Adams, 32, appeared in 22 games with the Rox but was deployed largely as a pinch-hitter. He’s posted a .167/.250/.194 batting line in 40 plate appearances this season and had accumulated just five plate appearances since coming off the injured list 17 days ago.
Adams slugged 20 home runs with the 2019 Nationals but did so with a .226 batting average and a .276 on-base percentage. His last season of above-average overall production came back in 2018, when he slashed .239/.309/.477 with a career-high 21 homers. Overall, Adams is a .258/.306/.463 hitter in more than 2,600 major-league plate appearances. Nearly all the damage he’s done has come against right-handed pitching, as lefties have carved him up to the tune of a .210/.241/.378 slash line.
Ruiz, 27, was a waiver pickup out of the Orioles organization in late May. Baltimore designated him for assignment after he’d struggled to a .220/.292/.380 batting line across multiple auditions from 2019-21. While he obviously wasn’t able to establish himself with the O’s, Ruiz has batted .314/.375/.523 (118 wRC+) in a hitter-friendly Albuquerque setting. The Rockies are surely encouraged by a tiny 14.1 percent strikeout rate in that time and will give him a look.
Adams’ release figures to be the first of multiple personnel changes on the Rockies’ roster this week. Colorado is widely expected to trade away some impending free agents, with Jon Gray, Trevor Story, Mychal Givens, C.J. Cron and Daniel Bard among the possible trade candidates on the roster.
