Major League Baseball has started interviewing big leaguers linked to the Miami PED investigation, and people who have spoken to MLB investigators are convinced there will be at least some suspensions handed down in the explosive case.

MLB is said not to have interviewed the two biggest names connected by allegation to the clinic, Alex Rodriguez and Ryan Braun, but it's apparent baseball powers simply want to make sure they have gathered enough evidence before confronting the two biggest stars named in the probe.

Rodriguez and Braun are the top two reasons this PED case is attracting so much interest, and since they have been in MLB's crosshairs before, some have suggested they may also be viewed as the top two targets. MLB people declined comment on the case but have consistently said they will go wherever the evidence leads, no matter the player involved.

In what could become the first major point of contention in the case with the players union, there is some suggestion that MLB officials believe its Joint Drug Agreement may allow it to announce suspensions before any appeal process in this case since the names have already surfaced publicly. The players union position is that any suspension, as well as the announcement of suspensions, should be stayed until the appeal process is complete.

There is no indication which of the 15 or so implicated players may be more exposed, though on the surface at least there would appear to be more evidence against Rodriguez than Braun. Rodriguez's name is much more prominent in the alleged notebooks of Tony Bosch, the proprietor of the now defunct Miami "wellness" clinic Biogenesis, the business at the heart of the case.

The investigation, which has been going on since spring training, has been painstaking, and perhaps painful for players waiting on a determination. But in light of the fact neither Rodriguez nor Braun has been called, no resolution involving the two big names should be expected in coming days. CBSSports.com reported as far back as six weeks ago that MLB officials were thought to be "encouraged." MLB won't comment on individual players, but it is clear they remain of interest.
