While the AL East race appears to have tilted decisively towards the Red Sox over the past five weeks, an even more dramatic turnaround has taken place in the AL wild card race over an even longer timeline, one involving the Mariners and A’s. This one has yet to be decided, which is good news, because it’s practically the last race standing in the Junior Circuit.

Through June 15, the Mariners were running neck-and-neck with the Astros despite a massive disparity in the two teams’ run differentials, a situation that — as I had illustrated a few days earlier — owed a whole lot to their records in one-run games (22-10 for Seattle, 6-12 for Houston). The A’s, though solidly competitive to that point, were something of an afterthought, far overshadowed by the Mike Trout/Shohei Ohtani show in Anaheim:

On June 16, despite placing Matt Chapman on the disabled list with a contusion on his right thumb, the A’s, who had lost to the Angels 8-4 the night before, kicked off a five-game winning streak, taking the two remaining games of the series that weekend, then two from the Padres at Petco Park and the first game of a four-game set against the White Sox in Chicago. Though they merely split a four-gamer on the South Side, they swept four from the Tigers in Detroit, sparking a six-game winning streak that also included two victories at home against the Indians. Remarkably, they’ve strung together two separate six-game winning streaks since then, as well, one against the Giants (a pair of walk-of wins) at home and the Rangers in Arlington from July 21 to 26 and then another from July 30 through August 5 at home against the Blue Jays and Tigers. Alas, that one ended on Tuesday night against the Dodgers.

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In the twentieth installment of this series, we’ll hear from three pitchers — Zach Duke, Kyle Gibson, and Trevor Hildenberger — on how they learned and/or developed a specific pitch.

Zach Duke (Mariners) on His Two-Seamer

“I didn’t start throwing a two-seam fastball until I got to Triple-A. My pitching coach there was a guy named Darold Knowles, an old-time lefty who could manipulate a baseball as well as anyone I’ve met. He said, ‘You know, Zach, have you ever thought about throwing a two-seamer?’ I said, ‘Well yeah; I throw one.’ He goes, ‘No, a real two-seamer.’ I said, ‘What do you mean?’

“He told me to move my thumb up a little bit on the ball, and put a little pressure sideways. He said, ‘Throw it. You’ll see.’ Sure enough, I throw it and the bottom drops out of the ball. All of sudden I had a true sinker. I thought to myself, ‘How did I get this far without knowing something like that?’ Read the rest of this entry »

Back in May, the Mariners agreed to a lease deal that would keep them in Safeco Field for another 25 years. At the time, I wrote that the Mariners appeared to be bucking a trend by foregoing public money for a new stadium in favor of staying where they were.

Then, last week, things seemed to change.

Predictably, this was not well received.

Five years ago, Zach Duke found himself in a sobering situation. The then-30-year-old left-hander had exercised an August 1 opt-out clause — he’d been pitching well for Cincinnati’s Triple-A affiliate — and his next opportunity was seemingly right around the corner. With 200 big-league appearances under his belt, it was only a matter of time until his phone rang and he was fielding offers.

Instead, all he heard was crickets.

“I was on the verge,” Duke admitted this past weekend. “When you make yourself available to every team and none of them want you, that’s a pretty good indicator that the end might be near. To be honest, I thought that might be it.”

After reinventing himself, though, he’s not only still pitching, he’s a wanted man. Earlier today, the Seattle Mariners acquired Duke from the Minnesota Twins in exchange for Chase De Jong and Ryan Costello. His appeal to the pennant contenders is apparent in the numbers. In 45 relief appearances covering 37.1 innings, Duke has a 3.62 ERA, a 58.5% ground-ball rate, and has yet to give up a gopher.

As reported by the indefatigable Ken Rosenthal and Emily Waldon of The Athletic, the Seattle Mariners acquired relief pitcher Adam Warren on Monday afternoon from the New York Yankees in return for bonus slot money.

Is it possible for a bullpen to be too good? Obviously, at some level, that’s a silly question: no lead is 100% safe and, consequently, a team should never stop surveying what it has. But there’s also the question of utility. Any given club is bound to play only so many high-leverage innings. While you’d rather have a good reliever in the game than a poor one, the stuff you can get in return for that good reliever may simply be more useful to your franchise. Warren has been used mainly in low-leverage scenarios this season. Consider: of the eight Yankee pitchers primarily used in relief this season who have thrown at least 20 innings, Warren’s entered the game in the second-least crucial situations overall, ahead of only A.J. Cole, who has more swingman-type utility than Warren.

Chasen Shreve has already been traded by the Yankees for similar reasons, Zach Britton’s arrival in the Bronx only making the competition for those high-pressure situations more fierce. Tommy Kahnle is still standing by if the team loses a reliever and there’s still depth remaining, including J.P. Feyereisen, who continues to refine his control, and Raynel Espinal.

Just to illustrate how Warren’s skill are wasted by using him in the low-leverage innings available, just compare his performances to other relievers with 20 innings pitched and a game-entrance LI with 0.1 of Warren.

The Mariners and Cardinals swapped relievers today, the latter sending RHP Sam Tuivailala to Seattle for prospect Seth Elledge. The deal gives Seattle a marginal bullpen upgrade in Tuivailala (probably over Casey Lawrence) for a stretch run that’s going to require them to continue winning close games. Every slightly better bullpen option is more meaningful in this situation than it is when looking at reliever value from a broader point of view. The deal is also a good fit for St. Louis, who acquires a comparable talent whose service-time calendar better aligns with their competitive schedule. Tuivailala is arbitration-eligible starting in 2020, when Elledge will probably be in his first or second year of big-league service.

