The Mariners started James Paxton on Wednesday because they had to put Felix Hernandez on the disabled list with a hurt leg. That’s bad! Paxton proceeded to get lit up, by literally the San Diego Padres. That’s worse! Here, watch Paxton give up an opposite-field dinger to Wil Myers:

Familiar enough. Here’s last year’s Paxton giving up a dinger to Eduardo Escobar:

There’s nothing good about giving up eight runs in less than four innings. It’s even worse when that happens in a pitcher-friendly environment, against a pitcher-friendly opponent. Paxton was so ineffective the Mariners won’t commit to giving him another go, even though Felix is down a few weeks. By results, Wednesday was a nightmare.

By process? By process, it was less nightmarish. There were actually positive signs. Based on everything but the results, Paxton showed promising skills, and the Mariners should want for him to get another opportunity.

I keep a little notebook next to my computer, so I can keep track of potential things to write about. Generally, topics break down into two categories: there are the topics that practically need to be written about, and there are the possible topics to monitor. Maybe those need bigger sample sizes; maybe those just need to become more interesting. Some of those topics turn into posts, and some of those topics never leave the piece of paper. I see that I crossed out something about Joe Ross. No idea what that was supposed to be.

For weeks, because of the notebook, I’ve been casually following Leonys Martin. I noticed in the early going that Martin didn’t look like himself: he was striking out a bunch, but he was also hitting more baseballs in the air. That seemed to me like something to follow, and wouldn’t you know it, but here we are, and Martin is still a fly-ball hitter. That’s odd because, in his entire major-league past, Martin was a ground-ball hitter. We’re more than a quarter of the way through the season, and now Leonys Martin appears to be a bat worth talking about.

This isn’t my own subjective interpretation. When you throw around a word like “favorites,” that opens the door to opinion-based writing, but I have numbers on my side. Sweet, sweet, precious numbers. Look at the following table. You have our preseason projected win totals, and our current projected win totals, which take into account everything that’s happened.

We liked the Astros a lot. Still do, but they’ve done themselves considerable harm. After the Astros, there was a group of four teams, all vying for second or last. The Mariners have emerged through the early going, and now they’re well out in front. Sure, that’s just us, but if it makes you feel any more trusting, PECOTA agrees. Projections still like the Astros, but the Astros are way behind the Mariners, just because of the games in the books. So the Mariners find themselves in a great divisional position. Getting to the point faster: This.

A lot has gone into that picture. Let’s talk.

When you’ve got a problem with command, your options seem obvious. You can clean up your mechanics, which is easier said then done. You can focus on throwing strike one. You can move on the rubber in order to move your heat map to a better spot. You can tinker with your fastball selection in case you have better command or outcomes with one of them. You can limit throwing a secondary pitch you don’t command that well. You can throw in the zone more and risk home runs if you miss more middle-middle.

It looks like Seattle’s Taijuan Walker is fighting poor command with a new weapon: throwing a secondary pitch in the zone more often. The best part is that, if it’s the right secondary pitch, command of that pitch is not super important. Tai’s fighting with a new approach to his curveball.

I recognize that this is a sensitive subject at a lousy time. I mean, the Mariners are winning, winning on a fairly sustained basis, and Felix Hernandez owns a lower ERA than Stephen Strasburg and Noah Syndergaard. According to our playoff odds page, the Mariners have a better than 50% chance of getting to the postseason, which for Felix would be his first-ever taste of those stakes. Mariners fans aren’t looking to be worried. Not now, not when they have circumstances to appreciate.

So I know this post might be interpreted as a bit of a bummer. It’s not meant that way; these are just observations. And no part of me presently thinks that Felix is toast. It’s just, there are things to talk about. What Felix has been doing, he’s never before done quite like this. It’s looking like he could be beginning a new chapter.

You’ve read articles like this before. That’s because Taijuan Walker has been a somebody for years, and we’ve all been waiting for him to kick it up. When you know a player is already hyped, you’re predisposed to think the most of any encouraging performances. It’s a bias, is what it is, leading observers to get ahead of themselves. I think, in the past, it’s been easy to get too excited about Walker. He needed to show more. But that’s why this is a post now. He’s showing more. Taijuan Walker is showing signs that he might be almost complete.

You remember that something seemed to click for Walker toward the end of last May. Through nine starts, he had 23 walks and 39 strikeouts. Through the remaining 20 starts, he had 17 walks and 118 strikeouts. That got people excited, and rightfully so, because those are tremendous indicators of improvement. But something was missing. Something was just a little bit off — over those 20 starts, Walker ran a near-average ERA. He had the strikes, and he had the whiffs, but he didn’t have the contact management. He was tantalizing, but unfinished.

I’m not declaring that Walker now is finished. That’ll take more proof. But Walker, this year, has carried over the walks and the strikeouts. In that sense, he looks exactly the same. Yet he’s allowed just one home run. He’s giving up far less solid contact, having dramatically increased his rate of grounders. Coming in, Walker was missing one thing. It seems he could be finding it.

