Note from Eric: Hey you, this is the last one of these for the year, as the minor-league regular season comes to a close. Thanks for reading. I’ll be taking some time off next week, charging the batteries for the offseason duties that lie ahead for Kiley and me.

D.J. Peters, CF, Los Angeles Dodgers
Level: Double-A   Age: 22   Org Rank: 7   FV: 45+
Line: 4-for-7, 2 HR, 2B (double header)

Notes
A comparison of DJ Peters‘ 2017 season in the Cal League and his 2018 season at Double-A gives us a good idea of what happens to on-paper production when a hitter is facing better pitching and defenses in a more stable offensive environment.

Reports of Peters’ physical abilities haven’t changed, nor is his batted-ball profile different in such a way that one would expect a downtick in production. The 2018 line is, I think, a more accurate distillation of Peters’ abilities. He belongs in a talent bucket with swing-and-miss outfielders like Franchy Cordero, Randal Grichuk, Michael A. Taylor, Bradley Zimmer, etc. These are slugging center fielders whose contact skills aren’t particularly great. Players like this are historically volatile from one season to the next but dominant if/when things click. They’re often ~1.5 WAR players who have some years in the three-win range. Sometimes they also turn into George Springer.

Cal Stevenson, OF, Toronto Blue Jays
Level: Advanced Rookie   Age: 21   Org Rank: NR   FV: 35
Line: 3-for-4, 2B, 4 SB

Notes
College seniors are expected to dominate short-season leagues after signing but what Cal Stevenson has done merits some discussion, in part because he played through a hand injury this spring that may have clouded his actual skill. Stevenson has a .513 OBP at Bluefield because he has walked nearly three times more often than he’s struck out. He’s also stolen 21 bags in 22 attempts since signing. These numbers corroborate scouting reports which compliment Stevenson’s plus speed and bat-to-ball skills before noting his likely corner-outfield defensive projection and lack of characteristic power for the position. But let’s keep an eye on this guy because Toronto has a track record of making swing adjustments to bat-first college players that have helped those players become more viable prospects.

Performances from 8/26

Evan White, 1B, Seattle Mariners
Level: High-A   Age: 22   Org Rank: 2   FV: 45
Line: 3-for-4, 2B, 3Bho

Notes
We now have a full season of data to help us figure out whether Evan White’s weird profile is going to play. A plus-running backwards guy (bats right, throws left, a generally unfavorable combination due to the defensive limitations and platoon issues caused by both) who plays plus defense at first base, White was slugging .391 at the start of August, which is rather uninspiring for a college hitter in the Cal League. In August, however, White has 30 hits in 90 plate appearances and is slugging .763. He has made subtle changes to his lower half, drawing his front knee back toward his rear hip more than he did at Kentucky, and taking a longer stride back toward the pitcher. White is more often finishing with a flexed front leg, which has helped him go down and lift balls in the bottom part of the strike zone by adjusting his lower half instead of his hands. It’s a more athletic swing that was implemented before White’s explosive August, though he may just be getting comfortable with it now. Read the rest of this entry »

Bubba Thompson, CF, Texas Rangers
Level: Low-A   Age: 20   Org Rank: 5   FV: 45
Line: 4-for-6, HR

Notes
Were Bubba Thompson wrapping up his season with poor numbers, I’d be excusing it based on context. A multi-sport high-school athlete who had focused solely on baseball for just one year, Thompson also had his reps limited, after he signed last summer, due to nagging lower-body issues. I expected him to hang back in extended spring training and then head to Spokane in June. Instead, after a month in extended, Thompson was pushed by Texas to a full-season affiliate as a 19-year-old. He’s hitting .295/.350/.460 with 28 extra-base hits in 323 PAz and 28 steals in 35 attempts. He’s projects as a center fielder with power.

Johan Quezada, RHP, Minnesota Twins
Level: Low-A   Age: Turns 24 on Saturday   Org Rank: 46   FV: 35+
Line: 3.1 IP, 0 H, 0 BB, 0 R, 6 K

Notes
This was Johan Quezada’s first career appearance in full-season ball. An imposing mound presence at a towering 6-foot-6, he has recovered from the shoulder surgery that cost him all of 2017, and his velocity has returned. He sits 94-97 with extreme downhill plane created by his height, and he’ll show you an average slider every once in a while. Quezada’s breaking-ball quality and command need to develop as they’re understandably behind due to his limited pro workload. He’s a older-than-usual arm-strength/size lottery ticket. On the surface, he seems like a candidate for extra reps in the Arizona Fall League.

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.
