KANSAS CITY – Prior to tonight’s series opener at Kansas City, the Chicago White Sox purchased the contract of second baseman Nick Madrigal from the Schaumburg training facility and designated right-handed pitcher Kelvin Herrera for assignment. 

Madrigal, 23, entered the season rated by MLB.com and Baseball America as the No. 4 prospect in the White Sox organization. He also is ranked by MLB.com as the No. 2 second-base and No. 40 overall prospect in baseball, and by Baseball America as the Best Hitter for Average and Best Defensive Infielder in the Sox system.

Madrigal, 5-foot-8 and 175 pounds, batted a combined .311/.377/.414 (147-473) with 27 doubles, five triples, four home runs, 55 RBI, 76 runs scored, 44 walks and 35 stolen bases over 120 games between Class A Winston-Salem, Class AA Birmingham and Class AAA Charlotte in 2019. He won the Rawlings Minor League Gold Glove® for second base, was named the Best Defensive second baseman in the Southern League, earned Carolina League midseason All-Star honors and played for the U.S. Team at the All-Star Futures Game in Cleveland. Madrigal also was named Chicago’s Minor League co-Player of the Month for June.

The Elk Grove, Calif. native struck out just 16 times in 532 plate appearances in 2019. He fanned more than once in a game just twice over 120 contests.

Madrigal is a career .309 (194-628) hitter with 34 doubles, five triples, four home runs, 71 RBI, 51 walks, 43 stolen bases and just 21 strikeouts in 163 games over two seasons in the Sox minor-league system. He has committed just five errors in 663 total chances. Madrigal was selected by the White Sox in the first round (No. 4 overall) of the June 2018 First-Year Player Draft out of Oregon State University. 

Madrigal has no major-league experience and will wear uniform No. 1.

Herrera, 30, made two appearances with the White Sox this season (4 ER/2.1 IP), his second with the club after signing as a free agent on January 8, 2019.

Following the moves, the White Sox 40-man roster remains at 40.
