Consider these two players.

Player A: .291/.349/.470 11 HRs, 30 RBIs, 41 runs, .353 wOBA, 125 wRC+, .820 OPS

Player B: .289/.364/.471 11 HRs, 34 RBIs, 52 runs, .360 wOBA, 124 wRC+, .835 OPS

Player A is Miami Marlins outfielder Derek Dietrich. Player B is former Marlins outfielder and current Milwaukee Brewers outfielder Christian Yelich.

After jettisoning Yelich this offseason in a trade to Milwaukee, the Marlins, in part, replaced him with Dietrich, who is having an almost identical season. It is a big improvement over his .324 wOBA and wRC+ 99 season of a year ago, in which he hit just 13 homers in 464 plate appearances. But is it for real?

Dietrich is currently sporting a .354 BABIP, which is quite a bit higher than the league average of .291, and he's doing it with an increase in his ground-ball rate (36.5% last year to 39.2% this year) and a decrease in his fly ball rate (40.7% to 34.9%).

Dietrich is having a great season, but this might be a good time to sell-high on him for a more established fantasy player you can trust a little bit more.
