- his ETA in the big leagues is certain to be pushed back.
