Just when you start thinking the injuries will stop, they just get worse.
to be fair, there is no indication as to exactly what caused Matt Harrison to be pulled from his rehab start this evening for AAA Round Rock. All we know is that he came out for the 4th inning and experienced numbness in his pitching hand. He'll be examined further in Arlington, but it certainly doesn't sound great.
Hopefully, it's something minor, but when you're talking about a guy that is coming off of two back surgeries, it's definitely cause for concern. Chances are, we'll know more in the next few days.
