Mark Vientos, 3B, New York Mets
Level: Appy   Age: 18   Org Rank: 7   FV: 45+
Line: 3-for-3, 2B, BB

Notes
The Mets have made effectual changes to Mark Vientos’s swing since he signed. His stance has opened up and his hands set up in a way that has enabled him to lift the ball better than he did in high school, especially pitches on the inner half. His hands are more alive and powerful than they were a year ago, and Vientos has launched balls out the other way even when he doesn’t fully square them up. His size/build might eventually cause a tumble down the defensive spectrum (he’s been projected off of shortstop to, at least, third base since he was a high-school underclassman), which would mean power alone won’t be enough to enable him to profile. His early-career contact rates are positive, especially considering Vientos doesn’t turn 19 until December.

Bryse Wilson, RHP, Atlanta Braves
Level: Triple-A   Age: 20   Org Rank: 12   FV: 45+
Line: 8 IP, 1 H, 0 BB, 0 R, 13 K

Notes
Bryse Wilson touched 97 several times last night and sat 93-95 late in the outing. He pounded the zone with his fastball (72 of 98 pitches were for strikes) and blew it past several hitters up above the strike zone. His slider (mostly 83-85, though he lollipops some slower ones into the zone for first-pitch strikes) flashes plus but is mostly average and is only capable of missing bats when it’s out of the zone. Wilson’s changeup is fringey and firm, without much bat-missing movement, but the velocity separation off of the fastball is enough to keep hitters from squaring it up, and it’s going to be an effective pitch. The entire package (Wilson’s physicality and stuff) looks very similar to Michael Fulmer and Wilson’s delivery is much more graceful and fluid than it was when he was in high school, when scouts thought it would impact his ability to command the fastball and possibly move him to the bullpen.

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.

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

These daily notes are going to be different/sporadic this week, as I’ll be in Southern California for the Area Code Games in Long Beach and then PG All American in San Diego over the weekend. In today’s edition, I’ve got notes on some of the players I saw in Arizona over the weekend, and a reflection on a few specific aspects of our process as it relates to pitcher injuries.

First, a look at Dodgers lefty Julio Urias, who is rehabbing from surgery to repair a tear of his left shoulder’s anterior caspule. Urias threw 1.2 innings against the White Sox’ AZL team on Saturday in his second rehab appearance of the summer. He allowed just one hit and struck out four. His fastball sat 88-91 and topped out at 92, well below the velocity band he has displayed throughout his career, which was typically in the 92-95 range. A scout who was in attendance at Urias’s first rehab outing earlier in the week told me they also had Urias topping out at 92, which conflicts with what was reported just after that outing. Urias’s fastball command was much better in this brief look than it was in his often frustrating big-league appearances, and it has flat, bat-missing plane up in the zone. Overall. though, it’s a 45 fastball right now.

Urias’s secondaries were a bit less crisp than pre-surgery. I saw one slider and several curveballs (flashed plus, mostly average) which were also thrown with less velocity (71-74 mph) than Urias exhibited before injury (75-80). The pitch has good depth and tight snap when it’s down, perhaps not playing within the strike zone quite as well. Urias threw a few average changeups (including a first pitch cambio that Luis Robert foul-tipped) in the 80-83 mph range, but he lacked feel for keeping the pitch down and hung several of them in the top of the strike zone or above it.

Obviously, Urias is returning from a serious shoulder injury, and it’s possible his stuff will tick up with continued work. The Dodgers expect him to contribute to the bullpen in September and he need only wield a competent breaking ball remain left-handed for the next eight weeks to do that. Long term, it’s hard to say what’s going to happen here. Urias was once 6 fastball, 6 breaking ball, above-average changeup, plus command projection. Right now he’s a bunch of 45s and 50s.

Some Thoughts on Process

Before I start discussing some process-oriented stuff on our end, I want to give newer readers a crash course on how we assign FV grades to players and what they mean. A more detailed explanation can be found here.

The 2018 trade deadline has passed and, with it, dozens of prospects have begun a new journey toward the major league with a different organization. We have the prospects traded since the Manny Machado deal ranked below, with brief scouting snippets for each of them. Players highlighted in blue are not technically prospects, having exhausted rookie eligibility, but we felt they fell under our umbrella of evaluation anyway as they’ve spent a lot of time up and down in the minors this year. Plus, it’s just interesting to think about where they fit. Scouting info comes from both in-person looks and also a combination of scouts and front-office personnel to whom we are eternally grateful.

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.
