Lopez will have his contract selected from Triple-A Omaha prior to Tuesday's game against the Rangers.
According to Rustin Dodd of The Athletic, Lopez will immediately step in as the Royals' primary second baseman. The addition of Lopez will move Whit Merrifield to the outfield on a more regular basis, while third baseman Kelvin Gutierrez will likely shift to a bench role as part of the domino effect of the roster shuffle. The promotion is warranted for Lopez, as the well-regarded prospect was slashing .353/.457/.500 with a trio of homers and nine stolen bases through 31 games with Triple-A Omaha this season. Jake Newberry was optioned to Triple-A in a corresponding move.