Tuivailala is a fine middle reliever. He sits 93-96, will occasionally touch 99, and has two very average secondary offerings in an upper-80s cutter/slider and an upper-70s curveball. The Mariners have had success drafting low-ceiling, high-probability college relievers in the middle rounds of the last several drafts and quickly flipping them for mature big-league pieces on the margins. Elledge was the second pitcher Seattle traded from their 2017 draft class (JP Sears was sent to the Yankees for Nick Rumbelow last fall), which means Seattle’s 2017 draft has technically yielded the most subustantial big-league return in all of baseball right now.

Seth Elledge is a big-bodied, crossfire reliever with a mid-90s fastball and plus breaking ball. He was a 2017 fourth-round pick out of Dallas Baptist, a college that parades hard-throwing relievers into pro ball annually. He has a 54:14 strikeout-to-walk ratio in 38.1 innings. He might eventually be better than Tuivailala because the breaking ball is better. It’s reasonable to project a 2020 debut for Elledge, though has a non-zero chance to debut next year.

They can’t all be Mike Trout, and this year, with the Millville Meteor posting a career-best 191 wRC+, the rest of the center-field pack has been as unproductive as any time in recent history. The collective 95 wRC+ recorded by all center fielders (including Trout) is the lowest it’s been since 2006, back when Trout was a high-school freshman.

Even with that fairly modest production, only a small handful of contenders — which for this series I’ve defined as teams with playoff odds of at least 15.0% (a definition that currently covers 15 teams) — are receiving less than 1.0 WAR from their center fielders, which makes them eligible for a spot among the Replacement-Level Killers.

By the way, since I don’t have anywhere else to put it — this is the last article in the series, since the RLK concept doesn’t work so neatly for pitchers and just one AL team has a DH who could be classified a Killer. Sorry if that was awkward; continue as you were…

There are few things that can make us feel more anxious than when we realize that people we consider our friends don’t enjoy the same things we do. Music, comedy specials, how much to go outside. There’s a little daring in liking things, especially when we like them deeply. By professing that we like something, we invite someone else to say that they don’t like that something, and then suddenly, there is one less thing that knits us to that someone.

Not liking the same little somethings is fine; I like eggplant and I have friends who don’t and it has never mattered, not even one time. But it can be hard to suss out in advance which little things, when pulled open, will lead to the bigger somethings that do matter. And so sharing the things we like can make us feel nervous. Perhaps you, the eggplant disliker, don’t care for its texture. That’s fine; eggplant has divisive mouthfeel. But maybe you don’t like it because you prefer the meaty taste of the human persons you have folded up in your basement freezer. That’s considerably less good! I went in liking eggplant and came out knowing you’re a murderer. Friendship can be dicey in this way, but I guess we have to risk it.

So here’s what I like. I like watching Jean Segura play baseball.

I liked this single, on a ball just above the zone.

The Rays lost a one-run decision in Miami Monday night, and it didn’t matter. I’m sure it mattered to the Marlins, and I’m sure it mattered to the Rays, but it didn’t really matter in the standings. Not as far as the playoff race is concerned. In the hunt for the AL’s second wild card, the Rays are in fourth place, but they’re separated from the first-place Mariners by 11.5 games. The Angels are 11 games back, and the A’s are the nearest competition, at eight behind. Nothing is actually yet set in stone, but it feels like we know the AL’s five playoff teams before we even reach the Fourth of July.

In some other universe, not much is different, except for everything. In this other universe, teams have win-loss records that match their run differentials. If you arrange by Pythagorean records, the Mariners still hold the second wild card, but they’re only one up on the Angels. They’re two up on the A’s, and they’re two and a half up on the Rays.

And then there’s the universe where everything goes according to BaseRuns. The inputs are the same as they are here, but the outputs simply make more sense. If you arrange by BaseRuns records, the Rays take over the lead for the second wild card. They’re a half-game up on the Mariners, and then there’s a little more room before the A’s and the Angels. According to the only standings that matter to us, the Rays are out of it. Basically everyone behind the Mariners is out of it. According to what you’d expect would have happened, there would be a tight race. In those other universes, there’s stress. There’s a far greater degree of uncertainty.

Not so. The Mariners have found a separator. They’ve pulled well away from all of their wild-card competition, and they’ve done so by being the clutchiest bunch of clutches that ever clutched.

In the fourteenth installment of this series, we’ll hear from three pitchers — Yoshihisa Hirano, Joe Musgrove, and James Paxton — on how they learned and/or developed a specific pitch.

Yoshihisa Hirano (Diamondbacks) on His Splitter

“I started throwing it when I turned pro in Japan. The truth is, when I was in college, I was able to get hitters out without having a splitty. A fastball and a slider was enough. When I got to the pros, there was a lot of talk of needing a pitch that comes down and about how there’s more success with that pitch. I started toying with it a little bit my last year of college, and when I got to the pros I started using it.

“Kazuhiro Sasaki was a big splitty-forkball thrower. There are some books about him, and I studied those. No one really taught me anything. I just went out and started playing with it, checking the books on how he grips it. I found a grip that was comfortable for me. There are some guys who throw it the same way, but there are other pitchers in Japan who grip it differently, too. They have a different placement within the seams.

Hirano’s splitter-forkball.
