Major League Baseball interrupts this Thanksgiving holiday week to announce that Jed Lowrie has been traded from the Astros to the A’s in exchange for minor-league reliever Brendan McCurry. Perhaps it’s a move you find a little strange — Lowrie is in his 30s, and he’s due real money for at least another couple years. He’s going from one team with a very low payroll to another, and last year, the team adding Lowrie won 18 fewer games than the team shedding Lowrie. Typically you see trades like this in the other direction, but for the Astros, Lowrie was no longer a necessary piece. And the A’s are forever on the bubble, trying to avoid any kind of major tear-down. The A’s want to try to contend again. Having Liam Hendriks and a hopefully healthy Sean Doolittle addresses what last year was a catastrophic problem.

That’s the whole idea, in short. The Astros didn’t need Lowrie, and they’ll take the financial flexibility and the interesting young reliever. McCurry could have a real future, and he could have it soon. The A’s, meanwhile, are happy to have Lowrie back at a modest cost, and they like his flexibility. From one perspective, he gives them depth; from another perspective, he gives them trade options. A healthier A’s team could be a .500 ballclub, and a .500 ballclub is always close to the hunt. Okay, everything checks out.

The thing I find most interesting isn’t the Astros’ position, nor is it the A’s position. It isn’t McCurry, either. It’s Lowrie himself. Just how good is Jed Lowrie, really? There’s room for very reasonable disagreement.

When you come up through the ranks as a young lefty starter, you learn about the importance of the changeup. By breaking away from the right-handed batter, that pitch offers the best way to neutralize the natural platoon advantage those hitters have against you. By the time you get to the big leagues, it’s part of your approach, like it or not. That’s why lefty starters throw changeups 65% more often than righty starters in major league baseball.

If you look at Jon Lester’s career, though, his best years have come when he’s thrown his changeup the least. The flippant reason for that truth might be because his changeup isn’t that great, and his other pitches are better. The long version is much more interesting, though, as it gets to the theory of changeups, and a new concept called tunneling.

When Dave Cameron wrote up the Athletics’ signing of Rich Hill yesterday, he titled it “A’s Sign Rich Hill, Because Of Course They Do.” He focused more on the fact that Hill was a resurgent pitcher that represented a low-risk, high-reward, low-money signing — a bit like Scott Kazmir before the 2014 season. That makes a lot of sense, given Oakland’s budget constraints and past practices.

There’s another way Hill is the perfect major league acquisition for the Athletics, though. He’s a fastball/curve guy with an iffy changeup. He’ll fit right in.

Earlier this week, I took a look at the AL Cy Young race, utilizing batted-ball metrics to address the respective candidacies of David Price, Dallas Keuchel and Chris Sale. To make a long story short, I concluded that Sale’s strikeout-to-walk (K/BB) superiority, along with solid contact management skills that have been obscured by his horrendous team defense, placed him on top. Some readers expressed incredulity in the comment section, not believing that even the worst defense in the game could cost a pitcher one full point of ERA.

Today, let’s look at the counterweight to Chris Sale, Sonny Gray. Though he wasn’t quite the same guy in the second half as he was in the first, he has wrapped up a very strong campaign, especially in the more traditionally accepted statistical categories. He’ll finish third in the AL in ERA (2.73) and is likely to receive his share of down-ballot Cy Young votes, possibly enough to nose out Sale for third place overall. Sale’s ERA is 0.78 higher than his FIP, and as we saw the other day, 1.02 higher than his “tru” ERA, which incorporates Statcast batted ball data. Gray finishes 2015 with an ERA 0.73 lower than his FIP. What gives, and what is the true talent level exhibited by Gray this season?

Sam Fuld was checking out his FanGraphs page the other day, and noticed that he’s a fairly fast-paced guy at the plate. He produced in 2011 the 36th-fastest pace between that season and the present one (minimum 300 plate appearances), and he’s the 20th-fastest paced batter this year. He also noticed something about the guys around him. “They’re all slap hitters!” he told me before a game against the Rangers.

He wondered if pace was correlated to power, and if this slower pace came through the mechanism of confidence. “I’m the star here,” he said, mimicking a step back out of the box and a shrug of the shoulders that’s a little foreign to the Athletics outfielder with 12 career home runs spread over nine years and 1500-plus plate appearances.

