Tuivailala was trying to chase down Rougned Odor in a rundown between home and third. He tossed the ball to catcher Mike Zunino, then fell to the ground and wasn’t putting any weight on his leg as he was helped off the field.
The Mariners eventually got the out but lost the game 11-7.
Seattle acquired the right-hander from the St. Louis Cardinals in a trade on July 27. In five games with the Mariners, he has allowed one run and six hits in 5 1/3 innings.
