At 48-57, the Atlanta Braves are nowhere near this year’s playoff race. Braves fans can look forward to a brighter future, however, as Atlanta placed nine prospects on KATOH+’s most recent top-100 list. Ozzie Albies, who is arguably the most promising of those prospects, made his big league debut last night, starting at second base.

Although he’s a 20-year-old who was born in 1997 (!), Albies’ minor-league performance suggests he’s ready for another challenge. He slashed .285/.330/.440 at Triple-A, with an exciting 21 steals. Despite his small stature, Albies popped nine homers in Triple-A, resulting in a respectable .156 ISO. Albies’ offensive performance would be compelling for any infield prospect. And coming from a 20-year-old middle infield prospect, it’s extremely compelling. Read the rest of this entry »

The Mets have called up uber-prospect Amed Rosario to take over at shortstop. Rosario his more than earned this opportunity through his performance in the minors. Despite spending just two months at Double-A, the Mets started Rosario at Triple-A this year, and he rose to the challenge by hitting .328/.367/.466.

Rosario’s offensive performance has been impressive, but it’s less impressive after accounting for his environment. He’s played in the hitter-friendly Pacific Coast League, with half of his games coming in the hitter-friendly Las Vegas ballpark. Still, his 16% strikeout rate coupled with his speed (19 steals, tied for third in the PCL) and propensity for hitting doubles and triples (his seven triples are tied for eighth in the PCL) is encouraging.

Rosario’s hitting isn’t what makes him a stud prospect, however. More impressive than his offensive numbers is that he’s produced them while playing shortstop as a 21-year-old. A shortstop does not need to hit all that much to be a useful big leaguer — the average shortstop has hit .257/.309/.402 (85 wRC+) this year — so any sign of offensive life from a shortstop prospect is encouraging. And since he’s only 21, there’s a very good chance that he will grow as a hitter as he matures. Read the rest of this entry »

In the table below, you’ll find a treasure trove of information pertaining to the prospects who changed hands this trade deadline. There were 67 of them in all. Since there was a flurry of early trade activity this year, I’m using a liberal definition of “trade deadline” that considers all trades since the July 13th Jose Quintana deal. For reference, I performed a similar exercise last year. Read the rest of this entry »

The Dodgers traded for Yu Darvish. Below are the projections for the prospects the Rangers received in exchange for Darvish’s services.

Willie Calhoun, 2B/LF/DH (Profile)

KATOH: 9.4 WAR (15th)

KATOH+: 8.9 WAR (24th)

Calhoun has hit a rock-solid .298/.357/.574 at Triple-A this season as a 22-year-old second baseman. His power numbers have been undoubtedly helped by the PCL and he doesn’t exactly look like a premium athlete. But still: Calhoun’s blend of contact and power makes him extremely exciting. His defense, however, is suspect. Clay Davenport’s metrics say his defense at second has improved this year, but going from unbelievably bad to merely really bad doesn’t do much to help Calhoun’s case. Calhoun is a prospect without a position for now, so a move to the American League makes a ton of sense. KATOH had Calhoun as the Dodgers’ second-best prospect, behind Alex Verdugo.

The Astros acquired Francisco Liriano in exchange for Nori Aoki and Teoscar Hernandez. Below are the projections for Hernandez, who is the sole prospect headed to the Blue Jays. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Teoscar Hernandez, RF (Profile)

KATOH: 3.9 WAR (93rd overall prospect)

KATOH+: 4.7 WAR (96th overall prospect)

Hernandez has technically had stints in Houston both this season and last, but has spent most of 2017 with the Astros’ Triple-A affiliate. He only played one game with the Astros this season, coming in as a defensive replacement for Carlos Beltran. In Triple-A, he flashed his typical power-speed combination, racking up 12 homers and 12 steals in 79 games (though he was caught stealing seven times). In addition to his power and speed, Hernandez also draws a healthy amount of walks and has played solid right-field defense this year. He struck out in an acceptable 21% of plate appearances this year, which is a huge improvement from where he was a few years ago. Read the rest of this entry »

The Yankees traded for Sonny Gray. Below are the projections for the prospects the Athletics received in exchange for Gray’s services. Although he is a major part of this trade, I do not have a projection for James Kaprielian, who has thrown just 29 innings as a professional and zero since April 2016. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Jeimer Candelario, 3B (Profile)

KATOH: 4.4 WAR (108th)

KATOH+: 4.3 WAR (83rd)

Candelerio was slashing .266/.361/.507 in the Pacific Coast League this year, with a bunch of doubles and walks. The PCL has surely helped his power numbers a good deal, but his 12% walk rate illustrates that he does a decent job of controlling the strike zone. Defensively, Candelario has been an above-average third baseman this year in the minors. Although he’s been in the Cubs’ system forever, Candelario’s still just 23. A 23-year-old third baseman who can both hit and play average-ish defense is a fine prospect.

To put some faces to Candelario’s statistical profile, let’s generate some statistical comps. I calculated a Mahalanobis distance between Candelario’s Triple-A performance and every Triple-A season since 1991. In the table below, you’ll find the 10 most similar seasons, ranked from most to least similar. The WAR totals refer to each player’s first six seasons in the major leagues. Please note that the Mahalanobis analysis is separate from KATOH. KATOH relies on macro-level trends, rather than comps. The fates of a few statistically similar players shouldn’t be used to draw sweeping conclusions about a prospect’s future. For this reason, I recommend using a player’s KATOH forecast to assess his future potential. The comps give us some interesting names that sometimes feel spot-on, but they’re mostly just there for fun.

Isaac Paredes, SS (Profile)

KATOH: 5.2 WAR (76th)

KATOH+: 3.6 WAR (104th)

Despite being just 18 years old, Paredes is already in and has held his own in full-season ball, slashing .261/.341/.399 with a 14% strikeout rate in Low-A. That’s encouraging for an 18 year old, but it’s especially encouraging coming from an 18-year-old shortstop. Scouts are a tad skeptical of Paredes, citing a lack of physical projection and athleticism needed to stick at shortstop long-term. KATOH picks up on this too — by way of his height (5-foot-11) and lack of stolen bases — but still finds him very intriguing due to his combination of youth, contact and defense. As a Low-A hitter, Paredes has a long way to go, but he has several characteristics that often portend to big league success.

Three minor-ish trades went down on Friday night. The Mets acquired A.J. Ramos from the Marlins for Merandy Gonzalez and Ricardo Cespedes; the Nationals acquired Howie Kendrick from the Phillies for McKenzie Mills; the Orioles acquired Jeremy Hellickson from the Phillies for Garrett Cleavinger and Hyun Soo Kim.  Below are the projections for the prospects who changed hands. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

None of the players dealt last night are top prospects, and as a result, their likelihood of outcomes graphs are heavily skewed towards “no MLB”. Kyle Glaser recently found that fewer than one in five prospects traded at the deadline contribute more than one positive WAR season. All three of these pitchers seem like good bets to fall into that bottom four-fifths.

The Yankees acquired Jaime Garcia from the Twins for prospects Zack Littell and Dietrich Enns. You may remember that the Twins acquired Garcia less than a week ago. For their trouble, the Twins seemingly got a better return for Garcia than they gave up to acquire him. I have Huascar Ynoa projected for 1.9 WAR (by both KATOH and KATOH+), which is about half as much as Littell and Enns combined. It’s worth noting, however, that the Yankees are facing a 40-man roster crunch, so dealing Littell and Enns clears space for other prospects.

Below are the projections for the Twins’ newest prospects. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.
