Here are two things to watch out for as the Twins prepare to face White Sox lefthander Carlos Rondon , perhaps their top pitching prospect.

1. Miguel Sano's hamstring. Sano injured his hamstring during the last road trip, forcing him out of one of the games last weekend against Houston. The Twins told Sano to take it easy on the hammy, but then they grew concerned last night when they watched him run the bases rather gingerly. Is that his version of throttling back, of is it a sign of a bigger problem? Twins manager Paul Molitor planned to talk to Sano to make sure he can continue as the designated hitter.

UPDATE: When asked how his hamstring is, Sano replied, ``Bad." He actually had a MRI on it today as a precaution. But he's still in the lineup as of now, and said he's going to run the bases the same way he did last night - very carefully. Twins manager Paul Molitor adnmitted he's a little nervous sending the rookie out there. Don't blame him. But he can hit.

2. Glen Perkins' back. Perkins got the save last night but did give up a run. He seemed to move well, but could not get to first base in time to take a throw from Joe Mauer. Mauer tried to tag Adam Eaton but was late. We'll have to make sure Perkins is good to go as well.

UPDATE: Molitor said Perkins has not reported any problems with his back since returning to the bullpen. He did say a handful of his pitches last night weren't where they needed to be. Rust? We'll see.

The Twins media relations staff points out in today's notes that the Twins have batting .310 in their last five games against lefthanders. That's potentially a good sign for tonight. Eduardo Escobar is on a tear, batting .391 with eight doubles and four home runs over his last 12 games. That's potentially a good sign for Eddie the Stick.

Will post the lineups here after we meet with the manager.

Whoa, here come the lineups now. Sano, who has been named AL rookie of the month for August, is in there at the cleanup spot. So his hamstring is not an issue. Sano hit .278, blah, but hit seven doubles and nine home runs while driving in 26 runs over 27 games.
