Joey Wendle has been scorching the baseball. The Tampa Bay Rays infielder/outfielder is slashing .350/.405/.536 over his last 50 games, and he’s been especially torrid in his last 10. Wendle has 17 hits in his last 39 at-bats, pushing his season mark to a heady .300/.349/.429.

Pair those numbers with his defensively versatility — he’s started 10 or more games at three different positions — and the result for the 28-year-old late-bloomer is a 2.7 WAR that ranks first among AL rookies. Wendle is legitimate Rookie of the Year candidate.

His offensive output is surprising, but it’s by no means shocking. Wendle batted a solid .285 with a .441 slugging percentage in 380 Triple-A games, and he more than held his own in a pair of September cameos before coming to Tampa. The Rays acquired Wendle from the Oakland A’s last winter in exchange for Jonah Heim.

His left-handed stroke has never been better, and a big reason is that he’s no longer trying to build a better mousetrap. He’s simply being himself when he steps into the box.

“Personally, I feel the best swings are natural,” Wendle told me on a recent visit to Fenway Park. “I think some of my best swings came before I had any instruction. At the same time, you can slowly build them as you progress. I’d say that my career has gone from a natural swing to a bit of a forced swing, and now to a place where I understand my natural swing better.”

I asked the former West Chester University Golden Rams standout to elaborate on “forced swing.”

Evaluating pitchers is a real challenge. A combination of experience and knowledge can help one to better understand how variables like velocity, spin, and pitch mix translate to the majors. Even with that information, though, the influence of other factors — like injury risk, like a pitcher’s likelihood of responding to mechanical or mental adjustments — creates a great deal of uncertainty.

Nor is this a challenge that faces only prospect analysts like myself and Eric Longenhagen: even front-office execs who have the benefit of substantial resources — in the form both of data and personnel — have trouble reliably projecting outcomes for otherwise similarly talented young arms.

In my role as a talent evaluator both with FanGraphs and with a few major-league clubs, the question of how best to assess pitchers is obviously one to which I’ve returned with some frequency. In my recent efforts to get some final looks at certain top pitching prospects, however, I began to rethink how Eric Longenhagen and I should approach rankings this offseason. Three prospects, in particular, help to illustrate my concerns.

Tigers righty Matt Manning was the ninth overall pick in 2016, is an athletic 20-year-old who stands 6-foot-6, and was promoted to Double-A last week. In addition to that, he sat 94-96 and hit 98 mph in my look, mixing in a spike curveball that flashed 65 on the 20-80 scale. The positives here are numerous, and very few other minor leaguers could match even a few of these qualities.

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.

As noted by FanGraphs author Jeff Sullivan earlier this month, Tyler Glasnow has become a different and better pitcher. Being traded from the Pittsburgh Pirates to the Tampa Bay Rays is playing a part in that, but there’s more to his step forward than a simple change of scenery. The 25-year-old right-hander had already begun evolving.

Glasnow added a slider to his repertoire this year, giving him a third pitch to go with his high-octane heater and a curveball that has always flashed plus. He’s also started to elevate more fastballs, allowing him to take advantage of his velocity and above-average spin rate. Perhaps most importantly, he’s been getting his mechanics in order. Inconsistency has long been a bugaboo, with Glasnow’s 6-foot-8 frame getting much of the blame whenever he’s gotten out of whack with his delivery.

He’s back to a starting role now. The Pirates put him in the bullpen this spring, and he remained there until Tampa Bay finally pulled the trigger on an anticipated Chris Archer deal, acquiring Glasnow along with Austin Meadows and Shane Baz. The Rays promptly placed the high-ceiling hurler in their rotation, where they hope he remains for years to come.

Glasnow talked about the strides he’s made, particularly in terms of his repertoire and delivery, prior to a recent game. Also weighing in on the right-hander’s continued development is Tampa Bay pitching coach Kyle Snyder.

———

Glasnow on his two breaking balls: “They’re different grips, and the intent is different. Early in the count, I’m more of a curveball guy, while the slider is more of a put-away pitch. I would say my slider is the better of the two, but it’s easier for me to throw my curveball for strikes. I grip my slider like a traditional slider. My curveball is a pitch I release with the seams a little more parallel to my fingers.

Tyler Glasnow’s slider grip.

“The break is similar, they’re both 12-6, so I think it’s maybe hard for PITCHf/x, or whichever technology is being used, to [classify them]. In terms of usage, I’ve been throwing them pretty evenly. The curveball is a little slower and kind of just drops in the zone. The slider bites a little sharper. It comes in off a straighter plane, then breaks down.

