Notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Note from Eric: Hey you, this is the last one of these for the year, as the minor-league regular season comes to a close. Thanks for reading. I’ll be taking some time off next week, charging the batteries for the offseason duties that lie ahead for Kiley and me.

D.J. Peters, CF, Los Angeles Dodgers
Level: Double-A   Age: 22   Org Rank: 7   FV: 45+
Line: 4-for-7, 2 HR, 2B (double header)

Notes
A comparison of DJ Peters‘ 2017 season in the Cal League and his 2018 season at Double-A gives us a good idea of what happens to on-paper production when a hitter is facing better pitching and defenses in a more stable offensive environment.

Reports of Peters’ physical abilities haven’t changed, nor is his batted-ball profile different in such a way that one would expect a downtick in production. The 2018 line is, I think, a more accurate distillation of Peters’ abilities. He belongs in a talent bucket with swing-and-miss outfielders like Franchy Cordero, Randal Grichuk, Michael A. Taylor, Bradley Zimmer, etc. These are slugging center fielders whose contact skills aren’t particularly great. Players like this are historically volatile from one season to the next but dominant if/when things click. They’re often ~1.5 WAR players who have some years in the three-win range. Sometimes they also turn into George Springer.

Cal Stevenson, OF, Toronto Blue Jays
Level: Advanced Rookie   Age: 21   Org Rank: NR   FV: 35
Line: 3-for-4, 2B, 4 SB

Notes
College seniors are expected to dominate short-season leagues after signing but what Cal Stevenson has done merits some discussion, in part because he played through a hand injury this spring that may have clouded his actual skill. Stevenson has a .513 OBP at Bluefield because he has walked nearly three times more often than he’s struck out. He’s also stolen 21 bags in 22 attempts since signing. These numbers corroborate scouting reports which compliment Stevenson’s plus speed and bat-to-ball skills before noting his likely corner-outfield defensive projection and lack of characteristic power for the position. But let’s keep an eye on this guy because Toronto has a track record of making swing adjustments to bat-first college players that have helped those players become more viable prospects.

No team plays a completely balanced scheduled over the course of a season. Some divisions, naturally, are better than others. Because intradivisional games account for roughly 40% of the league schedule, there is necessarily some irregularity in the strength of competition from club to club. Interleague play, which represents another 10% of games, also contributes to this imbalance. Given the sheer numbers of games in a major-league campaign, the effect of scheduling ultimately isn’t a major difference-maker. Talent and luck have much more influence over a club’s win-loss record. In any given month, however, scheduling imbalances can become much more pronounced.

Consider this: at the beginning of the season, just one team featured a projected gain or loss as large as three wins due to scheduling. The Texas Rangers were expected to lose three more games than their talent would otherwise dictate. Right now, however, there are eight teams with bigger prorated schedule swings than the one the Rangers saw at the beginning of the season — and those swings could have a big impact on the remaining pennant races.

To provide some backdrop, the chart below ranks the league’s schedules, toughest to easiest, compared to an even .500 schedule.

The Diamondbacks have a pretty rough go of it. Outside of five games against the Padres, the other “worst” team they play is the San Francisco Giants. They have one series each against the division-leading Astros, Braves, and Cubs along with a pair of series against both the Dodgers and Rockies. If Arizona were chasing these teams for the division or Wild Card, their schedule would present them with a good opportunity for making up ground. Given their current status, however, it just means a lot of tough games down the stretch.

A few weeks ago, when the A’s traded for Mike Fiers, I couldn’t think of anything worthwhile to say. It’s not that I thought it was a bad move — it’s that I thought it was a boring move, an unremarkable move. A very modest rotation upgrade that would be hard to dress up for FanGraphs readers over 900 words. I tried — I dug into all the familiar statistics and websites — but nothing jumped out. The Mike Fiers trade, to me, belonged in the same transaction category as the Aaron Loup trade. It was a move that happened that I didn’t need to analyze.

