It’s been a rough week for Bobby Jenks owners. Jenks suffered his second blown save of the week Saturday in Chicago’s loss to the Tigers. Saturday’s outing marked the fifth time in his last six appearances that he has given up an earned run. His ERA is now at 4.33

In a span of two days the Sox have gone from being in first place to possibly being four games out should they lose tomorrow. The question is, how long will Ozzie Guillen stick with Jenks as his closer?

Should Guillen decide to go a different route, Matt Thornton would probably be the choice to get saves on the south side. Thornton has been Chicago’s best reliever all season and currently has a 2.85 ERA and 1.20 WHIP. He also has 49 strikeouts in 41 innings. If he’s available in your league, it would be a good idea to go ahead and grab him.

Here are some other closer situations around the majors worth keeping an eye on.

Baltimore-There is still a good chance that George Sherrill could be traded before the deadline, which is bad news for his owners, as he would probably be moved to a team that has a set closer, such as the Yankees, Cubs, Angels, or Brewers. Jim Johnson would be the favorite for saves if Sherrill is traded.

Los Angeles Dodgers-Jonathan Broxton has been great, but his toe injury could be an issue. Plus, you know how Joe Torre likes to overuse his relievers. Keep an eye on Broxton.

Philadelphia-Brad Lidge has still been shaky since coming of the DL, sporting a 5.87 ERA in July. But Charlie Manuel has shown he has faith in him, so his closer spot should be safe for the time being.

Texas-Frank Francisco has been great for the Rangers this season-when he’s been on the mound. Francisco currently has 15 saves and a 2.28 ERA, but went on the DL for the third time this season on July 20 with pneumonia. C.J. Wilson has picked up saves in his absence.
