Larnach can be sent to the minors while Kepler can not, and since Kirilloff already has a spot on the 40-man it's not necessary to trade Kepler abruptly. Larnach has had his moments at bat, like a couple of key sac flies that don't show up in OPS, and his stats with men on base are way better than when the bases are empty, but his leading the team in RBI seems more an outcome of opportunity, and others with similar opportunity have been putrid. His defense has been better than I expected. All in all, though, I'd option Larnach if Kirilloff is raking at AAA a week from now - I want better than a .705 OPS from my corner outfielder (not that Max's .741 is markedly better). Basically, it's the move that can be revisited later, versus an irrevocable one.
