MLB Draft League Data Darlings: Week 6

DATA DARLINGS (169) (8)

One aspect of the MLB Draft League that sets itself apart from other collegiate summer leagues is its implementation of technology and data. With the help of each team’s data coordinators, prospects of the league have information and analytics available in real-time to help evaluate, scout, develop their tools and game while it's distributed to the 30 Major League teams. This week marks the start of the second half of the Draft League, bringing in a blend of some top performers from the first half and new impact players who had a hot week.

1B Judah Morris, West Virginia

After a first half that saw him hit three home runs, nine doubles and post 21 RBI, Morris has started hot in his first week of the second half. In his first game, he hit two home runs at 103- and 106-mph exit velocities totaling more than 650 feet of distance. His raw power is apparent as in the first half he had a 17% barrel% and a 35% HHB% with an average exit velo of 92 mph and a max of 113! Morris is more than a powerful bat, as he has great plate discipline, highlighted by his low strikeout and high walk numbers. He only has a 15% K rate and a 16% BB rate, numbers often not seen with the archetype of batter Morris is; he is a one-of-a-kind. If he continues to perform how he has been, teams will begin to regret not taking the righty slugger in last week’s draft.

RHP Luke Delongchamp, Trenton

Delongchamp is one of the more interesting returning talents. He currently holds a 2.89 ERA and a 1.34 WHIP in his five games (two starts) this season, one of those starts coming in the second half. He has a unique arsenal, featuring a sinker, a changeup and a slider. His sinker is a runny two-seam that averages 16” of horizontal movement but can get up to 22” while sitting in the high 80s. His changeup has a similar shape but only has a 1500 spin rate and sits around 81 mph, a solid separation from the sinker. The changeup sees the best results, getting in-zone whiffs 22% of the time and overall whiffs 23% of the time. His third pitch, and arguably his best, is his slider which has a classic slider shape, getting short and sharp horizontal movement and slight vertical movement. It usually sits around 78 mph and gets whiffs 34% of the time. Delongchamp thrives on limiting baserunners, holding opposing hitters to a mere 5% BB%. His arsenal is built for getting batters out, which proves to be true as he has a 50% GB%. Look out for the Delongchamp hype to grow as the second half continues.

RHP Luke House, State College

The second Luke on this list, House was great for the first half champs. His 2.01 ERA is second amongst qualified Spikes, while his .183 batting average against is the team best. His arsenal is one of the league’s best, featuring a mid 90s fastball, depthy curveball, splitter, slider and sinker. The fastball tops out at 95 and gets up to 20” of IVB which he throws roughly 55% of the time. His sinker sits around 93 mph but gets more drop than his fastball, getting about 12” of IVB on average with 15” of arm side run. His slider is very sharp, getting only -1.3” of horizontal movement, but it is extremely effective. It gets a 36% Whiff%, 29% In-Zone Whiff% and a 32% Chase% while holding opponents to a 0% HHB% and a .134 xBA. His splitter is very unpredictable, which keeps batters guessing. It averages 5” of IVB and generates an eye-catching 42% Whiff%. His last pitch, a depthy, high-spin curveball, moves over 10” each of IVB and HB while getting whiffs 32% of the time. House is great at controlling his PAs, limiting batters to 7% BB% while holding them to a 29% K%. His mix of five pitches keeps batters on their toes, evident by his 31% Chase% and 28% Whiff% overall. The State College righty will surely be one of the premier arms in the second half.

C Matthew Rivera, Mahoning Valley

Rivera’s second half started off hot with the first mutli-homer game in all of the 2025 season and being named the half’s first Hitter of the Week. A returner from the Scrappers’ 2024 first half squad, Rivera has shown a very selective approach at the plate but making the most of every swing he takes. With only a 50% swing rate on pitches in the zone, he’s made contact on 92.3% of those with a perfect contact rate on all pitches swung at besides the changeup. With the approach, he’s been able to punish balls with a 37.5% Hard-Hit rate, averaging 85.2 mph in exit velocity and a max of 107.3 mph on a double. While three games is all he’s been featured in leading up to week two, Rivera’s production at the plate has allowed him to pace the league in slugging (1.000) and OPS (1.533).

SS Rayth Petersen, Williamsport

After a slow first two games (1-for-8, four Ks), a day off for the shortstop from Illinois-Chicago proved more than beneficial with back-to-back three-hit games that included two doubles and a home run. His first two games featured plenty of whiff (40%) and soft contact (74.9 mph avg EV) with a 0% BB%. But after his day off, Petersen featured a slightly more aggressive approach from 50% Z-Swing% to 88.9% and made contact 100% of the time. He also raised his average exit velocity to 85.9 mph and even put the ball in the air more with an 87.5% FB/LD% after beginning the week with a 50% groundball rate and 25% line drive rate.

C Irvin Escobar, Frederick

Leading the second half in hits with 11, Escobar’s 25 at bats have seen him put the ball in play 23 times. The Keys catcher has presented himself as a free-swinger with a higher chase rate than one may like but rarely whiffs on pitches with a 9.5% Whiff%. His bat-to-ball skills have resulted in a 93.5% Z-Contact% on a 67.4% Zone-Swing rate which has led to a small K% of 7.4%. Escobar has also been able to collect his hits with a 73.9% FB/LD% as only five balls in play did not reach the outfield.
