The Arizona Diamondbacks promoted third base prospect Matt Davidson from Class AAA Reno on Sunday, one of several moves by the club.
Davidson, who was the No. 35 overall pick in the 2009 draft, has an .832 OPS with 16 home runs and 68 in 108 games at Reno.
The 22-year-old was the MVP of the Futures Game at Citi Field in New York during the All-Star break. He entered the season as a top 100 prospect by several publications, including Baseball America.
Davidson will likely play regularly at third base while Martin Prado moves over second base and the outfield.
Veteran infielder Eric Chavez was placed on the 15-day disabled list with hip and knee injuries. The move was retroactive to Saturday.
The club also demoted right-handed reliever David Hernandez to Reno and recalled lefty reliever Eury De La Rosa. Hernandez is 4-6 with a 5.59 ERA in 48 1/3 innings. De La Rosa threw 2 1/3 scoreless innings in a previously stint with Arizona.
