The Arizona Diamondbacks released their instructional league roster for the fall, and it’s filled with plenty of top prospects.

Due to the cancellation of the Arizona Fall League, MLB teams will have an instructional league to groom its young prospects. Prospects added to the roster gives them a chance to focuson their skills and strengths during the final months of the season.

As seen in the list above, there’s a bevy of top prospects on the instructional league roster with players like Robinson, Carroll, Perdomo, Thomas, Walston, Kelly and Jarvis, many of whom were added to Arizona’s 60-man roster this season and developed at its alternate training site in Scottsdale.

The Diamondbacks’ highly touted names were expected to be added considering the cancellation of a Minor League Baseball season and the AFL. However, there are several prospects who weren’t added to the 60-man roster that will get some play in instructs this fall.

Arizona’s collection of overseas talent will be on display this fall with notable players like Patiño, Justin Martinez, Espinal, Barrosa and Jhosmer Alvarez. Each of them have yet to turn 20 years old, and they’re worth keeping an eye on as they advance through the system.

The Diamondbacks added new prospects at the trade deadline. Mejía—acquired from the Miami Marlins in exchange for Starling Marte— and Fairchild—acquired from the Cincinnati Reds in exchange for Archie Bradley—will make their D-backs organizational debuts at the instructional league. Mejía made his MLB debut with the Marlins this season before the trade to Arizona. Fairchild hit a career-high 12 homers and 29 doubles over High-A and Double-A and played in the AFL last season.

All five prospects from the 2020 MLB Draft were added to the instructional league roster in Jarvis, Cecconi, Norris, Vukovich and Pfaadt. Of the group, Jarvis was the lone member on the D-backs’ 60-man roster this season.

The infield depth on the instructional league roster is a bit underwhelming, but full of versatile prospects including Alexander, English and Kennedy. Perdomo is the top name of the group, and Hill Jr.—Arizona’s fourth round pick in 2019— is another piece that can contribute. The outfield is loaded with top-tier prospects, and it will be interesting to see it all unfold over the fall.

Catcher is an intriguing position to watch develop. Daulton Varsho’s promotion to the majors leaves the D-backs' system a bit thin behind the dish. Miroglio wasn’t added to the 60-man roster, he batted .233 with two homers and 12 RBIs in 47 games with Double-A Jackson last season. Garcia, who signed as a free agent in 2018, is the youngest catcher of the group. He posted a .750 OPS with 11 doubles and two triples in the Dominican Summer League last year.

A few notable prospects left off the roster include right-handers Luis Frías, J.B. Bukauskas, Jon Duplantier and first baseman/outfielder Seth Beer. All four players were part of the 60-man roster this season. Bukauskas and Beer were the headline pieces of the Zack Grienke trade to the Houston Astros at the deadline in 2019.

Overall, the D-backs’ instructional league roster is filled with top prospects and intriguing names to examine. Without the AFL, the 2020 season will end in sheer disappointment. But instruct leagues can bring some optimism to an unprecedented year for Minor League Baseball.
