Lago was acquired by the Railroaders from the Sioux Falls Canaries on January 13, 2020 in exchange for infielder Ryan Brett, outfielder KC Huth, and left-handed pitcher Eudis Idrogo. When the Railroaders did not participate in the 2020 American Association season, the Canaries selected Lago with the second overall pick in the league’s dispersal draft, and he put together another excellent season in Sioux Falls. 

The versatile infielder slashed .321/.363/.451 over 58 games for the Canaries, helping the Birds reach the American Association Finals. He rattled off a 10-game hitting streak over the home stretch of the regular season, and smacked three hits in the Finals opener against Milwaukee. All told, Lago’s .321 batting average ranked sixth in the American Association, while his 79 hits and 20 doubles were second. Lago spent most of the 2020 campaign as the Canaries starting first baseman despite having never played the position before as a professional. He committed only five total errors for the season in more than 350 chances across all positions.  

Lago delivered a memorable 2019 season in Sioux Falls, winning the American Association batting crown with a .339 average. In 92 games, the 29-year-old blasted 30 doubles and 13 home runs, driving in 57 runs while adding 14 stolen bases.

Lago joined the American Association in 2018, signing with the Kansas City T-Bones on July 24. He contributed a .283 average over the final 37 regular season contests, then helped power the T-Bones to the championship with a stellar postseason performance. Kansas City traded Lago to Sioux Falls on March 20, 2019 in exchange for the reversionary rights to right-handed pitcher Ryan Fritze.

Prior to signing with the T-Bones, Lago played professionally in his native Cuba from 2010-2015, signing as an international free agent with the Atlanta Braves in 2017. He hit .303 at High-A Florida that season, earning a call-up to Double-A Mississippi the following year.
