Here are the Rangers' 2021 Top 30 prospects

After making the playoffs five times in the previous seven years, the Rangers are riding a streak of four consecutive losing seasons and coming off an American League-worst .367 winning percentage, their worst since 1985. They brought in Chris Young as GM in December to work under president of baseball operations Jon Daniels as the franchise enters full rebuilding mode.

Three of Texas' best prospects -- catcher Sam Huff, outfielder Leody Taveras and shortstop Anderson Tejeda -- made encouraging if brief big league debuts in 2020. Right-hander Dane Dunning might be the big league team's best starter this year and third baseman Josh Jung could crack the lineup by midseason. But the farm system is unlikely to spark a swift turnaround because many of its top talents are at least a couple of years away from being ready to contribute at Globe Life Field.

The Rangers built their postseason clubs by gambling on high-ceiling prospects who turned into big leaguers or trade fodder. But after having few homegrown success stories since drafting Joey Gallo in 2012's supplemental first round, they've shifted philosophies and many of their highest-profile amateur acquisitions the last two years have stood out for their relative polish. That group includes third basemen Jung and Davis Wendzel and second baseman Justin Foscue from the Draft; Dunning as part of the Lance Lynn trade in December; and shortstop Maximo Acosta and outfielder Yeison Morrobel from the international market.

Following their selection of Foscue at No. 14 overall last June, Texas selected four straight high schoolers: outfielder Evan Carter, right-hander Tekoah Roby, left-hander Dylan MacLean and shortstop Thomas Saggese. While most teams didn't regard that group as highly as the Rangers did, the club believes strongly in its evaluations and was encouraged by how the youngsters performed in instructional league.

Here's a look at the Rangers' top prospects:

1. Josh Jung, 3B (MLB No. 63)
2. Sam Huff, C (No. 78)
3. Dane Dunning, RHP (No. 91)
4. Leody Taveras, OF
5. Cole Winn, RHP
