Tsao back to the DL, Ambiorix struggles, Wood to close?

While I hate to see this site exclusively focused on the closing situation for the likes of the Rockies and Royals and Cubs, that's where the action has been lately.

In Colorado, Chin-Hui Tsao is back on the DL with an inflamed right shoulder - the same problem that sidelined him earlier in the season. Brian Fuentes will close games until Tsao returns.

In KC, Ambiorix Burgos has really struggled in his last two outings, and has watched his ERA shoot up from 1.35 to 8.31. (Now that's struggling!) Burgos has shown flashes of brilliance, but has been rocked twice after going 2.2 scoreless for a win on May 8 vs. the Orioles.

On both sides of Chicago, no one knows who is the closer. For the Sox, it's whoever Guillen calls on for a particular day, and more often than not, Shingo & Hermanson have gotten the job done. Hermanson has picked up saves in 6 of his last 7 appearances, and Hermanson and Takatsu both have notched 8 saves. Damaso Marte has also featured into the mix, especially when lefties are due up in the 9th.

On the northside, everyone's waiting for Joe Borowski to return. He tossed another scoreless inning at AAA on Saturday... it's been a while since a Cub reliever has done that. Meanwhile, the Cubs have downplayed persistent rumors that Kerry Wood may be moved to the pen for the balance of the season. Sorta. Pitching coach Larry Rothschild's non-denial denial went something like this: "If you're going to do that, you're going to do it the rest of the year. That would be a major decision. First we have to get him healthy to talk about that."
