The Rangers have designated infielder Yadiel Rivera for assignment and selected the contract of left-hander John King from their alternate training site, per a club announcement. They’ve also added lefty Jake Latz to their 60-man player pool and assigned him to their alternate site.
Rivera, 28, appeared in just four games and went 0-for-5 in that brief time. The former Brewers and Marlins utilityman is a career .175/.244/.217 hitter in 319 Major League plate appearances and a .243/.280/.352 hitter in parts of four Triple-A seasons. The Rangers will have a week to put him through waivers or release him.
The 25-year-old King was Texas’ 10th-round pick in 2017 and will be making the jump from Class-A Advanced to the Major Leagues thanks to the lack of a minor league season in 2020. King started 19 games between two Class-A levels last year and was dominant, pitching to a 2.40 ERA with a pristine 91-to-13 K/BB ratio and a huge 57.9 percent ground-ball rate in 97 1/3 innings. On top of that, King induced a whopping 23 infield flies.
