Yerry Rodriguez, RHP, Texas Rangers
Level: Low-A   Age: 21   Org Rank: 14   FV: 40+
Line: 5 IP, 4 H, 0 BB, 6 K

Notes
If you’ve watched Padres righty Chris Paddack at all this spring, you’ve probably seen how he gets after hitters with his fastball at angles and in locations where they struggle to do anything with it, even in the strike zone. Though Rodriguez’s delivery doesn’t look anything like Paddack’s, the same concept applies, and Rodriguez is able to compete for swings and misses in the strike zone in a notable way. Lots of pitchers’ fastballs perform better than you’d expect given their velocity, but Rodriguez also throws hard. His changeup is good, and while I’ve taken umbrage with his breaking ball quality during in-person looks, he does have strong raw spin and his arm slot helps his breaker play up. I think there are a lot of strong components here and consider Rodriguez a dark horse top 100 candidate for next year.

Seuly Matias, RF, Kansas City Royals
Level: Hi-A   Age: 20   Org Rank: 1   FV: 45+
Line: 3-for-4, 2B, 3B
Notes
Matias’ 34% career strikeout rate is a sizable red flag that ultimately is what kept him off our overall prospect rankings. With a few exceptions, even the most whiff-prone big leaguers struck out less than that when they were in the minors. But so gifted and physically dominant is Matias that we think he’ll be effective, even if it’s in a streaky, inconsistent way like Domingo Santana or Carlos Gomez. As a teen, he was already posting exit velocities on par with burly, Quad-A type hitters. We hope he learns to take a walk, but “Randal Grichuk with more raw power” is a good player, so we’re cautiously optimistic that the Royals at least have a good big leaguer here, and a potential superstar if there’s contact/approach refinement, which is admittedly easier said than done.

Nolan Gorman, 3B, St. Louis Cardinals
Level: Low-A   Age: 18   Org Rank: 3   FV: 50
Line: 2-for-5, 2 HR
Notes
The Cardinals gave Gorman some reps with the big league team during spring training, and a scout told me they thought it would make Low-A, where Gorman struck out 37% of the time for a month of 2018, appear slower and easier by comparison. He has reached base in each of his 2019 games, and six of his 10 hits have gone for extra bases. We considered Gorman one of the more advanced high school bats in last year’s class (he and Jarred Kelenic were the only two in that top tier) and thought he might move quickly if the strikeout issues that popped up during his senior spring could be remedied. It looks like Gorman is just going to strike out a little more than is ideal, but he also appears poised for a quick move to the upper levels of the minors. When is the right time for promotion? I’d give opposing pitchers the chance to make adjustments to Gorman, and vice versa, which means waiting until mid-May when he sees Beloit, Quad Cities, Wisconsin, and Cedar Rapids for the second time. If he hits until then, and those clubs can’t find a way to get him out the second time they see him, perhaps we see Gorman in Hi-A just after he turns 19.

Joey Bart, C, San Francisco Giants
Level: Hi-A   Age: 22   Org Rank: 1   FV: 55
Line: 2-for-5, HR, 2B, BB
Notes
Nothing to see here as Bart should be expected to hit for power in the Cal League both because of its offensive environment and because last year he teed off on ACC competition, which is second only to the SEC, in my opinion. It’s ironic that the top two picks in last year’s drafts seem likely to be ready for the majors well before their parent club is likely to be competitive, but perhaps it will behoove the Giants to move Bart to Double-A semi-early this summer if for no other reason than to get him working with that pitching staff, which I think has more future big league teammates on it than the group in San Jose does.

Josh Naylor, DH, San Diego Padres
Level: Triple-A   Age: 21   Org Rank: 11   FV: 50
Line: 3-for-6, 2 2B
Notes
Naylor should be monitored closely because he’s the type of hitter who could explode if he makes a relevant approach change. He has both huge raw power and excellent bat control, but his willingness to offer at pitches he can’t drive had limited his power output until 2018, when he homered 17 times at Double-A. If he learns to attack the right pitches, he’ll hit so much that it won’t matter that he doesn’t really have a defensive home. As Naylor is just 21, we’re cautiously optimistic that he will. It’s too early to draw conclusions from his stats but his pull% is currently much higher than is usual.