It’s safe to say that the Tampa Bay Rays aren’t following a paint-by-numbers script. Casting convention to the wind, they employ “an opener,” they station their relievers on corners, they… do just about anything to gain a potential edge. As a small-market team in the A.L. East, they need to be creative in order to compete. It makes sense.

But not to everybody, and that includes a fair share of their fanbase. And even if it does make sense to the fanbase — sorta, kinda, at least — that wasn’t always the case. They had to be brought up to speed on the methods behind the madness, and that job fell squarely on the shoulders of the people who report on, and broadcast, the games.

Andy Freed and Dave Wills — the radio voices of Rays baseball — were front and center. According to the latter, they at least had a head start.

“We were trained a little bit by Joe Maddon,” said Wills, who along with Freed has called games in Tampa since 2005. “Joe was kind of the leader with doing different things, such as shifts and putting four men in the outfield. He’d set lineups differently than other people. So when it comes to what they’re doing now, we’re already in grad school. We’ve seen it, we’ve been there, we’ve done that.”

Which doesn’t mean advance warning from Kevin Cash wasn’t appreciated when the team introduced the “opener” concept. Wills may have an advanced degree in understanding-out-of-the-box, but what the Rays manager told him and his broadcast partner was straight out of left field. Read the rest of this entry »

Fringe Five Scoreboards: 2017 | 2016 | 2015 | 2014 | 2013.

The Fringe Five is a weekly regular-season exercise, introduced a few years ago by the present author, wherein that same author utilizes regressed stats, scouting reports, and also his own fallible intuition to identify and/or continue monitoring the most compelling fringe prospects in all of baseball.

Central to the exercise, of course, is a definition of the word fringe, a term which possesses different connotations for different sorts of readers. For the purposes of the column this year, a fringe prospect (and therefore one eligible for inclusion among the Five) is any rookie-eligible player at High-A or above who (a) was omitted from the preseason prospect lists produced by Baseball Prospectus, MLB.com, John Sickels, and (most importantly) FanGraphs’ Eric Longenhagen and Kiley McDaniel* and also who (b) is currently absent from a major-league roster. Players appearing within Longenhagen and McDaniel’s most recent update — and the updates published by Jeffrey Paternostro of Baseball Prospectus and John Sickels at Minor League Ball — have also been excluded from consideration.

*Note: I’ve excluded Baseball America’s list this year not due to any complaints with their coverage, but simply because said list is now behind a paywall.

For those interested in learning how Fringe Five players have fared at the major-league level, this somewhat recent post offers that kind of information. The short answer: better than a reasonable person would have have expected. In the final analysis, though, the basic idea here is to recognize those prospects who are perhaps receiving less notoriety than their talents or performance might otherwise warrant.

Brock Burke, LHP, Tampa Bay (Profile)
A third-round selection out of a Colorado high school in 2014, Burke has had the capacity to hit 95 mph for much of his professional career but has struggled to consistently hold his velocity from start to start. “I’d be down to 87-90 at times,” he told FanGraphs’ David Laurila in a post from June. “Now I’m more consistent with ranges, and my velo isn’t dropping at the end of games.”

Burke attributes at least part of his development to a Driveline Baseball program in which he participated with other Rays pitchers. “It was definitely beneficial,” said Burke. “It got me in better body shape, which has helped my accuracy and my velo.”

Whatever the cause, Burke has been excellent of late. Following an early-July promotion to Double-A Montgomery, Burke has recorded strikeout and walk rates of 33.6% and 6.2%, respectively, in 36.2 innings. The differential of 27.4 points between those two figures would represent the highest such mark among qualified Double-A pitchers. Burke was characteristically strong in his most recent start, recording an 8:2 strikeout-to-walk ratio against 28 batters over 7.0 innings (box).

Burke seemed to have the most success with his fastball in that start earlier this week. Here, though, is footage of the one his better curveballs:

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

Tanner Houck, RHP, Boston Red Sox
Level: Hi-A   Age: 22   Org Rank: 4   FV: 45
Line: 7 IP, 4 H, 0 BB, 1 R, 7 K

Notes
The Red Sox have been tinkering with Tanner Houck’s arm slot and pitch grips throughout the year in effort to find the best combination of pitch types for him. Earlier in the year that involved raising his arm slot and incorporating more four seamers into his mix, but now Houck’s fastball and arm slot look more like they did in college. His results have been better of late as he’s walked six and allowed nine runs combined over his last six starts. His low slot makes it easier for lefties to see the ball out of his hand and Houck will still need to find a way to counteract this issues to profile as a starter.

