We don’t talk much about Matt Holliday these days. It’s been awhile since he was one of the best players in baseball. Probably the last time you could have honestly made that claim was in 2014, when his 132 wRC+ was 28th-best in the game. However, with the news that Holliday has probably succumbed to his thumb injury for the rest of the season, I thought we would take a minute to talk about Holliday. Holliday can’t do most of the things he used to, but even after all this time can still hit.

Holliday has always had a special place in my heart because he got to Coors Field at the same time as I did. I started working for the Rockies in March of 2004, about a month before Holliday would make an unexpected major-league debut. He got the call when both Preston Wilson and Larry Walker came up lame in the first couple weeks of what would become (at the time) the bleakest moment in Rockies history. Technically, the team’s winning percentage had been worse in 1993, but in 1993 no one in the Rocky Mountain region had cared, because they had a major-league team for the first time.

That 2004 season was bad not just because of the team on the field, but because it was the year the team traded Larry Walker away — twice — getting far less in return the second time. The first time, when they tried to trade him to the Texas Rangers for Ian Kinsler, Walker had vetoed the deal. He was then sent to the Cardinals, which, in retrospect, was absolutely the right move for Walker, who would finally get to play in the World Series that fall. I’m pretty sure the Rockies would have rather had Kinsler than Chris Narveson, though. In any case, trading away Walker meant that any scant hopes the team would contend had totally and completely died. The “Todd (Helton) and the Toddlers” era had begun.

The most prominent “toddler” was Holliday. He would come along slowly, but he could always hit. As fate would have it, the season he put it all together coincided with Troy Tulowitzki‘s arrival and Todd Helton’s final good season, and the three helped lead the Rockies to their first and still only World Series berth. Holliday slugged .607 that season, and if that seems like a ridiculous number, it is. Coors Field might still be a hitting haven, but no Rockies player has slugged .600 since.

On August 19th, the Mets lost 8-1 to the Giants, dropping to 60-62 on the season. The loss, coupled with a depleted roster — that was just about to get more depleted, as they would place Steven Matz back on the disabled list three days later — pushed their playoff odds to a season-low 6.6%. Here’s what has happened over the last month, in graph form.

That is simply a remarkable image; the visualization of a team saving a nearly-lost season in very short order. Since that loss to the Giants, the Mets have gone 20-7, and have now taken the lead for the top spot in the NL Wild Card race. The defending NL Champs are now very likely to be back in the postseason, 30 days after they were just about to write their own eulogy. Let’s take a look at how they got here.

I don’t mean to stress out anybody whose teams are still fighting for a playoff spot, but the postseason is almost here. In less than two weeks fans of either the Mets, Giants, or Cardinals will be crushed as will fans of the majority of the (approximately) 82 teams vying for an American League Wild Card spot. When that time comes, the disappointed will be able to dry their tears while engaging in one of the great annual postseason traditions: overanalysis. For six months, we’ve been watching up to 15 games every night — a pace which lends itself nicely to broad, big-picture analysis more than football-esque gameday breakdowns. In the playoffs, however, that all changes and suddenly every game and series will be diced up and analyzed in every possible way, for better or worse.

One of the biggest ways this overanalysis creeps into our baseball consciousness is through an obsession over starting pitching. If you check a newspaper — I see you and I respect you, old-school newspaper folks — or open a game preview on the MLB.com At Bat app, the first thing you’ll find is that day’s starting-pitcher matchup. Is your team going to win on a given day? Better know who’s toeing the rubber to set your expectations correctly. Intellectually, we know that baseball is too unpredictable and complex to be effectively parsed down to a look at the day’s starters, but that won’t stop us. With that in mind, it’s been a rough stretch for a few playoff-bound teams who figure to see their starting rotations scrutinized under a high-power microscope over the next few weeks. I’m talking, of course, about Cleveland losing Carlos Carrasco and Danny Salazar to injury, the Mets losing Jacob deGrom, and the Nationals losing Stephen Strasburg.

The good news for each of those teams is that they all have at least one healthy ace-level pitcher remaining, but will that be enough when matching up against other ace-laden playoff rotations? Are any of them particularly well-suited to handle the loss? In preparation for overanalysis season, let’s take stock of what each of these injuries means to these teams and what their October rotations look like as things stand today.

