For a baseball player, MLB spring training is like flirting at a bar for a cocktail waitress. It's a necessary function of the job but means nothing about a guy's future prospects with her.
Likewise, the performance of a team or player in spring training doesn't indicate anything about how the regular season may end. There have been teams that looked great in spring training but flopped during the season and vice versa.
Spring training is more like a glorified health club than anything that represents high-leverage competition. It's a means to achieve better performance when the season actually starts.
