Ervin Santana, after throwing to hitters - includng Jorge Polanco - on Monday will pitch for Fort Myers on Saturday. He will throw three innings of 45 pitches, whichever comes first. But his velocity on Monday, according to manager Paul Molitor, looked about the same as his previous outing, when he couldn't touch 90.

Polanco is in the lineup for the Miracle tonight, and the Twins want to fast track him to Rochester to see how ready he will be. If they don't like what they see they could DL him when it is time for him to come off the PED suspension list.

Aldalberto Mejia gave up one run over six innings on Monday and is in the mix to start on Saturday against the Cubs. A final decision has not been made, and Molitor said tonight's weather watch could impact that decision.

There is a threat of rain around 5 p.m., so both team moved up their pre-game schedule so they could be done before the storms hit. Not sure how long they will last. Chicago has dodged storms all day like there's a forcefield around the city. We'll see how long it lasts.

This is supposed to be the dream week for the traveling Twins fan -- six games in Chicago against the White Sox and Cubs, followed by three in Milwaukee. A weekend in Chi-Town. Fourth of July in Milwaukee. Two good places for tourists. Two good places to grab a cold one.

At least that's been the Star Tribune spin on the road trip.

No one mentioned any potential challenges, like weather.

As the Twins prepare to open a three-game series at against the Sox, Mother Nature has decided to be among those in attendance.

The potential for a rain delay strongly exists in the afternoon and evening. (Here's your Chicago weather forecast.)

Meanwhile, here are a few quick updates:

Byron Buxton went 1-for-8 with four strikeouts yesterday in a doubleheader and is now batting .154 in seven games for Class AAA Rochester during his rehab stint. Those of you thinking Buxton would make an appearance this week, think again.

The Twins announced the recall of outfielder Jake Cave (pictured above) from Rochester. This will be his third appearance with the Twins this season, and represents the, "different look," Twins manager Paul Molitor touched upon when announcing the demotion of outfielder Ryan LaMarre. Cave will be in the lineup against the White Sox tonight, playing right and hitting eighth.

Cave is batting .265 with five home runs and 27 RBI for the Red Wings.

Cubs righthander Yu Darvish, a free agent target of the Twins and other teams during the offseason, gave up one run over five innings on Monday for Class A South Bend. The numbers looked good, but Darvish reported soreness in his triceps tendon and indicated that he might not be in condition to return to the Cubs this yet. We will see, since Darvish could start this weekend against the Twins in Wrigley Field.

Here are tonight's lineups, with Joe Mauer hitting leadoff and Logan Morrison batting cleanup for the Twins:
