Washington Nationals shortstop Trea Turner may not be having the kind of offensive season one would have expected out of him, but that is precisely why this is a good buying opportunity.

Sure, his batting average (.254) is 30 percentage points lower than last year's clip (.284), but his on-base percentage (.339) is actually a tiny bit better than last year's (.338). He is striking out a lot more -- 11.1% this year, compared to 6.7% last season -- and his power has gone away (.451 slugging percentage last year to a .387 mark this season).

However, he is still stealing bags, with 18 so far this year, and it's clear he's been the victim of some bad luck. He has a BABIP of .294, which is just below league average, but it's pretty low for a speedy player who has hit about the same amount of line drives (16.6%) as last year (14.8%), yet has lost 30 percentage points off his batting average. It's also encouraging that his hard-hit rate, according to Fangraphs, is 34.8%, up from 26.7% a year ago.

Many owners may be down on Turner, so now is a good time to snag a high stolen-base guy whose offensive numbers should improve.