Maybe it was the fact that she spent her formative years in Germany, while I spent most of mine in Jamaica and America’s South, but my mother and I have always disagreed about a fundamental thing when it comes to the weather. For her, she wants the sun. It doesn’t matter if it’s bitter cold and dry; if the sun’s out, she’s fine. I’d rather it was warm. Don’t care if there’s a drizzle or humidity or whatever.

It turns out, when we were disagreeing about these things, we were really talking about pitching. Mostly because life is pitching and pitching is life.

But also because the temperature, and the temperature alone, does not tell the story of pitching in the cold. It’ll make sense, just stick with it.

Baseball can be slow to change. We’ve had this idea for decades that certain pitch types have platoon splits, and that you should avoid them in certain situations because of it. Righties, don’t throw sliders to lefties! It’s Baseball 101.

Think of the changeup, too. “Does he have a changeup?” or some variation on the theme is the first question uttered of any prospect on the way up. It’s shorthand for “can he be a starter?” because we think of changeups as weapons against the opposite hand. A righty will need one to get lefties out and turn the lineup over, back to the other righties, who will be dispatched using breaking balls.

As with all conventional wisdom, this notion of handedness and pitch types should be rife for manipulation. Say you could use your changeup effectively against same-handed hitters, for example. You could have a fastball/changeup starter that was equally effective against both hands, despite the history of platoon splits on the pitch.

To the innovators go the spoils. And we’re starting to see some innovators.

Did you, like many others, come into this season wondering what to expect out of Robinson Cano? Did you believe that reports of his demise might be greatly exaggerated? Well, if three games are any indication, wonder no longer. He’s hit four home runs in 14 plate appearances! I don’t really need to dive too deep into his wRC+ (it’s 340), or many other stats at this point in the season, because they’ll simply reinforce for you that he’s been pretty impossibly good in 27 innings of baseball. The “I don’t need to hit the ball in the field of play” second baseman has a BABIP of .000. The point of this piece, then, is to tell you how and why Cano has been good, and the specific parts of his plate approach that are assuaging some of the fears people had about him last season.

Cano’s 2015 featured, at root, two halves. Every season of every player’s career features two halves, but Cano’s were relevant in that his production was starkly divided between the two of them. There was pre-July 1st Cano, he of the .105 ISO and 71 wRC+. And then there was post-July 1st Cano, he of the .209 ISO and 157 wRC+. Second-half Cano was literally 100% better than first-half Cano when compared to league average.

If you’re reading this, you probably know that everyone was trying to figure out what was wrong in that first half. Here’s Jeff mainly talking about him hitting too many ground balls. Here’s Dan going in-depth on how his hitting mechanics were a little messed-up. Here’s an interview in which Cano says a stomach parasite sapped his strength. There was obviously a lot going on, and his first-half performance was probably all of those negative forces coming together in the form of terrible baseballing.

The second half of 2015 was a complete turnaround, however. He started to hit more line drives and fly balls. He went to the opposite field at something closer to his career rates. His home run/fly ball rate and BABIP regressed toward (and surpassed) his career norms. His first half probably wasn’t as bad as it looked, but his second half was a pretty effective inversion of that. Players in their early 30s who play poorly for extended periods while on massive contracts tend to be placed under a microscope, however, so questions about Cano’s partial 2015 failures followed him into 2016.

He’s answered those questions pretty effectively in the early going. And, while we shouldn’t take anything away from what Cano’s done so far, we also need to ask some questions of how the Rangers approached him in their just-concluded opening series. Sure, we should remind ourselves that it’s just three games, but the very obvious way Texas pitched to him could act as a bit of a warning for those teams about to face him. So how did the Rangers approach him? The answer was, unequivocally, “witin the zone.” Take a look at Cano’s in-zone rate and rate of first-pitch strikes from 2013 to 2015 as compared to the series against the Rangers:

Let’s talk about the King. Felix Hernandez lost his start on opening day. In one sense, it was just the same old Mariners — Felix allowed one earned run, and literally just one hit, a fly-ball blooper into the shallow outfield. So, that makes it sound crazy, but Felix also walked five batters in six innings, and put a sixth on base by hitting him. Fewer than 60% of his pitches were strikes, which would be a bad mark for anyone, and Felix acknowledged he wasn’t working like himself. The plus side, naturally, is that he still wasn’t hittable. But he was kind of wild, and — and — his velocity was down.

It was down a full couple ticks. This follows a string of appearances in spring when Felix was below his previous velocity. That wasn’t a big deal then, but it’s a bigger deal now, with the season underway. According to PITCHf/x, Felix threw just two pitches at at least 91 miles per hour. Last year’s average fastball was 91.8. Every so often, there can be these blips — in one April start in 2013, Felix threw just one pitch north of 91 — yet this could be a developing pattern. And it’s worth taking a step back to consider just how far Felix’s velocity has fallen.
