Diaz went 1-for-1 with a double, an RBI and a run scored in Wednesday's 6-4 extra-inning win over the Royals.
Diaz entered the game in the eighth inning after starter Kyle Higashioka was removed for a pinch runner and played a vital role in the win. He went the other way on a 3-2 pitch low and away in the zone to drive in the game-winning run before scoring the insurance run. He also threw out a would-be base stealer in the eighth. Diaz was recently signed by the Rangers when the club placed Danny Jansen (forearm) on the 10-day injured list. He's appeared in two games since joining the organization while serving as the backup to Higashioka.
