The Rangers’ decision about selling at the deadline may have been made for them.Joey Gallo, an early season MVP contender and the Rangers’ leader in home runs, walks and on-base percentage, may have to miss up to a month with a hand injury, according to the Dallas Morning News. Gallo left Tuesday’s game in the eighth inning after going 0 for 4 and has been sent back to Texas to be evaluated further.It is unclear exactly what the injury is, but if he has to undergo surgery, which the Morning News suggests he could, the recovery time would be about a month. Related News “It’s not good since we don’t know what exactly is wrong,” manager Chris Woodward said. “He was pretty sore (after Tuesday’s game). He puts a lot of torque on that wrist when he swings.”Woodward said Gallo had been dealing with some soreness over the last week and has just two hits in his last seven games.This could be the second time this season Gallo would miss significant time. He was out for three weeks in June with an oblique injury.Now, this is important not just for the Rangers, who are not entirely out of the wild-card race, but it could also have a profound effect on the trade deadline.Texas is not guaranteed to be a seller, but if their best player is out for a good amount of time, the next move may be to make some trades.
