Ariel Miranda sounds like one of those weird Disney Princess mashups that were fashionable clickbait last year — Click to see the Disney Princesses re-imagined as Sex and the City characters! Click to see the Disney Princesses re-imagined as members of the 2003 Philadelphia Eagles Secondary! Click to see the Disney Princesses re-imagined as America’s most infamous serial killers! — but he is an actual baseball pitcher who has come on of late and become a fairly interesting prospect of advanced age.

Miranda, a 6-foot-2 Cuban lefty, signed in May of 2015 after he defected and established residency in Haiti. He pitched across three levels during his first full season, finishing his initial domestic campaign with a solid eight-start run with Double-A Bowie. Miranda has passed 2016 in Triple-A (except for a two-inning shot of espresso with the Orioles early in July) and, while a 3.93 ERA from a 27-year-old isn’t exactly sexy, he’s flashed viable big-league stuff. His fastball will touch 95 mph on occasion and sits 90-93. Miranda has a quick, athletic arm and incorporates his lower half into a picturesque delivery that he doesn’t always finish. When he’s not driving the ball down, he lives either up in the zone or out of it altogether, something of which major-league hitters will take full advantage, but he’s capable of missing bats in the zone with his fastball. Miranda has been able to throw plenty of strikes this season, just not always where he wants to, and his control is ahead of his command.

A bevy of trades went down over the weekend, as this year’s trade deadline-season entered into full swing. Here are the prospects who changed teams the last couple of days, as evaluated by my newly updated KATOH system. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar methodology with consideration also for Baseball America’s rankings.

The Andrew Miller Trade

Clint Frazier, OF, New York (AL)

KATOH: 2.7 WAR
KATOH+: 4.7 WAR

Frazier had been promoted to Triple-A a week ago after slashing a strong .276/.356/.469 with 13 steals at Double-A this year. He pairs a high walk rate with decent power and speed, making him one of the most promising offensive prospects in baseball. Despite possessing average speed, Frazier plays mostly the corner-outfield spots these days, and hasn’t graded out particularly well there defensively. This suggests most of his big-league value will come from his hitting. Still, considering he’s a 21-year-old who’s already mastered Double-A, his future looks bright.

The Marlins had to pay a decently high price for Andrew Cashner. Jon Morosi is unironically tweeting about the ongoing Jeremy Hellickson sweepstakes. It’s important to establish the market context in which the Orioles have now traded for Wade Miley. It’s been obvious for months the Orioles could use some help in the rotation. The farm system didn’t make it realistically possible for them to look at higher-level solutions. They’d have to settle for what they could afford. Wade Miley is what they could afford, with the Mariners getting Ariel Miranda in exchange. There’s no money changing hands. This is about as uncomplicated as a move can get, with Miley being tremendously dull and still presumably helpful.

That’s the thing about the Orioles. Even though they’re a first-place team, it’s a team that had issues. Recent results be damned, the Orioles, in theory, can hit. We all know they can relieve. The rotation has been bad behind Chris Tillman — so bad that Wade Miley is an improvement. There aren’t many contending teams that Miley would make meaningfully better, but that’s the Orioles’ burden and blessing.

I’m going to let you in on a little writer secret. We don’t just write exclusively for traffic, but without traffic, there’s no FanGraphs. So we do want more clicks instead of fewer clicks, and when you’re composing a post about Chris Iannetta, it can be beneficial to disguise the subject. You might not be interested in reading about Iannetta, if you knew that’s what you’d be doing. But now you’re in, see. And you’re probably going to see this whole thing through, because the brain doesn’t want to acknowledge being teased. Now that I think about it, this isn’t a writer secret at all. This is just the Internet. Well anyway, there is something crazy here, so let’s get to that.

