Most Highly Rated Game
Kansas City at Detroit | 19:10 ET
Duffy (169.2 IP, 87 xFIP-) vs. Fulmer (148.2 IP, 94 xFIP-)
For as bananas as the National League’s wild-card picture has become — featuring three clubs in a sometimes virtual, sometimes actual real tie — the American League’s version has become roughly that same number of bananas. As of this morning, five clubs continue to possess at least a 10% probability of qualifying for a berth according to this site’s methodology:

Second-place Detroit has never possessed playoff odds much above 60% this year. A victory tonight would likely allow them to cross that particular threshold. Helping them in that endeavor is young right-hander Michael Fulmer, who either should win the Rookie of the Year or shouldn’t per Jeff Sullivan.

Atlanta Braves fans are waiting for their team to be consistently good again. After winning the division handily in 2013 but losing in the NLDS, the team fired general manager Frank Wren at the end of the following year. They replaced him with a duo: president of baseball pperations John Hart and GM John Coppolella. These two combined with longtime Braves executive John Schuerholz to form the team’s new brain trust.

They began rebuilding immediately. That offseason they sent familiar faces Evan Gattis, Jason Heyward, Craig Kimbrel, Justin Upton and Melvin Upton Jr. all packing. They signed longtime Oriole Nick Markakis. Midway through 2015, the team traded Alex Wood. After the season, they dealt Andrelton Simmons and then Shelby Miller. The only notable names remaining from Wren’s time were Freddie Freeman and Julio Teheran.

Two years after the regime change, I wanted to evaluate their efforts. But first, I needed metrics. How does one evaluate a rebuild? After pondering the subject, I landed on three aspects: team run differential, time, and payroll flexibility. Below I discuss how the Braves are doing in these areas.

I’ve been thinking a lot lately about the Rangers’ success in one-run games. They actually lost by one run yesterday, but if you’ve been paying attention, that was the first time that’s happened all season, probably, and one game doesn’t upset the whole pattern. The regular season is just about done, and the Rangers have put together an incredible stat. That’s — well, it’s incredible. I don’t need to provide any other words.

It’s tricky to write about these things, and I wasn’t looking to cover this in the familiar way. We’ve all read a number of articles about what the Rangers have done. We’ve all read articles before about similar teams doing similar things. It’s boring to say “luck,” and it’s tired to say “luck,” and with the playoffs around the corner pointing toward luck is additionally irrelevant. The Rangers have done what they’ve done, and their fans have been able to enjoy it. There’s no taking any of that enjoyment back for math-y purposes.

I’ve just been amazed by how the Rangers have stood out. They’ve won 77% of their one-run games. The Yankees are in second at 69%. Then you have the Tigers at 62%. Thinking about the Rangers got me wondering: Is this the most extraordinary team statistic of the year? I’ll tell you right now: It’s not! Follow along below.

Ben and Sam banter about the Giants’ bullpen problems and Bryce Harper’s shoulder, then answer listener emails about Terrance Gore, Gary Sanchez, calling time, playoff formats, one-pitch baseball, and more.

We’re headed down the regular-season home stretch, with nearly a full campaign’s worth of data in the books. In my next two posts, we’ll measure the contact-management performance of qualifying starting pitchers in both leagues. Today, let’s look at the National League.

Just in case you’ve missed it — Jose Abreu, earlier, was a massive disappointment. For as long as the White Sox were worth paying attention to this year, Abreu was underachieving. It was one of the critical things holding them back, as Abreu generated a first-half line that was a little worse than average. In the second half, as the White Sox have faded, Abreu’s been fantastic. That’s not to suggest there’s some sort of weird-ass inverse relationship between Abreu’s hitting and Chicago’s winning. Abreu has just found his footing again. He’s playing like an All-Star again. That should make the White Sox feel better as they turn their attention to the offseason ahead.

So, Abreu’s improved. The power is up, and he’s cut down on the whiffs. But, about some of those whiffs. It’s probably too late in the year for Abreu to pull off the full Strikeout Bingo. He’d have to really make an effort. Nevertheless, he’s gotten halfway there. It’s a notable accomplishment, if not one Abreu would want to talk about.