Fiers has started three times for the A’s. The A’s have won all three games, and Fiers has allowed three runs over 18.1 innings. Even more, he’s allowed only one walk, while racking up 21 strikeouts. In a short amount of time, Fiers has made himself remarkable. He’s done enough to draw my attention again. When a player goes on a hot streak, it’s natural to wonder what might be different about him. Sometimes — many times — a hot streak is just a hot streak. Fiers, though, has indeed made a few tweaks. Understanding it’s always impossible to conclude that a given tweak has directly led to greater success, let’s take a look at how Fiers has changed since getting to Oakland.

There are a lot of things going right in Oakland these days. For one thing, there are early indications that a red-hot rental and home-ownership market might finally be cooling off, even if only slightly (and very tentatively), thereby bringing four walls and a roof somewhat closer to reach for hundreds of thousands of ordinary Americans in the Bay Area. For another, the unemployment rate continues to drop (although wage growth is persistently and irritatingly slow to rise). And for a third, the Oakland Athletics have been the best team in baseball (west of Jersey Street) for over a month.

For a team to go 22-8 over any stretch, as the A’s have just done since July 10th, when they were last 10 games back of the Astros, requires a lot of things to go right. It requires Tony Sipp to hang a slider to Matt Olson. It requires a sweep of Texas on the road. It requires, in short, a little bit of that fairy dust that seems to have been scattered around the HoHo Coliseum since the days when Scott Hatteberg and Jonah Hill wandered those green fields — and the A’s have had that and all these things. But it also requires a lights-out bullpen, which the A’s have manifestly also had in recent days, and it’s this feature of the club’s recent experience on which I’d like to focus for a moment, because it wasn’t clear at the beginning of the season that this level of bullpen success was something the A’s would achieve or even necessarily aspire to.

The 2017 edition of the Oakland bullpen mostly sucked. By FIP (4.44), it was the ninth-worst in the game, by ERA (4.57) the sixth-worst, and by WPA, which is as close a measure as you can get to answering the question “was this bullpen good when it counted?” it was rock-bottom — the very worst in the game. If all you knew about the 2018 edition of the A’s pen is that it would no longer include Ryan Madson (who recorded a 2.06 ERA last year), you might project that it would take a step backwards this year, even after accounting for the winter additions of xwOBA darlings Ryan Buchter, Chris Hatcher, and Yusmeiro Petit in a busy offseason for Billy Beane.

Once upon a time, 12 teams and 15 years ago, Edwin Jackson was a Dodgers phenom who outdueled Randy Johnson in a major-league debut that happened to fall on his 20th birthday. Six trades, one All-Star appearance, one no-hitter, and several free-agency signings — some lucrative, some humbling — later, he’s the co-holder of a record for colorful laundry. Forget the “E Jax” nickname, the 34-year-old righty should be known as “Transaction Jackson.” Suddenly, he’s come back from the brink of professional oblivion to pitching as well as he has in half a decade with a performance that has not only helped the upstart A’s take possession of the second AL Wild Card spot, but has almost exactly coincided with their surge past the Mariners.

Jackson, who tied Octavio Dotel’s major-league record of 13 teams played for when he donned the green and gold for the first time, has been on quite an odyssey since that 2003 debut. He’s been traded in deals involving Danys Baez and Lance Carter (from the Dodgers to the Devil Rays in 2006), Matt Joyce (from the Rays to the Tigers in 2008), Curtis Granderson, Max Scherzer, and Ian Kennedy (from the Tigers to the Diamondbacks in a three-way, seven-player deal in 2009), Daniel Hudson (from the Diamondbacks to the White Sox in 2010), Mark Teahen and Jason Frasor (from the White Sox to the Blue Jays in 2011), and Dotel, Corey Patterson, Marc Rzepczynski, and Colby Rasmus (from the Blue Jays to the Cardinals on that same July 27, 2011 day, without even getting to suit up for Toronto). In his first taste of free agency, he signed a one-year, $11 million deal with the Nationals in February 2012. In his next one, he signed a four-year, $52 million deal with the Cubs in December 2012 — the first big free-agent deal of the Theo Epstein regime — but after a so-so first season (8-18, 4.98 ERA, 3.79 FIP, 2.0 WAR), his performance deteriorated to the point that in mid-2015, having delivered just an additional 0.8 WAR and converted to a relief role, he was released with $15.63 million remaining on his contract.

