Joe Mauer went 3-for-4 in Game 1 of today's day-night doubleheader. That's good. All three of the hits were singles. At face value, that's not so bad. Big picture, though, it's starting to get a little more than troubling. Mauer is slugging .315 this season. The guy is hardly a power hitter, but his career slugging mark is .474.

We ran the numbers, and dating back to last season Mauer has 1 home run in his last 235 at bats -- and none, obviously, in 127 at bats so far this season.

For a while, the rust factor from the DL trip was a viable explanation. But he's been back for a month now. It would be nice to see Mauer take one deep.

We invite your best guess -- heck, even tonight! -- as to when that might happen. Perhaps the winner will even get some sort of excellent prize.
