Below is an updated summer top-100 prospect list. Above are links to the top-10 lists for teams in each of the six divisions. Those include notes on why some of these prospects have moved up or down on their respective org list. For detailed scouting information on individual players, check out the player’s profile page, which may include tool grades and/or links to Daily Prospect Notes posts in which they’ve appeared this season. For detailed info on players drafted or signed this year, check out our sortable boards. The preseason top-100 list is available here.

With the trade deadline swiftly approaching, it’s time for some updated KATOH rankings. I know you’re not here to read about assumptions and caveats, so I’ll keep the non-list part of this article short and sweet.

• For each player, KATOH produces a WAR forecast for his first six years in the major leagues. There are drawbacks to scouting the stat line, but due to their objective nature, the projections here can be useful in identifying prospects who might be overlooked or overrated.
• KATOH+ incorporates Baseball America’s midseason top-100 list and Eric Longenhagen’s preseason FV grades for players excluded from BA’s list. Stats-only KATOH does not consider prospect rankings.
• These projections account only for minor-league stats. While I’ve done work with college players, I have not yet attempted to merge college and minor-league data. These projections also do not account for any major-league performance.
• All players with at least 200 minor-league plate appearances or batters faced in 2016 and/or 2017 were considered.
• This isn’t “Chris Mitchell’s Top 100 List,” and certainly not “FanGraphs’ Top 100 List.” This is simply the output from my far-from-perfect statistical model.

The draft is right around the corner, and KATOH’s here with some content. Today, I give you projections for the top-250 draft-eligible college players. This list considers all Division 1 players who logged at least 100 plate appearances or batters faced this season. These projections don’t just incorporate this year’s data, but also consider performances from 2016, 2015, and last summer’s Cape Cod League. I consider this to be a vast improvement over the work on amateur prospects I’ve done in the past.

I derived these projections using a methodology similar to the one I use for minor leaguers. I ran a series of probit regression analyses on historical data to determine the likelihood that a player will reach a variety of WAR thresholds (Playing in MLB, >0.5 WAR, >1 WAR, >2 WAR, etc.) through age 28. The resulting probabilities were used to generate a point estimate for each player’s WAR through age 28. The projections take into account performance, conference, age and height. They also account for defensive position for hitters and batters faced per game for pitchers. All of these factors are weighted accordingly based on the major-league careers of historical college players.

There are thousands of Division 1 baseball players, and the data is often unruly and prone to inaccuracies. Furthermore, determining who’s draft-eligible is often tricky, as birthdays and high-school graduation years are sometimes hard to track down. A bunch of front offices didn’t realize T.J. Friedl was eligible for the draft last year, so this isn’t just a me problem. All of this is to say that I can’t be 100% sure nobody was left off erroneously, so feel free to ask if your favorite college prospect isn’t listed.

I will provide further analysis on many of these players once we know where they end up, so check back next week. One quick observation: there’s been much debate over whether Louisville’s Brendan McKay should be selected as a pitcher or a hitter. KATOH sides strongly with Team Pitcher, as it ranks him No. 1 among college players as a pitcher and No. 191 as a first baseman. However, since he’s primarily focused on pitching to date, I suppose one could argue he has more development left than your typical 21-year-old hitter with his numbers.

Scouting Report
Barreto was signed by Toronto for $1.45 million back in 2012 and then traded to Oakland — along with Kendall Graveman, Brett Lawrie, and Sean Nolin — in exchange for Josh Donaldson. Bay Area sports talk radio still discusses the deal with frequency and bile, and largely considers Barreto the last hope for salvaging it, though Graveman and his sinker appear to be breaking out this year.

Scouting Report
Taveras signed for $2.1 million during the 2015 July 2 period and debuted in the DSL last year but, even in a brief time there, was clearly too advanced for that level. After 11 games in the DSL he came to Arizona for rookie ball. Scouts flocked to Arizona mid-summer to get a look at Taveras ahead of the trade deadline and he was a frequently discussed name in July. He has a very mature feel to hit, especially from the left side of the plate, with low-effort plus bat speed, barrel control, and a willingness to take what pitchers give him if a situation dictates it necessary for him to make contact. He also tracks pitches well, and scouts have a future 60 or better on the bat.

Scouting Report
The story of Martes’s acquisition is well told. The effects of the deal are obviously still resonating atop Houston’s prospect list, but perhaps more significant is the way that deal changed the way complex-level ball is scouted. Since Martes was unearthed in the GCL, more and more scouts are being assigned to rookie ball in Florida and Arizona. Some clubs have scout(s) here every year, others tailor their coverage based on where they are on the competitive spectrum, with rebuilding clubs more likely to have scouts here than ones who, if they make a trade, are hunting big leaguers instead of teenage lottery tickets. So while Martes has a chance to make a significant impact on an Astros club poised to compete for their division and, maybe, a World Series, the ripples through the industry created by his acquisition are arguably more significant. Okay, on to Martes as a prospect…

Scouting Report
The Blue Jays traded for international-bonus slots and were able to avoid completely blowing out their bonus pool to sign Guerrero in 2015, instead spending in a range that only benched them from big international spending for one year instead of two. While most 17-year-old international signees spend their first pro season in the Dominican, Guerrero was advanced enough to come stateside. Not only that, but after spending time in extended spring training (and often hanging around and attentively watching Jays’ Florida State League games at night in April and May), Guerrero skipped the GCL and was sent to the Appalachian League, where he was dominant.

Scouting Report
There were evaluators who didn’t know Benintendi was a draft-eligible sophomore as the 2015 season began. They had little reason to. He was solid but unspectacular as a freshman at Arkansas (in part due to injury), showing promising on-base skills but hitting for zero power while offering what appeared to be little physical projection. He didn’t play summer ball as a rising sophomore, either, as he recovered from a leg injury. He was allowed to do upper-body strength training and little else, so Benintendi bulked up. The following spring he was dominant, whacking 35 extra-base hits, posting a 1.205 OPS against mostly SEC opponents, and rocketing up boards into the top three or four for some clubs. The Red Sox drafted him seventh overall.
