The first of two Wild Card games is scheduled for tonight. In addition to must-win baseball, this time of year is also typically marked by the appearance of a Dave Cameron piece on the merits of “bullpen-ing” a game — that is, the practice of using nothing but relievers in a single contest, of attempting to exploit matchups in order to maximize the chances of winning.

While the logic of “bullpen-ing” is sound in theory, it also fails to account for the comfort of pitchers who’ve potentially become attached to their roles. To get a better idea of how they might adapt to such an approach and how it might be handled in practice, I asked some actual players about it. Turns out, there’s a particular type of reliever who’s best suited to take the ball in the first few innings of a win-or-go-home game. And a particular type of pitcher who should follow him.

The first thing revealed by my inquiries is that relievers love the idea. “I’m down for whatever,” said Giants reliever Hunter Strickland with a smile. Nationals closer Sean Doolittle just laughed for a while. “Would I get paid like a starting pitcher?” he finally asked after the laughter had subsided.

Relievers would be fine with it because they’re accustomed to answering the call whenever. “We’re used to throwing in whatever inning, [if] not usually the first,” said Strickland. Added Miami’s Brad Ziegler: “I don’t think it would be very different for me, as much as it would be for the starter coming into the game [in the later innings]. His whole routine would have to change.”

And a starter probably would have to throw a couple innings in such a game — in order to reach a full complement of nine and still leave some arms for extras, that is. So the question is probably which kind of starter would adapt effectively to an otherwise unusual arrangement.

The answer? Probably a young one. Older starters are more married to their routines. “It’s very hard for me personally,” said Brandon McCarthy regarding the idea of starting a game in any other inning but the first. “My routine as a starter is fixed to the minute and a lot of guys are like that. It’s certainly not something impossible to deal with but could make a team nervous.”

This time of year excites me for two reasons. One, of course, we’ve got the playoffs coming up, and no matter what you think about how the tournament is designed, this month is as exciting as baseball can get. Today and tomorrow, teams will be eliminated! Everything ends, ever so suddenly! It’s a gas. The other thing I love, though, is that all the season statistics are final. For the first time, I get to stop worrying about projections or extrapolations. What happened has happened. There is no more of the regular season, so the numbers on the leaderboards are as they will be forever.

It makes the writing easier, and more matter-of-fact. For example, here is a matter of certain fact: The 2017 Houston Astros had baseball’s most improved lineup. How can I say that? No one else improved by nearly so much in wRC+.

This season, 144 players reached the 502-plate-appearance threshold necessary to qualify for the batting title. On the opposite end of the spectrum, there were 190 position players who tallied between one and 99 PA for the season. In between, there were 291 position players. Some of these were starters who simply missed time due to injury (Bryce Harper, for example) or the nature of their position (Salvador Perez) or because they weren’t major leaguers yet at the start of the season (Paul DeJong), but some of them are what we’d call true part-time players. At this time of year, we generally focus on the very best players. It’s awards season, after all. Part-time players get less shine. So let’s focus on them today, at the very least.

I’ve done this exercise once before, back in 2012. Now, as then, I’ve parsed the list to give us a clear picture of who is really a part-time player. My favorite tool for this exercise is the “Lineups and Defense” pages on Baseball-Reference. When they redesigned the website recently (I think it was recently? Maybe it was last year? I don’t know, I don’t even remember what I had for dinner on Thursday.) I experienced a few panicky minutes when I couldn’t find the pages, but fortunately they’re still there. Phew.

Charlie Morton had a career year. In his first season with the Houston Astros, the 33-year-old right-hander is heading into October baseball with a record of 14-7 and a 3.62 ERA. The win total is a personal best, as are his 3.46 FIP and his 7.7 H/9.

Especially notable are his 10 strikeouts per nine innings and his 51.8% ground ball rate. The former is by far his highest, and the latter is by far his lowest. Morton was not only good during the regular season, he was also not the same pitcher he was in Pittsburgh.

“My stuff is different this year,” Morton told me on Thursday. “It’s not sinking as much — it’s harder, but it’s not sinking as much. My curve isn’t as vertical as it usually is; it’s not moving as much.

“When I was with the Pirates, from 2009-2015, I was a heavy sinker guy. I was over 60%, sinkers, and this year, against lefties, I might throw five sinkers in the whole game. My two-seam control has suffered a little bit, because I’m not throwing it as much. I’m four-seam, curveball, cutter, changeup — more of a mix. So really… it’s a balance of your identity, and of what you’re trying to do.” Read the rest of this entry »

Quick: who’s the best left-handed hitter likely to appear in the American League playoffs this October? If you took more than three seconds to come up with an answer, don’t worry, that’s perfectly normal. The National League contenders have plenty of high-profile left-handed hitters: Charlie Blackmon, Cody Bellinger, Bryce Harper, Daniel Murphy, and Anthony Rizzo immediately stand out. Not so in the American League.

