SEATTLE - Good news: There may be an explanation for Joey Gallo's recent and dramatic slump.

Bad news: It could be injury-related.

Gallo left Tuesday's 7-2 win over Seattle after the top of the eighth inning with what the Rangers termed as right wrist soreness. He had an X-ray after the game that showed no break, but is expected to undergo an MRI on Wednesday.

Apparently, the wrist issue has been bothering him for a while. He also had some soreness in the area earlier in the season.

"He was really sore," manager Chris Woodward said after the game. "It's been bothering him some. He's so violent with his swing that it puts a lot of torque on the small bones and tendons in that area. You worry about that a little."

Gallo entered the game hitless in his last 14 at-bats, then struck out to ends the first before reaching on a bunt single in the third inning. He then struck out in the fifth inning and popped out in the eighth inning before leaving the game. Gallo has just three hits in 34 at-bats since the All-Star break.