Mickey Moniak, OF, Philadelphia Phillies
Level: Hi-A   Age: 20   Org Rank: 14   FV: 40+
Line: 2-for-4, 2B, 3B

Notes
While his overall line is still disappointing, Mickey Moniak is slashing .298/.341/.465 since May 22. He’s made a subtle swing change that has him taking a using bigger leg kick with his knee driving back toward his rear hip (similar to the one Adam Haseley adopted while in Clearwater this year) and he’s also striding closed which has helped Moniak deal with stuff on the outer half, which had been a problem for him as a pro. I’ve asked teams for updated reports on Moniak and the pro side of the industry think he has tweener outfielder tools but acknowledges it appears he’s been playing a level ahead of his ability so far. The industry considers him a big leaguer but thinks it’s going to take some time.

Bryan Abreu, RHP, Houston Astros
Level: Low-A   Age: 21   Org Rank: 28   FV: 35+
Line: 6 IP, 4 H, 1 BB, 0 R, 10 K

Notes
Bryan Abreu has generated varying reports throughout the year, at times 92-94 with a 50 breaking ball and 40 control (which is barely a prospect) and others when he’s been up to 97, sitting 94-95 with big vertical action on one of two his breaking balls. He’s accrued double-digit strikeouts in two of his last three starts and has a 69:13 strikeout-to-walk ratio in 42.4 innings this season. The Astros are great at installing coherent pitching approaches into their prospects, most of whom are high-spin fastball/breaking ball guys who work up in the zone with their heaters, an approach which leads to more strikeouts. This, combined with Houston’s piggyback approach (where hitters don’t often see the same pitcher three or more times), leads to lots of strikeouts. I think the fastball (which is pretty straight) plays better out of the bullpen and I’m skeptical of Abreu’s short-term walk rate improvement because I’ve still got scouts questioning his command and it’s been an issue for Abreu in the past. I have him projected in relief and have added him to Houston’s team page on The Board.

Meandering Thoughts

Kiley wrote today about how he thinks the Rays have identified pitching subtypes that have skills to fit somewhere on the value spectrum between the perhaps unnecessary extremes of typical six or seven-inning starters and single-inning relievers. I’d like to talk about a few other oddball skillsets that might have a place on a 25-man roster as they help perform traditional and necessary on-field tasks but come in atypical packages. I’ve given them names that that the Cespedes Family BBQ kids will improve upon.

Waxahachie
This role, in which a player acts as relief specialist who can also play the outfield, has actually been utilized in the recent past and has been explored by other clubs in the minors even more recently. Outfielders with superlative arm strength or pitchers with plus athleticism could put an extra late-inning hitter or two at platoon disadvantage. The Astros have done this with Tony Sipp, bringing him in to face a lefty before sending him to the outfield while someone else gets righties out, and then returning Sipp to the mound to face another lefty. It seemed Houston might have hoped Rule 5 selection Anthony Gose would have been able to do something similar, but he didn’t make the team out of spring training and was returned to Texas.

Texas also has several candidates for this type of role in Gose (who is also a 70 runner and good defensive center fielder), James Jones (plus runner, plus outfield defense, low-90s with loopy breaking ball on the mound) and Jairo Beras (right-handed, mid-90s fastball, plus-plus raw power) who have all converted to the mound but have one or two other useful skills that could enable them to be deployed in the right situation.

James Jones, LHP, Texas Rangers from Eric Longenhagen on Vimeo.

Former big league OF Jordan Schafer would seem to have fit this archetype as well and he was used in various ways by different clubs (Atlanta played him in the outfield, the Dodgers tried to make him a base-stealing specialist for the 2016 stretch run and St. Louis tried him on the mound) but never in several different roles at once.

Rick Ankiel, who is attempting a big league comeback, is perfect for this kind of role, too. He could shuttle back and forth from the outfield to the mound a few times, while also pinch hitting when it makes sense to have a power-before-hit bat at the plate and pinch-running on occasion.

If someone like this already exists in the Rays system it’s RHP/OF Tanner Dodson, who the Rays wanted announced as a two-way player when he was drafted out of Cal in June. Dodson sits in the mid-90s on the mound and is also a plus runner who hit near the top of Cal’s lineup last year. He’s not polished in center and has a slap/slash approach at the plate, but there’s premium arm strength and speed here.