Postseason roster construction can have a lot of consequences. Once rosters are set, there are only so many machinations that can or will surprise us, but in a lot of cases, series can be won or lost by the selection of the the last five guys on the roster. I focused on some interesting roster-construction decisions last week. In the meantime, the possible configurations of the Astros bullpen have remained with me. If Houston utilizes a tandem-starter approach, it will lessen their flexibility for their bullpen; as such, they might not have room for LOOGYs. Of course, a LOOGY is only necessary to the extent that there are dangerous left-handed batters to face. The potential absence of a LOOGY from the Houston bullpen led me to a larger question about the batters whom that pitcher might face — specifically, whether any of the AL teams need a LOOGY to navigate October?

George Springer is hitting for contact.

Much has been written about how, this year, the Astros have easily the lowest strikeout rate in baseball. One of the most strikeout-heavy lineups around has opted to put the bat on the ball, and now the Astros have a giant lead in wRC+. Part of that improvement in contact comes from adding players like Josh Reddick and Brian McCann. Part of that improvement in contact comes from the emergence of Yulieski Gurriel. And part of that improvement in contact comes from George Springer’s improvement in contact.

Young players improve. When you start to learn the major leagues, you tend to get better. But this — this is extraordinary. This isn’t just a young Astros player doing better at baseball. This is *George Springer,* making contact on a consistent basis, and if that doesn’t immediately grab your attention, perhaps it’s because you’ve forgotten what Springer used to be.

With still roughly two weeks left in the regular season, the divisional races across the major leagues have sputtered and nearly died. Three divisions have already been clinched. The Los Angeles Dodgers have already guaranteed themselves a playoff berth and should secure the National League West in short order. Beyond the Wild Card races, then, the NL Central and AL East remain the only hope for meaningful baseball over the season’s closing weeks. The Cubs have a four-game lead in the former and 96.6% odds of taking the division. The Red Sox, meanwhile, possess a three-game lead in the latter and 89.6% odds.

The Cubs have four games this week with the Brewers in Milwaukee. That series has a chance to facilitate some of the season’s most consequential games, provided Milwaukee can remain within striking distance of Chicago in the meantime. As for the Red Sox, though, don’t play the second-place Yankees again, which will make it tougher for the latter club to make up ground.

The bright side of having these races more or less decided is that we can start to look at the potential rosters for the League Division Series a little sooner. I’ll begin today with the American League. For the purposes of this exercise, I’ll proceed by the odds and regard the Red Sox as the presumptive winners of the East. If that turns out not to be the case, feel free to come back here in October and squawk at me.

Even just a couple months ago, Justin Verlander was a name. He was a name with a contract and diminished results, and his desirability on the market was low. Teams were interested in him, for sure — teams would always be interested in someone with Verlander’s background. Yet his performance wasn’t matching up with his cost, and so it didn’t seem like a trade would be likely. The Tigers didn’t want to give their legend away, yet contenders didn’t want to pay for someone whose best days were long gone.

Ultimately, Verlander did get traded. The Tigers, admittedly, paid him down, but the Astros picked up the bulk of the money, and they even gave up three legitimate prospects. The Astros paid for Verlander as if Verlander were an ace again. And for the past several weeks, Verlander has resembled an ace. He made his debut for Houston on Tuesday, and he allowed one run over six innings. Verlander’s gotten back to looking like one of the best in the world. So, what changed? What convinced the Astros to pay what they did? Outside of their own pitching issues, I mean. Verlander, it won’t surprise you, has made a couple tweaks.

Detroit acquired a trio of prospects from Houston last night in exchange for Justin Verlander. Two of those prospects appeared on our updated Astros top-10 list and will likely occupy a similar place in Detroit’s improving system. Before we examine the state of the Tigers’ minor-league talent, however, let’s talk about the three young men who were just traded for one of this century’s best right-handed pitchers.

The centerpiece of this package is 19-year-old Venezuelan righty Franklin Perez. Perez began the year with three dominant starts in High-A before he was shelved for a month with knee soreness. His results have been mixed but generally positive since his late-May return. Despite a few hiccups, Perez was promoted to Double-A in July and has struggled with strike-throwing at times while missing fewer bats than he did in A-ball. But ultimately, we’re talking about a 19-year-old who, despite initially training in Venezuela as a third baseman, has already pitched his way to Double-A and who, when healthy and rested, shows an ability to locate and sequence four quality big-league offerings.

A month ago, when the dust settled on the July 31st trade deadline, the Astros had added just left-hander Francisco Liriano, whose struggles were one of the main reasons the Blue Jays failed to contend in 2017. It was an underwhelming upgrade for a team headed for the postseason, and the fact that the team thought they had a deal for Zach Britton was little solace to disappointed fans and players who hoped for more reinforcements.

Well, it took a month, but reinforcements are here, and this particular reinforcement throws really hard.
