Often times I get my player ideas for this column from the bids in AL Tout Wars. Unfortunately, that means my recommendations typically learn toward American Leaguers, rendering National League owners $hit out of luck. My apologies. But you’re in luck! This week actually features a player from each league.
Yesterday, I discussed the hitters who have enjoyed the biggest increases in their batted ball distances this season. The list should mainly be used for validation purposes as for the most part, it should confirm a power spike. Today it’s time to look at those hitters who have experienced the largest declines in their distances. Owners must hope these drop-offs are merely small sample size flukes.
Last week, I discussed the hitters whose average batted ball distances suggest significant HR/FB rate upside. This time, I’ll share a list that is to be used for validation purposes. Is that batter currently enjoying a power spike hitting the ball much further than last year? Let’s find out.
I have essentially stripped the terms “buy low” and “sell high” from my vocabulary, so I now prefer to call the former buy low guys acquisition targets. One would think that offering for a player off to a slow start would have to come at some sort of discount, even if a minor one. And since slow starts are usually just that and have little predictive value for the rest of the season, getting anyone at a discount to his pre-season value should yield a nice profit.
As usual, the easiest way to identify your targets is to calculate the difference between a pitcher’s ERA and SIERA and then sort. Those pitchers with SIERA marks most below their ERAs are typically your targets, though that’s not automatically the case. Often times a pitcher could be carrying an ERA over 7.00, but still sporting a 4.50 SIERA. Sure, he’s been unlucky, but he also hasn’t been very good either! So you still don’t want him on your team.
Today’s deep league wire features a pair of fresh outfielder call-ups. Both were one-time promising prospects, but have struggled at the big league level. Are these two post-hype sleepers?
Yesterday, I took our first look at the batted ball distance leaderboard to identify hitters who could enjoy a surge in HR/FB rate. Today I’ll check in on the potential decliners. This could perhaps be your sell candidates. I’m going to ignore the obvious ones that have still posted strong distance marks, like Bryce Harper at at 35.5% HR/FB rate, backed by a 323 foot distance. Obviously, he’s going to regress, but that big distance suggests a career year in the power department.
We’re not a month into the season, so it’s finally time to start putting the hitter batted ball distance leaderboard to work. Back in late January, I unveiled my xHR/FB rate equation, which included three components, batted ball distance being one of them. Unfortunately, I don’t have the data for angle and standard deviation, so I cannot calculate xHR/FB rate marks yet and share the biggest discrepancies. However, simply looking at batted ball distance could do a reasonably decent job at identifying those who might be in for a HR/FB rate surge or decline. We’ll start with the potential surgers. These are the hitters whose distance is top notch, but for whatever reason, have posted mediocre or poor HR/FB rates.
It’s no secret that CC Sabathia has struggled mightily since 2013. It’s also no secret that his troubles have coincided with a swift decline in fastball velocity. Check out his velocity trend since 2011:
Last season he lost over two miles per hour off his fastball to a mark that dipped below the important 90 mph threshold. And yet despite the obvious signs of decline, I remained stubbornly optimistic, thanks to a still respectable SIERA. I (foolishly?) boldly predicted that Sabathia “reminds us of his glory days and earns top 40 starting pitcher value” this year.
For a change, this week’s pair of recommendations are not the result of injury. One of them could be usable in more than just deep leagues, depending on your specific format, while the other is truly for the deep leaguers.
Yesterday, I dove into the Baseball-Reference S/Str (swinging strike rate) metric and identified those starting pitchers who have enjoyed the biggest surge compared to last season. So naturally, today I’ll check in on the other side of the coin — those starting pitchers who have suffered through the largest decline in swinging strike rate. Obviously, knowing that a pitcher is inducing fewer swings and misses is worrisome, but we’ll see if there’s any hope for a rebound.
