The Texas Rangers made sure to keep their catching depth around a little longer, extending Robinson Chirinos on a one year deal that'll keep him in Texas through 2018 and possibly 2019 with a club option. Chirinos was relegated to the backup role when Texas brought in Jonathan Lucroy last summer, but that may be a role that fits him better going forward, getting occasional starts behind Lucroy.
Chirinos, 32, has struggled with injuries and consistency throughout five years between Texas and Tampa Bay. Chirinos has never played 100 games, and has never hit above .240. He paks a little power, but not enough to balance out his poor hitting. Chirinos is a respectable defensive catcher though and gets on base well meaning he does have value, just not as a starter.
The Rangers have been battered by injuries the last couple years, so having depth won't hurt. There's no doubt that the goal is to win the division and make a playoff run, something that'll be tougher with the young Astros, and the suddenly dangerous Mariners.
Lucroy has been pretty durable throughout his career, but you never know if that will change. Having Chirinos the next couple years gives the Rangers some veteran insurance for the next couple years.
