MILWAUKEE (AP) — Another day, another set of milestone accomplishments from Major League Baseball’s rookie class of Jacksons.

San Diego’s Jackson Merrill went 3 for 5 and drove in two runs and Milwaukee’s Jackson Chourio hit a two-run homer and scored twice in the Padres’ 7-3 victory over the Brewers on Monday night. Both players are just 20 years old, though Merrill turns 21 on Friday.

According to Sarah Langs of MLB.com, this was only the fourth time since RBIs became an official stat in 1920 that two players under 21 had produced multiple hits and multiple RBIs in the same game. The last time it happened was in 1965, with Boston’s Tony Conigliaro and Tony Horton.

The other instances came in 1955 (the Washington Senators’ Harmon Killebrew and the Kansas City Athletics’ Clete Boyer) and 1959 (Cincinnati’s Vada Pinson and the Los Angeles Dodgers’ Ron Fairly).
