The Royals acquired Luis Mendoza from the Rangers for cash considerations, according to a team press release. The 26-year-old right-hander pitched 111.1 innings for Triple A Oklahoma City last year, posting a 4.53 ERA with 6.3 K/9 and 4.0 BB/9. He got roughed up in his lone big league appearance last season, when he allowed four earned runs in one innings for the Rangers.
Mendoza was out of options, which meant the Rangers couldn't have assigned him to the minors without passing him through waivers first. The Royals placed Mendoza on their 40-man roster, which is now full.