It’s at that point, on July 27, 2015, where this particular journeyman’s journey through the majors reached the lightning round; since then, Jackson has pitched for the Braves (2015), Marlins and Padres (2016), Orioles and Nationals again (2017). Over that three-season, six-team span (including his final months with the Cubs), he threw 215.2 innings with a 4.92 ERA, 5.24 FIP and -0.6 WAR, the last mark the second-lowest total of any of the 204 pitchers with at least 200 innings in that span. In his three starts for the Orioles and 13 for the Nationals last year, Jackson pitched to a 5.21 ERA and a career-worst 6.14 FIP in 76 innings, “good” for -0.3 WAR.

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.

The A’s occupy one of the AL’s two wild-card slots, and the other day they picked up Mike Fiers. They’re about to use him out of the rotation. I tried — I promise — to come up with some kind of Mike Fiers article, but I couldn’t do it. I didn’t think it would be interesting. The A’s added a below-average starter, but, into the rotation he goes. That might be the real story here, how the A’s have gotten where they are despite a patchwork rotation that no one expected. The A’s have given Brett Anderson nine turns. They’ve given Edwin Jackson — literally Edwin Jackson — eight turns. Fiers probably will help, if only for the fact that he can reliably pitch. The group he’s joining appears paper-thin.

Which isn’t to suggest that I don’t think much of Sean Manaea. Manaea, at least, has been a familiar constant. But there’s a surprise in here, too, a guy without whom the A’s would be struggling. Contact rate measures bat-to-ball contact per swing attempt. The lower the contact rate, the better a pitcher is at generating whiffs. I looked at every starter this year with at least 50 innings. The guy with the lowest contact rate allowed is Chris Sale. In second is Patrick Corbin. In third is Max Scherzer. In fourth is Trevor Cahill. The A’s signed Cahill for $1.5 million in the middle of March, seemingly as a response to losing Jharel Cotton. Cahill’s started 13 times, and he’s ended up an absolute bargain.

On June 15, the A’s lost to the Angels 8-4. For Oakland, it was their fourth consecutive loss, and it dropped them to a record of 34-36. At that point, the A’s were 11 games back of the Mariners, and while the underlying numbers suggested the standings should’ve been an awful lot closer than that, they weren’t, and there was little the A’s could do. You’ll remember it seemed like the AL playoff picture was already decided. The Mariners had a firm grip on the second wild card.

That race is now officially tied up. The A’s and the Mariners are both 18 games over .500. In the Mariners’ defense, it’s not like they’ve collapsed — since June 16, they’ve gone a mediocre 18-20. The A’s have gone a baseball-best 30-10. The Mariners have spun their wheels, while the A’s have caught fire. It looks like a coin flip the rest of the way. The playoff picture is settled no more.

How is it that the A’s have surprised as much as they have? How is it that baseball’s lowest opening-day payroll is currently tied for a playoff spot? Much credit has to go to the bullpen, led by Blake Treinen, Lou Trivino, and, now, Jeurys Familia. The bullpen has been incredible when it’s had to be. But as is always the case, this has been a team effort. Matt Chapman is a member of that team I’d like to bring to your attention.

Eugenio Suárez played in the All-Star Game earlier this month, so in some respects he’s not under the radar. But in many ways, he really is. The Cincinnati Reds third baseman is slashing .301/.387/.581, and he leads the National League in both wRC+ and RBIs. Were he playing in a bigger market, those numbers would make him… well, a star. Which he is… in relative anonymity.

Opposing pitchers certainly know who he is, and that’s been especially true this past week. Going into last night, Suárez had homered in five consecutive games, raising his season total to 24. That’s two fewer than last year’s career high, which came in his third season in Cincinnati. Count the Tigers’ former brain trust among those who didn’t see this coming. In December 2014, Detroit traded the then-23-year-old to the Reds for (gulp), Alfredo Simon.

“I don’t think anything has really changed,” Suárez claimed when I asked him about his evolution as a hitter. “I just play baseball like I did before. I’ve always been able to hit, just not for power like last year and this year.”

He attributes the power surge to maturity and hard work in the offseason. Asked to compare his current self to the 17-year-old kid who signed out of Venezuela in 2008, Suárez said the biggest difference is physicality. Read the rest of this entry »