Jerry Dipoto didn’t set expectations too high for the Mariners, saying the goal was to build a team that could win 85 games or so. As part of that construction, Dipoto targeted bounceback candidates, and one of them was Chris Iannetta, who was coming off a down year at the plate. At the very least, Iannetta would improve upon the Mariners’ miserable catching baseline from 2015. But there was something even more promising in there: In 2015, Iannetta learned how to frame. He became one of the better catchers with regard to stealing or keeping strikes, and the story all made sense. It was easy to buy into Iannetta as a solid receiver. That, in turn, made it easy to buy into him as a solid regular catcher.

You know what they say about buying into things. Don’t ever bother buying anything. Iannetta’s bat hasn’t bounced back. But, far weirder, the receiving has completely deteriorated.

The Seattle Mariners are in a tough spot. They’re not a bad team, sitting a game over .500. By both Pythagorean wins and BaseRuns, they profile a few games better than that. Over the course of the rest of the season, they’re expected to continue to be a bit above average and our projections have them finishing at 83-79 for the year. That’s not a bad season — and if the team made a few big moves and caught a few breaks, they might even sneak their way into the playoffs where anything can happen. Unfortunately for the Mariners, that scenario isn’t very likely.

The division-leading Texas Rangers hardly seem invincible, but they’ve accrued a decent lead on the Mariners, while other divisional-rival Houston possesses the advantage both of more wins than the Mariners and more talent. This makes the M’s current chances of winning the division rather low. (For an interactive version of the chart, click here.)

They’re not out of it, as you can see, but they do face difficult odds. And keep in mind: these odds are reflective of the talent each club currently possesses on hand. Both the Rangers and Astros are expected to be buyers, and further moves by those teams figure to push their odds higher and the Mariners’ lower unless they counter with a move of their own.

As for the wild card, the task is equally as daunting. The chart below shows the wild-card probabilities only and do not include a team’s chances at the division. (Interactive version here.)

If you’re willing to hand the American League Central to Cleveland, that leaves four additional available playoff spots. Seattle is seventh on that list, with less than a 10% shot. That the top three teams all play in the AL East — and also expected to be buyers before the deadlines — makes Seattle’s predicament all the more obvious. The team isn’t likely to win, so the team should sell. How they should sell, though, is a bit more difficult to decipher.

We all knew Dan Vogelbach’s days in the Cubs’ organization were numbered. His lackluster range limit to first base, and if we’re being serious, even that’s a stretch. He didn’t have a future with the Cubs. Not only do they lack a DH, but they also have more quality hitters than they have lineup spots. A trade was imminent, and the Cubs finally pulled the trigger on Wednesday night, dealing the 23-year-old slugger for unheralded — yet effective — reliever Mike Montgomery and Double-A hurler Paul Blackburn. Triple-A pitcher Jordan Pries also heads to Chicago in the deal.

Dan Vogelbach, 1B, Seattle (Profile)

KATOH Forecast for first six seasons: 2.8 WAR

Vogelbach offers zero defensive value, which means he’ll need to hit a lot to get by in the big leagues. To his credit, however, his exploits in the minors this year suggest he might hit enough to make for a productive DH. He’s slashed a gaudy .318/.425/.548 in Triple-A, and has little left to prove in the minor leagues. KATOH isn’t crazy about Vogelbach on account of his defensive limitations, lack of speed and iffy contact numbers. Vogelbach’s power is excellent, but the other facets of his game threaten to chip away at his value.

The Cubs had no room for Dan Vogelbach. Hit though he may, the absence of the designated hitter in the National League was always an inhibitor for his future there, to say nothing of the wealth of young bats the Cubs have amassed at or near the major-league level. For several months, Vogelbach was an obvious potential trade candidate simply because the Cubs had nowhere to put him. Yesterday, that trade occurred: Chicago sent Vogelbach and Paul Blackburn to Seattle in exchange for Mike Montgomery and Jordan Pries.

