The Arizona Fall League – where major-league teams send some prospects for additional experience -- recently ended.

Minnesota had seven players in the AFL in 2022. Twins prospects were on the Glendale Desert Dogs along with those from the Brewers, Dodgers, Reds and White Sox.

Glendale finished in second place with a 15-13 record, which put the Desert Dogs in the AFL championship game against Surprise, although the Saguaros won 7-6 in 11 innings.

Here’s a look at how those seven Minnesota players fared.


A 33rd-round pick by Minnesota in 2018, Bentley, a reliever, pitched for Single-A Cedar Rapids (3.06 ERA, 1.02 WHIP, 26 K in 17 2/3 IP) and Double-A Wichita (3.79, 1.53, 47 in 38 IP) this past season. In eight appearances with Glendale, he allowed four runs on seven hits in 11 1/3 innings with 14 walks and nine strikeouts. His WHIP was high, thanks to those walks, at 1.85, but his 3.18 ERA was fifth best on the team.


Taken in the 29th round by the Twins in 2019, Isola is a catcher mainly in name only. With Wichita this past season he appeared in 18 games behind the plate (17 starts) with 17 at first base and 23 at designated hitter. As a catcher, he threw out just one of 39 attempted base stealers. However, he did slash .286/.377/.471 with 10 home runs in 58 games for the Wind Surge. Isola played in 16 games for Glendale, making 12 starts at first and three at catcher. While he threw out 1 of 2 attempted base stealers, he hit just .228/.343/.316 with no homers in 67 plate appearances.


Julien was one of Minnesota’s standout prospects this season. In 113 games with Double-A Wichita he hit .300/.441/.490 with 17 homers and 19 stolen bases. Julien didn’t slow down in the AFL. Julien not only led the AFL in on-base percentage (.563), but it’s also the third-highest mark in league history. He also tied for the lead in batting average (.400) and was second in home runs (5). Julien slugged .686. Little wonder he was named an AFL All-Star and the AFL Breakout Player of the Year.


In his first full year in Minnesota’s system after coming over to the Twins in a 2021 deadline deal with Toronto, Martin struggled at Wichita, batting .241/.367/.316 as injuries held him to just 90 games with the Wind Surge. With Glendale, he was an AFL All-Star. Playing mostly shortstop (12 starts, with five starts in center field), Martin, selected No. 5 overall by the Blue Jays in 2020, slashed .374/.454/.482 with six doubles, a homer (he had just two with Wichita) and 10 stolen bases (with just one caught).


Olsen, a 19th-round pick in 2018, didn’t begin pitching in the Twins organization until 2021 due to multiple injuries and surgeries plus the canceled 2020 minor-league season due to COVID-19. In 16 games, with three starts, for Cedar Rapids this year he had a 4.76 ERA, 1.32 WHIP and 30 strikeouts in 22 2/3 innings. Olsen appeared in five games for Glendale, with four starts, allowing eight runs on 15 hits in 13 2/3 innings (5.27 ERA) with 10 walks and 17 strikeouts, the latter was the third most on the Desert Dogs.


Peguero came over from Cincinnati’s in the Twins’ offseason trade for Sonny Gray. He made just 17 relief appearances for Wichita in 2022, allowing 11 runs in 18 2/3 innings. He was, however, an AFL All-Star. In nine relief appearance with the Desert Dogs, Peguero allowed seven runs (three earned) in 11 innings, giving up 10 hits and eight walks with nine strikeouts. The walks were out of character, as Peguero owns a 1.7/per 9 walk rate in the minors over his career.


A 16th-round pick in 2019, Shreve posted a 3.08 ERA, and 1.158 WHIP with 39 strikeouts in 38 innings for Cedar Rapids. He made nine relief appearances for Glendale, spanning 14 2/3 innings, and finished with the second-lowest ERA (1.84) and WHIP (1.02) on the team. He also fanned 12.
