While we’ve seen this in our comment section for a few days, in case you missed it…
The International League Rosters will expand to 25 players for the 2012 season.
First noted by Kram and the original source being the Buffalo Bison’s Website:
The National Association of Professional Baseball Leagues today announced that the active roster limit for teams in the Triple-A and Double-A classifications will be raised to 25 players for the 2012 season.
This will certainly benefit the IronPigs over the long haul as we look back to players like Tagg Bozied riding the Disabled List due to not enough roster spots available.
The real question is, “How will it be used?”
I’ve found it true in life, the more space you have… the more you tend to accumulate. While this may allow another player at the AAA level, I think they may still use the “Valendia Clause” to keep a player around rather than release him.

Well, it’s one more bench player who can pinch hit in close game. Or, an extra arm if you’ve got to use pitchers for double-headers and/or extra-inning games. I bet Mr. Sandberg is in favor of it–gives him a little more flexibility. As Matt Provence pointed out on Twitter, helps the NL teams a bit more with switches and whatnot.
