The month of June has been defined by big-name call-ups, and although none has been bigger than Stephen Strasburg, let's look at three other teams that have added some prime talent to their roster -- and see whether there is more coming.
• Dubbed "the cavalry" by one member of the Pittsburgh media, the Pirates have added a slew of prospects to the big leagues of late, but none will be bigger than this week's expected arrival of Pedro Alvarez. Is it time to finally be optimistic in Pittsburgh?
• Mike Stanton brings his gargantuan power to the bat, but has the pipeline of young talent in the Marlins system suddenly begun to dry out?
• The best prospect in the Cleveland system, Carlos Santana, is not only the new starting catcher for the Indians but their new No. 3 hitter, as well. There's not much help this year, but some of the top prospects in the system are lined up to fill some major holes.
