Acuna was added to the Rangers' 40-man roster Tuesday, Jeff Wilson of RangersToday.com reports.
One of Ronald Acuna's younger brothers, Luisangel hit .278/.367/.425 with a 23.6 percent strikeout rate, 11 home runs and 40 stolen bases in 91 games across High-A and Double-A as a 20-year-old. At roughly 5-foot-8, he lacks his big brother's power potential and physicality, but Acuna is still ahead of schedule on his ascent up the organizational ladder.
