Crash Bag Vol. 18: Trading Cesar

Thank you to Brad for doing this last week, and for being much funnier in the process than I am. It has been a really bad week of results for the major league club, so why not talk about trading their best player so far, and answer some other questions along the way as well.

For now the best place to ask questions is on Twitter, either @ me (@Matt_Winkelman or @CrashburnAlley). But you can also reply in the comments here and I will will have some sort of better way for future mailbags.

@mweintr: Should Cesar Hernandez be traded now, when his value is highest?

It has become trendy to to want teams to keep trading and churning players, always looking for value. This is not the worst strategy when you know you are going to be a non-contender for the remainder of a player’s contract. However, Cesar will turn 27 just over 2 weeks from now and still has 3 more years of control through arbitration. He is currently batting a BABIP influenced .336/.379/.517 with a career high strikeout rate and career low walk rate. History says his power should trend down, and his walk and strikeout rates should trend positively towards his career averages. He is on pace for a 6+ WAR season, which is probably unsustainable, but he should be able to repeat his 4 win season from a year ago, barring an unexpected collapse. That is a really good baseball player, and if you are going to trade someone of his caliber, with his level of remaining control, you are going to want a haul back. Continue reading…

Trying to Understand Cesar Hernandez

This weekend Cesar Hernandez hit two home runs. Two is such a small number in the context of baseball, and most small events like this could be explained as small sample size noise. However, these home runs brought Hernandez to 3 in 12 games. This is Hernandez’s 5th major league season, and in the previous 4 he hit 8 home runs total. The spike is noticeable in the ongoing confusion that is Cesar Hernandez.

The introduction of StatCast has brought a larger voice to the concept that hitting the ball in the air is better than hitting the ball on the ground. This is not a new idea to anyone who has studied basic mechanics and specifically ballistics. The 2016 data bears this out too.

Ground Ball .239 .019

So how does this tie back to Cesar Hernandez? Here is Hernandez’s batted ball data in his time in the majors: Continue reading…
