Keith Law released his AL East Prospect analysis today. Here is his blurb on the Jays.
Toronto Blue Jays
The emergence of two of the top teenaged prospects in baseball last year was somewhat mitigated by the regression of many top prospects, including three members of the Jays' Double-A rotation who ranked in my top seven for the organization last year.
1. Vlad Guerrero, Jr., 3B (ranked No. 2)
2. Bo Bichette, SS (ranked No. 17)
3. Anthony Alford, OF (ranked No. 44)
4. Nate Pearson, RHP (ranked No. 100)
5. Logan Warmoth, SS
6. Dan Jansen, C
7. Ryan Borucki, LHP
8. Eric Pardinho, RHP
9. Sean Reid-Foley, RHP
10. T.J. Zeuch, RHP
Non-top-100 prospects
Logan Warmoth was the team's first first-round pick, just a few selections ahead of Pearson, and he still projects as a solid-average regular or more between his defense at shortstop, above-average speed and sound swing that should produce plenty of contact. Dan Jansen had a breakout year in 2017 by staying healthy and getting new glasses -- it's hard to hit a ball you can't see -- hitting .323/.400/.484 at three levels, including Triple-A. He drew 38 unintentional walks against just 40 strikeouts and does make hard contact, projecting to hit eight-to-12 homers in the majors. He's a fringy defender overall, but pitchers like throwing to him, enough that he looks like a regular behind the plate, thanks to his bat.
Ryan Borucki will pitch at 90-93 with a 70 changeup and can reach back for more velocity as needed, with an average slider and an aggressive approach to attacking hitters. He also had his second straight full, healthy season after missing all of 2013 and nearly all of 2015 with elbow and shoulder issues. He could be a fifth starter for the Jays this year, with league-average upside in time. Eric Pardinho signed for $1.4 million, the largest bonus ever given to a Brazilian prospect, last July and earned raves from international scouts for his makeup and feel to pitch at such a young age. He's a little undersized, but everything else you could want in a pitching prospect is there: four pitches, already up to 94 at age 16, command, delivery, athleticism, feel to pitch. People just love this kid and believe he's going to be a big league starter, perhaps sooner than most 16-year-old prospects would get there.
Sean Reid-Foley's year was a disaster, with 22 homers allowed and a 5.09 ERA in 132.2 innings for Double-A New Hampshire. His stuff was there, but his command and his pitch selection got him into trouble, so while he has starter upside, he clearly isn't as far along as it seemed last year, when he made my top 100. T.J. Zeuch, their first-round pick in 2016, posted a 61 percent ground ball rate in high-A but made just 11 starts there around multiple DL stints. He has fourth-starter potential because he gets good plane from a high arm slot, but between his lack of durability and questions about an out pitch, he might not have much ceiling beyond that.
Samad Taylor (11) came over from Cleveland in the Joe Smith trade, having just turned 19 a few weeks before the trade deadline. He's a quick-twitch second baseman who shows bursts of speed on the bases and in his swing, with some physical maturity left ahead of him and the possibility of a move to center. He'll go to low-A Lansing this year as a teenager and has at least everyday player upside, depending on his growth and his plate discipline. Richard Urena (12) has yet to show any real progress in his plate discipline, walking just 28 times in 551 PA for Double-A New Hampshire, his career high in any full-season league, which makes it hard to profile him as more than a utility infielder. He's an above-average defender at short or second and has a little pop, but right now he looks like a chronic sub-.300 OBP guy. Right-hander Elieser Medrano (13) has been up to 94-95 with a hammer curveball, pitching a little bit in the GCL last year at 18, with starter upside depending on how his body fills out and development of his command.
Thomas Pannone (14) came with Taylor in the Smith trade; he's a strike-throwing lefty with a bunch of grade-45 or -50 pitches, but he has tremendous deception that has hitters swinging through fringy stuff, at least so far up through Double-A. Don't rule him out as a back-end starter. Justin Maese (15) was a favorite of mine in their system last year, but shoulder soreness shut him down for two months, and he was ineffective when he tried to pitch through it. Maximo Castillo (16) is a stocky Venezuelan right-hander with feel to pitch and some arm strength who punched out a quarter of opposing batters as an 18-year-old in the Appy League.
Shortstop Luis de los Santos (17) is fast and athletic and can play defense, with some bat-to-ball skills but not enough of an approach yet, drawing just six walks in 200 PAs as a 19-year-old in the GCL, with a few quick promotions to Lansing sprinkled into his season. He'll probably start in low-A this year, his age-20 season, which should give us a sense of whether his bat has a chance to make him a future regular. Hagen Danner (18) was the Jays' second-rounder in 2017, a strong-armed two-way player in high school who is at least starting his pro career as a catcher. He's a bat-first prospect, but he struggled in his pro debut in the GCL. Right-hander Jol Concepcion (19) was 93-97 last year and flashed a plus curveball, but he'll miss the start of 2018 after receiving a 60-day suspension for testing positive for a steroid. Catcher Riley Adams (20) has power and a plus arm, adequate receiving skills and too much swing-and-miss to profile as a solid-average regular, but he should at least make it as a backup.
I do not count Lourdes Gurriel Jr. as a prospect, as he played in Cuba's top league and signed a major league contract (for $22 million) with the Jays after defecting, but his first year here was not a success. The 23-year-old hit .229/.268/.339 between high-A and Double-A, showing just average bat speed, below-average running speed and adequate defense at second when I saw him.
2018 impact: Ryan Borucki seems likely to at least log some time in the Jays' rotation, which has Joe Biagini (5.73 ERA as a starter) penciled into the No. 5 spot and two oft-injured pitchers ahead of him.
The fallen: Max Pentecost, the 11th overall pick in the 2014 draft, played in just 72 games in 2017, bringing his career total to 171, and all the lost time seems to have dragged down his once-promising bat. He'll be 25 this year and still hasn't played a game above Class A. Jon Harris, the Jays' first-round pick in 2015, has been healthy but ineffective, giving up 20 homers in 143 innings in Double-A with a 5.41 ERA, struggling with the lack of a solid breaking ball and the fact that hitters seem to see his fastball too well.
Sleeper: The baseball world thinks so highly of Eric Pardinho that I am inclined to go along with them, even though he's just 16.
