Much of the focus as baseball heads into the second half is on the possible suspensions of Alex Rodriguez, Ryan Braun and a handful of All-Stars implicated in the Biogenesis performance enhancing drug scandal. Puigmania, a Pirates revival and one impressive power show in Baltimore may shift the gaze back onto the field, where there will be a lot to watch headed down the stretch of the regular season. Fans who have been celebrating Mariano Rivera at every stop of his farewell tour should get a chance to watch returning stars Derek Jeter, Chris Carpenter, A-Rod and even Manny Ramirez after a first half dominated by 20-somethings.