Pull-Side Infielder
There are certain hitters who don’t pull the ball enough to merit a shift but still pull the ball on the ground more often than hit it the other way and, perhaps, that means your rangiest infield defender should just play on the hitter’s pull side, even if that means swapping your 2B and SS, hitter-by-hitter. I think this idea is half-baked but I’d argue the Brewers are candidates for something like this right now as they’re playing Travis Shaw out of position at second base to shoehorn better hitters into their lineup. In my opinion, they should be swapping Jonathan Schoop and Shaw, hitter by hitter, something to maximize Schoop’s defensive touches and minimize Shaw’s. Perhaps my name for this type of thing is too narrow but the concept interests me. Tampa Bay has a slew of bat-first 2B-types who are either athletically viable all over the field in a dynamic defensive equation like this (Vidal Brujan, Nick Solak, Lucius Fox) or benefit from being hidden by it (Brandon Lowe, Taylor Walls, Jake Cronenworth)

Among the biggest changes in on-field strategy this year is the Rays’ use of an “opener,” or a starting pitcher who isn’t a traditional starter in style and is expected to throw only an inning or two. While certainly notable, the role itself isn’t my interest here. Rather, I’d like to consider how Tampa Bay has cobbled together a staff from Blake Snell and a cast of misfit toys.

From talking to sources in and around the Rays, the use of an “opener” wasn’t a purposeful strategic shift on the organization’s part, but rather an attempt by the club to deploy the talent present on the roster in the most effective way possible. Snell is the only pitcher who won’t get an opener in front of him, while the rest varies game-to-game based on matchups and other factors. Much like the best coach in the NFL, the Rays are using a player’s strengths and building a scheme around it rather than building a roster around a scheme.

Consider this characterization of Bill Belichick’s coaching philosophy by Greg Bedard of SI in the context of Tampa Bay and their pitching strategy:

On both sides of the ball, the scheme is multiple and adaptable both to personnel and to specific opponents. The Patriots are never a team that just ‘does what it does’ on either side of the ball. There must be a level of unpredictability.

Recently acquired former top prospect Tyler Glasnow has been notably better in his 12 innings with the Rays, but the role the right-hander typically fills (the longest outing on his pitching day, usually after the opener) is a one that could create a competitive advantage for the Rays in player procurement.

Tyler Glasnow allowed a solo home run on Tuesday, but outside of that, he was nearly untouchable. Over four innings, he allowed two hits, with, importantly, zero walks, and, importantly, nine strikeouts. Now, I know what some of you will say, because I’ve already seen it on Twitter. “Who cares? It was the Orioles.” And indeed, the Orioles suck. But when Glasnow made his Rays debut against the Angels the week before, he was similarly effective. There was a solo homer, but also a bunch of strikes and whiffs over three solid innings. Glasnow is two (semi-)starts into his Rays career, and he’s made an outstanding first impression.

It should go without saying that we’ll need a lot more data. With Tampa Bay, Glasnow has taken the mound all of two times, and that’s only two times more than zero. The Rays need to see Glasnow pitch a lot more often, and that’s what’s going to happen from here on out. We can’t say whether Glasnow already is better. But he *looks* better, and this kind of topic is right in my wheelhouse, since Glasnow is a pitcher whose results haven’t yet matched up with his stuff. Let me quickly walk you through what I find encouraging.

What kind of pitcher did the Reds get when they acquired Lucas Sims in the deadline deal that sent Adam Duvall to the Braves? By and large, they got a former first-rounder who has had spotty results in his smattering of big-league outings, yet little left to prove at the minor-league level. Blessed with plus stuff, he remains a tantalizing young talent.

The 24-year-old is getting smarter about his craft. Aware that he should “always be looking for that next step to stay ahead of the curve,” Sims has begun dabbling in analytics. He’s not diving in head first, but his toes are definitely in the water.

“I’ve recently gotten into it, but not to the point where I’m getting overwhelmed with it,” Sims explained earlier this summer. “I’m taking a couple of things here and there, basically whatever resonates with me. I’ve started getting into the spin-rate stuff, and which types of pitches are most effective in certain situations.”

The young right-hander had a colorful answer when asked if his four-seam spin rate is above-average.

“Yeah, but I don’t know exactly what it is,” Sims admitted. “I saw that it was green, and he said green is good.”

The ‘he’ in question was Alex Tamin — “one of our analytics guys” — whose official title with the Braves is director of major league operations. Color-coded assessments weren’t all that Tamin passed along. Sims has also begun “looking into effective spin, and trying to make sure I get true spin.”

Just how much further he dives in with his new team remains a question. Read the rest of this entry »
