You can see why they've been playing Der Kid at 1B as well as the outfield. With Eddie Rosario and Aaron Hicks both hitting now, and Byron Buxton coming back to CF, there's no regular spot for Max Kepler in the outfield. He's too much like another Rosario, which is actually a good thing, but we already have one. Fact is, Joe Mauer's bat doesn't fit a power position like 1st base. Kepler's not a big home run hitter either at the moment, but his numbers keep getting better, and it's looking like his power will continue to develop. With all those triples, we know Kepler's got serious speed, too. Sounds like an offensive upgrade, unless/until Kennys Vargas starts really mashing the ball in AA. Having good young prospects is always a positive sign, even if it means pushing aside former superstars like Mauer. The game has always belonged to the 20-somethings, with just a few grizzled 30-somethings to provide mentoring and leadership. Mauer can still play, but right now I don't see how Kepler wouldn't be an improvement at 1st base.
