His father, Ruben Sierra, signed with the Rangers in 1982 as a free agent out of Puerto Rico. All high schoolers from Puerto Rico have been subject to the Draft since '90.
Sierra played parts of 10 seasons with the Rangers, becoming an everyday player at the age of 20. His best season came in 1989, when he hit .306 with 29 home runs and drove in 119 runs. Sierra finished second to Robin Yount in the Most Valuable Player balloting that season.
"I don't know what Senior's scouting reports were as a 17-, 18-year-old," Rangers general manager Jon Daniels said, "but [Sierra Jr.] is athletic. We wanted guys with quality upside who can reach [the big leagues]."
Sierra Jr. shares plenty of similarities with his father. He stands an inch taller than his father, at 6-foot-2. Sierra Jr. has played center field throughout high school, but once he adds weight to his 172-pound frame, he may shift to a corner-outfield spot, which is precisely where his father played.

Sierra's best tool may be his blazing speed. Perfect Game USA, an organization that puts together showcases and tournaments across the U.S., reports Sierra Jr. has run a 4.18 40-yard dash and a 6.38 60-yard dash. If reliable, those are incredibly fast times.
"I haven't seen him run, but [those times] wouldn't surprise me," Daniels said.
Sierra Jr. also has a powerful arm, as he has been clocked in the low 90s while throwing from the outfield. As a lefty, he has hit the upper 80s on the mound.
"We felt the strength of the Draft was pitching," Daniels said. "I think that talks to how difficult it is to find young position players, whether it be through the Draft or to sign them."