Barry Zito is coming back! Zito, who hasn’t thrown a pitch in the majors since 2013, has been called up from Triple-A by the A’s. He’ll initially work out of the bullpen — which makes sense because what bullpen doesn’t need an old guy with no command who throws really slow? — but the A’s are so out of playoff contention they may as well clone an entire Zito army and deploy it in relief. “Looks like Clone Zito doesn’t have it tonight, and here’s Bob Melvin to make a change. He’s signaling for the left-hander, and here comes Clone Zito trolling in from the pen. This pitching change is sponsored by Firestone tires, by Zippo lighters, and by Shell Gasoline.”

I mention that so I can mention this: I wonder if Barry Zito can throw the slowest fastball this season? Zito is renowned for his fastball velocity like Metallica is renowned for their depth and subtlety. Back in 2007, Zito’s fastball reached 93 mph, but over the years he lost velocity like a ship made of chicken wire loses buoyancy. In his most recent season, 2013, his four-seamer averaged 82.6 mph with a high of 85.6 mph and a low of…

While working on something Erasmo Ramirez said — that his slider was always in the zone anyway, so he should probably use it to steal strikes rather than for swinging strikes — it became obvious that breaking pitches are much less effective in the zone than out when it comes to swinging strikes. Curves, in particular, are much better outside the zone. You get about one third of the whiffs on a curve in the zone as you do outside of the zone.

Separately, I’m working on a piece for The Hardball Times Annual about command. In it, a few pitchers talk about the difficulty of commanding breaking pitches. “Nobody throws anything that’s truly straight,” is how Trevor Bauer put it.

While sorting the in and out of zone whiff rates, and thinking about command, it came to me that the two are related. Maybe that’s a duh, but a big part of quantifying command is the problem of breaking balls and changeups and their movement. A breaking ball in the zone may often be a hung breaking ball, which contributes to the lower whiff rates.

Let’s take a look at the pitchers that have the most disparate results on their non fastballs inside and outside the zone first, and then try to find a way to spot these pitchers by movement.

The first time Sean Doolittle’s career almost ended, he still owned a first baseman’s glove. The second time his career almost ended, he was clutching his throwing shoulder and wondering why he couldn’t crack 90 mph on the radar gun. During his second comeback, often he wondered why he was “pitching with the brake on” as he put it last week.

A tweak to his repertoire and a tweak to his rehab, and things are starting to look up for the Oakland left-hander. He’s now hit 95 mph six times in his last three outings, including Monday in the second half of a back-to-back appearance.

Two seasons ago, I ranked the job security of each general manager and listed GM prospects. I think I did a pretty good job with both lists given what we knew at the time, and may do it again as Opening Day 2016 closes in. We’ve had less executive movement in the last few off-seasons than usual and it looks like the regression is happening this year, with four GM jobs currently open and a likely fifth coming soon. This seemed like a good time to cover each of the situations in flux and target some possible changes in the near future, along with some names to keep in mind as candidates to fill these openings.

The Open GM Spots
We have two teams without a top baseball decision-making executive, in Seattle and Milwaukee:

Mariners
The Mariners moved on from (now former) GM Jack Zduriencik recently, a long-rumored move that club president Kevin Mather admitted he waited too long to execute. Mather has said they’re looking for a replacement sooner than later (likely eliminating execs from playoff teams), with GM experience (eliminating most of the GM prospects you’ll see below), and that the team doesn’t require a rebuild (meaning a shorter leash and higher expectations from day one). This should prove to narrow the pool of candidates a good bit, but this is still seen as the best of the currently open jobs.

In a slump, the mental and physical combine to confuse, and the player ends up in a spiral. “You go up to the plate and you think about your weaknesses, and you start focusing on them, and you start chasing,” Brandon Moss said before a game against the Giants, adding “it all starts to spin around.” Since having offseason hip surgery, the Cardinals’ slugger has been spinning in both facets of the game.

A recent tear might be the result of getting right, though. An adjustment to his mechanics, a milestone in his workouts, and a slight tweak to his approach all recently came together. The result looks more like the Moss that averaged 33 home runs for every 600 plate appearances coming into this season.

To illustrate how he’s gotten his game back together, there might not be a better way than to have Moss take us through three plate appearances against Rubby de la Rosa last week. The pitcher got the better of him once, but when the batter did his damage, it was the result of a convergence of factors.
