2023 MLB playoffs: X-factors for ALCS and NLCS, from how to pitch to Yordan Alvarez to stopping stolen bases

After a couple of days off, Major League Baseball’s postseason will resume on Sunday, when the Houston Astros and Texas Rangers kick off the American League Championship Series. The Philadelphia Phillies and Arizona Diamondbacks will then start the National League’s identical on Monday.  Before the ones collection can get underway, we right here at CBS Sports sought after to spotlight two X-factors that might decide each and every pennant winner.

You may assume that “X-factor” is a nebulous time period that will get thrown round some distance too steadily this time of the 12 months as an excuse for the creator to discover subplots they may another way lack the distance or justification to get into. You could be 100% proper about that. Creative liberty, what an incredible factor.

Now, onto the great things.

ALCS: Rangers vs. Astros

X-factor No. 1: Breaking balls

Generally talking, there are 3 varieties of “X-factor” eventualities: 1) when a energy meets a weak spot; 2) when a weak spot meets a weak spot; and 3) when a energy meets a energy. The final one applies right here.

During the common season, the Astros threw the fifth-highest charge of breaking balls within the majors. (The “breaking ball”classification contains sliders, curveballs, and sweepers, for the ones questioning.) The Rangers’ lineup, in the meantime, posted the absolute best OPS within the AL towards breaking balls. Which energy will finally end up successful out right here? That’s the place the intrigue lies.

Without overstating issues, this actual X-factor may turn into vital overdue in video games. The Houston pitchers perhaps to junk mail their breakers had been all relievers: nearer Ryan Pressly and right-handers Phil Maton and Bryan Abreu. Each threw a minimum of 58% breaking balls throughout the common season. Starters Justin Verlander and Cristian Javier had been each over 35% as smartly.

On the Rangers aspect, their most sensible performers towards breakers are precisely who you may be expecting: Corey Seager, Adolis García, and Marcus Semien. Each of the ones 3 had an OPS over .800 towards that pitch circle of relatives throughout the common season. Some in their regulars actually struggled towards breakers, on the other hand, giving Houston’s pitching group of workers some doable wallet to exploit this collection.

To wit, check out the breaking ball OPS by way of Texas’ maximum just lately used beginning 9:

We’ve observed the Astros take a extra competitive means with their breaker utilization up to now. Lance McCullers Jr. famously threw 24 consecutive to shut out the New York Yankees within the 2017 ALCS:

The Astros won’t decide for as excessive of a technique this collection. But, in the event that they do, going through the ground of Texas’ lineup turns out like a great time to smash it out.

X-factor No. 2: Who pitches to Alvarez overdue?

Realistically, the Astros’ lineup is just too just right to obsess over plans for a unmarried batter. Yordan Alvarez certain made a case for tough the highlight throughout Houston’s ALDS victory towards the Minnesota Twins. In 4 video games, he went 7 for 16 with two doubles and 4 house runs. He drove in six runs.

It’s on supervisor Bruce Bochy to in finding some more or less answer to Alvarez within the overdue innings. To that, we are saying: just right success. Take a take a look at Alvarez’s OPS the final 3 seasons towards each and every pitch sort, cut up by way of pitcher handedness:

For those that were not protecting rely, Alvarez has an OPS under .800 on precisely two varieties of pitch varieties: left-handed two-seamers and right-handed curveballs. Ignoring for a 2nd that Alvarez’s efficiency towards the ones specific pitches might range in line with speed, motion, and unlock level profiles — let’s accept it, no person studying this desires us to get that nerdy — listed below are relievers from the Rangers’ ALDS roster who have compatibility the ones parameters (wherein we imply they threw a minimum of 15% of that pitch sort in-season):

Chapman and Sborz had been positive to see high-leverage paintings on this collection anyway. In that sense, it really works out well for the Rangers. We will observe that final postseason equipped a just right reminder that even the “smart” play towards Alvarez can result in failure: 

In different phrases, tread moderately. 

NLCS: Phillies vs. Diamondbacks

X-factor No. 1: Heaters

We discussed above that X-factors steadily fall into considered one of 3 classes. Here, we are specializing in a perceived energy as opposed to a perceived weak spot. During the common season, the Phillies threw the 5th maximum fastballs and sinkers; the Diamondbacks, accordingly, ranked sixteenth in manufacturing as opposed to fastballs and sinkers — that is the third-worst mark amongst playoff groups.

Bear in thoughts that we are portray widely right here. Some hitters are higher at getting on most sensible of emerging four-seamers, simply as some are extra professional at lifting sinkers. What theoretically makes the Phillies a tricky matchup on this admire is that they are one of the most groups that got here closest to a 1:1 percentage of four-seamers and two-seamers throughout the common seasons (28.3% as opposed to 22.5%).

Here’s a take a look at the D-backs who carried out worse towards the ones distinct fastballs:

We’ll observe that one of the crucial D-backs’ worst offenders on this admire are not likely to component into the NLCS. Josh Rojas used to be traded on the time limit; Nick Ahmed used to be waived close to the top of the season; Jake McCarthy is injured; and spare infielders Jace Peterson, Jordan Lawlar, and Emmanuel Rivera gained a complete of 1 at-bat throughout the NLDS and 0 throughout the Wild Card Series.

As such, this won’t finally end up being as giant of an element as it seems that to start with blush. The Diamondbacks nonetheless might face a transparent downside each time the Phillies pump warmers in towards Alek Thomas and Geraldo Perdomo. 

X-factor No. 2: The working recreation

It’s no secret: those groups like to run. The Diamondbacks completed 2nd within the majors throughout the common season with 166 stolen bases. The Phillies ranked 7th with 141. Both groups saved up their thieving tactics within the playoffs. In the DS spherical, the Phillies went seven for 8 in 4 video games as opposed to the Braves, and the Diamondbacks went 5 for six in 3 video games towards the Dodgers.

While pitchers, no longer catchers, are most often those accountable for shutting down the working recreation, we really feel obligated to observe that each backstops had been higher at throwing out potential thieves than Statcast’s fashion projected throughout the common season. 

Indeed, Arizona’s Gabriel Moreno in truth led the majors with 9 stuck stealings above above. Philadelphia’s J.T. Realmuto, conversely, threw out two extra runners than anticipated. Here’s a look at some of their advanced metrics:

Will both be sufficient to stay Corbin Carroll, Trea Turner, or Bryson Stott tethered to first base? Almost in no way. But the standard of each catchers will make the ones stolen-base alternatives all of the extra thrilling to watch.
