The Dodgers announced their updated list of non-roster invitees to spring training. On a team with a roster fairly well set (thanks to last year's in-season moves and the big contracts that so many of the Dodgers carry), it's surprising to see you could make a case for as many as four of these players to actually make the Opening Day roster. Reliever Peter Moylan is a good bet to start the season in the Dodgers' bullpen -- if healthy, something that has been a recurring problem for him the past two years. Outfielder Tony Gwynn Jr. offers some outfield depth and utility man Alfredo Amezaga is versatile, experienced and coming off a batting title in the Mexican winter league (where he hit .344 for Obregon and is currently playing in the Caribbean Series). The toughest competition for a roster spot this spring is likely to be at backup catcher where four non-roster invitees (Jesus Flores, Eliezer Alfonzo, Wilkin Castillo and Ramon Castro) all have big-league experience. One could very well bounce Tim Federowicz back to Triple-A.