Trying New Things
I noticed two odd things while combing box scores last night. First, Astros prospect Myles Straw (17th on the Astros list) has been playing shortstop. A quick perusal of the interwebs unearthed this article in the Houston Chronicle, which reports that the Astros will give this a try for a few weeks and see if Straw can actually play there. Their upper levels have been so crowded with outfielders that many of those players have been traded, and seeing as Straw’s best tool (his defense) is made redundant by Jake Marisnick, it makes sense to explore his defensive versatility.

Similarly, the Rangers are trying 1B/LF/3B Andretty Cordero at second base. Unlikely to do enough damage to profile at first (where he’s seen the most time), Cordero’s bat was still notable enough to include him in the Others of Note section of the Rangers list. Should he prove passable at second base, he’ll be much more relevant.

Former shortstop Javy Guerra of the Padres has moved to the mound, and I’ve been told he’s sitting in the upper-90s with natural cut. He’s on the San Diego 40-man.

Luis Robert, CF, Chicago White Sox
Level: Hi-A   Age: 21   Org Rank: 4   FV: 55
Line: 2-for-4, HR, 2 HBP

Notes
Off to hot start, Robert has multi-hit efforts in each of his first four games and has already stolen three bases and homered three times. After watching LouBob a lot last year (first while he rehabbed multiple injuries, then in the Fall League), I grew concerned about how his bat path might limit the quality of his contact (he sometimes struggled to pull pitches he should have) or his rate of contact, which we don’t have a large-enough sample to properly assess because of his injuries. So far, the pull-side stuff hasn’t been founded, as all but two of Robert’s balls in play so far this year have been to the right side of the field, and those were both pop-ups to the second baseman. He’s one of the more physically-gifted players in pro baseball.

Darwinzon Hernandez, LHP, Boston Red Sox
Level: Double-A   Age: 22   Org Rank: 2   FV: 45
Line: 5 IP, 2 H, 4 BB, 0 R, 10 K

Notes
We do not think Hernandez is a long-term starter and instead think he’ll be an elite bullpen arm. His fastball often sits in the upper-90s when he’s starting so it should at least stay there if he’s moved to relief and, though his feel for it comes and goes, his curveball can be untouchable at times. Maybe the strong early-season performances of Matt Barnes, Brandon Workman, and Ryan Brasier has stifled some of the disquiet about the Red Sox bullpen, but in the event that they need an impact arm, I think it’s more likely to be Hernandez than a piece outside the org. Some of this is due to the quality of the farm system, but Hernandez might also just be better than a lot of the options that will eventually be on the trade market. Read the rest of this entry »

Tuesday, the Rockies and 24-year-old right-hander German Marquez reached an agreement on a five-year, $43 million contract extension, with the deal first reported ESPN’s Jeff Passan. The contract includes a club option for a sixth year, though that becomes a mutual option if Marquez finishes at or near the top of the Cy Young voting twice during the life of the extension, which runs through 2023.

The deal encompasses one pre-arb year (this season), all three of Marquez’s arbitration years, and either one or two of his would-be free agent years, depending on what happens with that club option. He’s now on track to hit free agency at age 30.

Marquez is a pro scouting success story and an example of how development often continues after players have reached the big leagues. Th Rockies acquired him from Tampa Bay along with Jake McGee in exchange for Corey Dickerson (who Tampa later traded for fringe prospect Tristan Gray) and Kevin Padlo (who did not make our Rays prospect list). Marquez reached the big leagues in his first season as a Rockie.

Then just a competent strike-thrower with two plus pitches — a fastball and a curveball — Marquez was in the middle of our 2017 top 100 prospects list in anticipation of him developing a third pitch, which occurred during his 2018 breakout in the form of a new slider. After tinkering with his seldom-used changeup and a hard slider during the spring and first half of 2018, he leaned more heavily on the slide piece down the stretch in 2018 and was dominant toward the end of the season.