With the minor-league playoffs finished, the Baltimore Orioles summoned first-base prospect Trey Mancini from Triple-A Norfolk this week to help sure up their offense. Mancini wasted no time making an impact for the O’s, notching his first career home run in Tuesday’s game against the Red Sox. Mancini broke out in 2015 when he slashed an outstanding .331/.370/.539 between High-A and Double-A. His raw numbers regressed a bit this season as he moved to a more pitcher-friendly park, but he still managed a strong .282/.357/.458 showing, with almost all of that coming at Triple-A.

Mancini’s power is enticing. In each of the last two seasons, he’s reached the 20-homer mark and ISO’d over .175. However, some of his other attributes take away from some of that shine. Mancini’s a first baseman, meaning he’ll need to hit a bunch to have a long-term future in the bigs. He also turns 25 next spring, making him a bit old for even the Triple-A level. And perhaps most importantly, he kind of strikes out a lot — likely due in part to his long swing.

Following the end of their Triple-A affiliate’s championship season in the Pacific Coast League, the San Diego Padres promoted a small collection of players to their major-league club on Tuesday. Below are forecasts for the three most notable prospects of that group — Carlos Asuaje, Hunter Renfroe, and Manuel Margot — according to my KATOH system and presented in order of projected WAR.

Note that KATOH represents the WAR projection for the relevant player’s first six years in the majors; KATOH+ is that same thing, except with the player’s Baseball America ranking included as a variable.

Manny Margot, CF (Profile)

KATOH: 13.0 WAR
KATOH+: 13.6 WAR

Margot’s game centers around speed and contact. The 21-year-old struck out in just 12% of his plate appearances in Triple-A this year on his way to a .307/.355/.442 slash line. He also racked up an exciting 32 steals, while playing elite center field defense by Clay Davenport’s numbers. Margot also isn’t a zero in the power department, as he managed a respectable 46 extra-base hits in the minors this year, including seven homers. He’s one of the very best prospects in baseball by my math, and he’s big-league ready.

To help you visualize what his KATOH projection entails, here is a probability density function showing KATOH+’s projected distribution of outcomes for Margot’s first six seasons in the major leagues.

To put some faces to Margot’s statistical profile, let’s generate some statistical comps for the speedy outfielder. I calculated a weighted Mahalanobis distance between Margot’s performance this year and every Triple-A season since 1991 in which a center fielder recorded at least 400 plate appearances. In the table below, you’ll find the 10 most similar seasons, ranked from most to least similar. The WAR totals refer to each player’s first six seasons in the major leagues. A lower “Mah Dist” reading indicates a closer comp.

In October 2011, a Q&A titled Zach Britton, Oriole in Progress was published in these pages. Britton had just completed a rookie season in which he went 11-11, with a 4.61 ERA, in 28 starts. He’d thrown his signature pitch 53% of the time.

Fast forward to today. Britton is still in Baltimore, but much has changed. He became a reliever in 2014, and the results have been nothing short of spectacular. Since moving to the bullpen, the 28-year-old southpaw has appeared in 199 games and fashioned a 1.42 ERA. Relying more heavily on his power sinker — he now throws it over 90% of the time — he has the highest ground-ball rate in the game (80.8% this year). He also misses bats. Britton strikes out better than a batter per inning.

This season he’s been next to un-hittable. In 61.1 innings, Britton has allowed just 34 hits. He’s recorded a microscopic 0.59 ERA and has 45 saves in as many chances. As August Fagerstrom wrote last month — many have echoed his opinion since that time — Britton is very much in the mix for this year’s American League Cy Young award.

———

Britton on his pitch mix and changing roles: “There were a lot more four-seamers back [in 2011]. As a starter, you throw more pitches and mix in different things. It was probably a negative for me that I wasn’t learning how to command the sinker as much as I am now. That was really the big focus when I went to the bullpen — the command of my sinker. The results have been really good once I got that focus.
