Not sure how any of us in the Brewers' regular, daily beat corps didn't get this, but sure enough, Francisco Rodriguez isn't exactly thrilled with his current role as set-up man to closer John Axford.

OK, we all knew – everybody did – that he wasn't thrilled to come to Milwaukee and not close games, as he had done most of his career. But though he's expressed a desire to close games, he's never come out and said outright he wasn't happy, as he did to Scott Miller of CBSSports.com.

"I'm not fine," Rodriguez told Miller. "They told me I'd have the opportunity to close some games, and we've had 20-some save opportunities since then and I haven't even had one."

On the surface, one could chalk up K-Rod's angst as just a highly-paid ballplayer blowing off some steam and think little more of it. Rodriguez is signed through the end of the season, the Brewers aren't likely to make a play for him in 2012 and, above all else, the guy is getting his job done: 3-0 with a 2.31 ERA in 24 games since joining the team during the All-Star break.

There's no way manager Ron Roenicke is going to change things up at the back of the bullpen. Axford has been practically flawless of late, converting 39 consecutive save opportunities and has a 0.71 ERA in his last 25 outings.

Yes, when the Brewers made the trade, Roenicke said that Axford, who has converted 23 of his first 25 opportunities, and Rodriguez who had a 3.16 ERA and 23 saves with the Mets, would split time at closer. That hasn't happened, but if you were Roenicke, what would you do?

One would assume that Rodriguez will continue with the status quo – would he rather be a closer on an awful team like the Mets or a set-up guy on a potential pennant contender? But even the slightest hint of a rift could derail the Brewers' postseason express.

K-Rod wants to close and he could get his chance Wednesday, when the Brewers face Colorado in the finale of a quick, two-game series. Axford worked two innings Tuesday, so he's unavailable. Rodriguez had better bring his A-game ... if he doesn't, he might never hear the end of it.