What’s next? Perhaps increased two-seamer usage, which could be especially meaningful as a way of keeping the ball on the ground in Coors Field. It’d be ideal for Marquez to continue refining his changeup but, despite his strike-throwing prowess, he has some issues with release consistency (it was better last year, but is still relatively varied) that might impede development in this area if you buy that things like feel and release consistency are indicators of change development, which I do.

We don’t know how a new CBA might have impacted Marquez’s free agency were he not to have signed a deal and hit the market at 28. The financial security afforded by extensions makes more sense for pitchers, who are at greater risk of suffering a career-altering injury. But Marquez hasn’t been injured since 2014 and is built like a tank, so perhaps he’s at less risk of breaking than, say, Blake Snell, who seemed to set the market for this type of extension a few weeks ago.

A 2.7 WAR contributor in 2017 and a 4.2 WAR arm in 2018 (who was trending up late in the year), Marquez is clearly part of a Rockies very long-term core that includes recently-extended Nolan Arenado, Kyle Freeland, David Dahl and whomever among the Ryan McMahon, Garrett Hampson, Brendan Rodgers, Raimel Tapia, etc. group turn out to actually be good. Daniel Murphy and Charlie Blackmon have deals running through 2021, and Trevor Story is under team control during that stretch, too.

Other than Ian Desmond, who has been a replacement level player for the last two years, there are no scary long-term deal on the books, so the Rockies should be free to pay to add to this competitive core while it’s together for the next three seasons, especially while 40% of their division is rebuilding. The most likely trade chips on the farm are Tyler Nevin and Colton Welker, who are blocked by Arenado, and McMahon/Murphy.

Late Tuesday night, Ken Rosenthal reported that the Tampa Bay Rays had agreed to a six-year, $24 million contract extension with 24-year-old second baseman and outfielder Brandon Lowe. Lowe is our 46th overall prospect, the top one in the 50 FV tier, and the No. 5 prospect in a loaded Rays system.

According to the Tampa Bay Times’ Marc Topkin, the deal also includes two club option years, which, along with incentives, could bring the total value to $49 million; if those options are exercised, Lowe will be 32 when the deal ends. Lowe will now obviously be making much more during his pre-arb seasons than he would have with standard contract renewals, but the possibility of overarching changes to baseball’s compensation structure in the next CBA currently make it impossible to evaluate the latter parts of the deal on Lowe’s end.

If he becomes the type of player I expect him to be — Lowe has power, walks at an above-average clip, and plays several positions including a passable second base, all of which makes me think he’s a two to three win player — a $4 million average annual value would make Lowe a bargain for the Rays. Based on Craig Edwards’ work at our site (and Driveline Baseball’s recent attempt to refine that research), 50 FV position player prospects like Lowe should be valued at $28 million, quite close to the value of his deal, excluding of the team option years. The AAV of the two option years, which would encompass Lowe’s age-31 and 32 seasons, is $12.5 million, almost exactly what D.J. LeMahieu received this offseason (age 30, two years, $24 million), and LeMahieu has been what we’d call a 50 in prospect parlance, as he was on average about a two win player during his tenure with Colorado.

This morning, we considered the catcher position. This afternoon, the positional power rankings take us out to left field.

Has batted ball data and modern defensive positioning altered the defensive spectrum? It likely won’t surprise readers to learn that the average wRC+ by position starts with first base and right field, but it may be revelatory to learn that the gap between right and left field has been pretty wide. The last four years, the average right fielder has produced an average wRC+ 4.75 ticks higher than his counterpart in left. The offensive bar at third base has also been higher on average than in left field during the last four years.

Why? Perhaps improved defensive positioning on the infield has enabled more bat-centric players to play third base when, in years past, they’d be at first. Most hitters are right-handed, and increased focus on pulling the ball in the air could have quickly made defensive range in left field more important than it has been in the past. The average sprint speed among left fielders is now on par with that at shortstop. Is it a long term, tectonic shift that should impact things like prospect evaluation? It’s hard to say definitively at this point because so much about the game is changing and still has the potential to change. But it’s worth discussing — eventually. For now, here are our current left fielders. Read the rest of this entry »