Over the last calendar year, Andrew Miller has a 1.81 ERA and a 2.22 FIP. Those dominant numbers, combined with the compelling nature of Miller’s complete transformation, have rightfully earned him the reputation as perhaps baseball’s best active relief pitcher.

Over the last calendar year, Addison Reed has a 1.87 ERA and a 2.14 FIP. You might not have heard about it, but dating back 365 days, Reed’s been every bit as dominant as the guy who’s rightfully earned the reputation as perhaps baseball’s best active relief pitcher. And you might not have realized it, but Reed’s undergone a similarly compelling transformation that’s left him looking more and more like Miller than one might expect.

Porcello (201.2 IP, 91 xFIP-) vs. Bundy (99.2 IP, 108 xFIP-)
The AL East has been — and will remain for most of today, at least — the most tightly contested division in the majors. Here one finds two of the three principal characters in that race, Boston and Baltimore. In conclusion, this has been a brief, nearly unnecessary paragraph.

It’s been over a year now since Sean Dolinar and I published our article(s) on reliability and uncertainty in baseball stats. When we wrote that, we had the intention of running reliability numbers for even more statistics, including pitching statistics, of which we had included none.

That didn’t happen. So a little while ago, when I was practicing honing my Python skills by rewriting our code in, well, Python (it was originally in R), I figured, “Hey, why not go back and do this for a bunch more stats?” That did happen. Sean was/is swamped making the site infinitely better, though, so I was on my own rewriting the code.

In case you need a refresher, never read our original article, and/or don’t want to now, here’s a quick description of reliability and uncertainty: reliability is a coefficient between 0 and 1 that gives a sense of the consistency of a statistic. A higher reliability means that there’s less uncertainty in the measurement. Reliability will go up with a larger sample size, so the reliability for strikeout rate after 100 plate appearances is going to be much lower than the reliability for strikeout rate at 600. Reliability also changes depending on which stat is being measured. Since strikeout rate is obviously a more talent-based stat than hit-by-pitch rate (well, maybe not for everybody), the reliability is going to be higher for strikeouts given two identical samples. You can think of it like strikeouts “stabilize” quicker than hit-by-pitches.

Reliability can be used to regress a player’s stats to the mean and then to create error bars around that, giving a confidence interval of the player’s true talent. To continue with the strikeout example, I’ll add another point — namely that, the more plate appearances a player has recorded, the closer the estimate of his true talent will be to the strikeout rate he’s running at the time. In fact, strikeout rate is so reliable that, after a full season’s worth of plate appearances, a player’s strikeout rate will probably be almost exactly reflective of his true talent. The same cannot be said for many other stats, like line drive rate, which is mostly random; the reliability for LD% never gets very high, even after a full season’s worth of batted balls.

St. Louis at San Francisco | 16:05 ET
Reyes (28.0 IP, 95 xFIP-) vs. Suarez (75.0 IP, 109 xFIP-)
St. Louis’s wild-card odds have declined by nearly 20 points since Thursday, an interval which accounts for the first three games of their series against San Francisco in the latter’s ballpark. The results could have been worse: had they not won last night, the loss in wild-card probability would likely have amounted to roughly 30 points.

Regard:

The endeavor has become more difficult in the meantime, as well, with the recent success of the Mets — rendering a win today even more consequential.

Rob Refsnyder has gone deep just 37 times since the Yankees drafted him out of the University of Arizona in 2012. He’s homered twice this year in 397 plate appearances between Triple-A and the big leagues. Power hasn’t been a forte.

He wants that to change.

“I’m going to try to hit home runs next year,” Refsnyder told me on Friday. “I’ve had a lot of good conversations with people and I’m going to try to completely change my game. I think it will help my career.”

The change may be necessary. Refsnyder has good bat-to-ball skills, but he’s neither a speed-burner nor a plus defender. He came up through the Yankees system as a second baseman, but with Starlin Castro manning that position, he’s been seeing action at first base and in right field. Without added pop, he’s unlikely to be an everyday player going forward.

He has role models for his goal. Read the rest of this entry »
