KANSAS CITY, Mo. -- The Royals traded third baseman Emmanuel Rivera to the Arizona Diamondbacks for right-hander Luke Weaver in the second minor move made by Kansas City on Monday to add organizational pitching depth.
The 26-year-old Rivera was hitting .237 with six homers and 22 RBI in 63 games for the Royals this season. But he was mostly used as a backup in Kansas City, and his trade could mean a move back to third base for elite youngster Bobby Witt Jr. and more time in the lineup at shortstop for rookie Maikel Garcia.
Weaver is 1-1 with a 7.71 ERA for Arizona this season. He has a 4.76 ERA across parts of seven big league seasons.
The Royals figure to be prominent dealers ahead of Tuesday's trade deadline. Two-time All-Star utilityman Whit Merrifield and relievers Josh Staumont and Scott Barlow are among the most likely to be dealt.