Then a third baseman, Vogelbach won a 3-A state baseball championship in high school at Bishop Verot High School in Fort Myers. He tipped the scales at close to 280 pounds at the time and was asked to shed weight early in his pro career with the Cubs. He’s now listed at 6-foot, 250 pounds. There are certainly baseball players built like Vogelbach who are still able to effectively execute all aspects of their given position. Stories about Bartolo Colon‘s athleticism or Livan Hernandez’s flexibility are common in scouting circles and it’s not impossible that someone built like Pablo Sandoval or John Kruk can maintain enough lateral agility to effectively play a corner infield spot. Vogelbach doesn’t appear to be one of those players. He’s not a good athlete and has issues with range, footwork, flexibility and throwing accuracy. He’ll make the occasional, spectacular-looking, effort-based play but hasn’t shown enough technical refinement in his five pro seasons to convince scouts he can play a position.

Everybody wants Andrew Miller and Aroldis Chapman. If the Yankees elect to sell off, everybody will want Andrew Miller and Aroldis Chapman. I don’t need to explain to you why — they are two very obviously dominant left-handed, late-inning relievers. If the Yankees sell, they’ll ask for a high price. Teams, in turn, will pay high prices. You know how the trade deadline works.

People have linked the Cubs and the Yankees. The Cubs don’t need to improve much, but they’d like a steadier bullpen, and they could use a steady lefty. The Yankees present options. On a different tier, I figured the Cubs might have interest in Will Smith. I never once thought about Mike Montgomery. The Cubs just traded for Mike Montgomery. It might not be all they do, but it’s what they did today.

To begin with a gross oversimplification of a maddeningly complex sport, there are two ways to win a baseball game: score runs and prevent runs. Those two acts inform the predictive significance of run differentials and Pythagorean record and represent the reason I enjoy perusing leaderboards to see which teams are currently the best at run generation and prevention. We’re at the point in the season where the tops of the leaderboards aren’t terribly surprising – the Red Sox score frequently, the Mets don’t allow many runs, the Cubs are ridiculously great in both categories – but one team I’m still getting accustomed to finding near the top of the runs-scored leaderboard is the Mariners.

After years of battling mediocrity and a frustrating relegation to relative baseball obscurity, the Mariners have scored more runs than any American League team not named the Red Sox. With 315 runs scored through 63 games played, the Seattle is now averaging five runs scored per game — a rate they haven’t sustained over a full season since averaging 5.02 runs per game in 2002… you know, back when they had a designated hitter named Edgar Martinez, a second baseman named Bret Boone and a catcher named Dan Wilson. As offense has declined around the league during the last decade and a half, the Mariners’ offense has more than followed suit. In all but one season from 2004 to 2015, the Mariners finished anywhere from 11th to 14th in the AL in R/G. (Recall that, for a majority of that stretch, the American League consisted of only 14 teams.)

But now they’re scoring five runs a game – and are on a pace equivalent to 810 runs over a full 162-game schedule. Only five teams in the past five seasons have scored 810 runs and, of those five, all but the 2011 Red Sox made the postseason. And you might remember that the 2011 Red Sox team had to work darn hard to not make the playoffs. What the Mariners are doing right now is an undeniably good thing, and one that’s very much conducive to winning. And a little further digging reveals something endearingly quirky about the way the Mariners are scoring all of their runs.

This past Monday, against Cleveland, Seattle left-hander James Paxton recorded the highest single-game average fastball velocity of his career, at just under 99 mph. While sources differ on the matter, it was at least a mile per hour harder than his previous single-game high, which he’d established in his previous start (and season debut) at San Diego about a week earlier. Jeff Sullivan described that appearance against the Padres as “horrible and promising,” because Paxton had allowed eight runs in just 3.2 innings, but also exhibited a sort of arm speed he hadn’t previously. Monday’s start wasn’t horrible, at all. And even more promising.

There’s a mechanical explanation for why Paxton threw harder on Monday than he’d ever thrown before. But there’s also a change in pitch mix that led to one of the best starts of his life, too. And with those new mechanics and that new pitch mix also came a new mindset. It might be fair to say this is a new James Paxton.
