Not only that, but before that there was a pop up Beltre was ready for and Andrus got close so Beltre swung his glove at Elvis' head then stared him down after he caught it. I love watching Beltre interact with his teammates.
Eh not often but it does happen a few times a year. I'd just say it was a factor of knowing they were going to lose. You just can't go down by that much with two of your best offensive players injured.
according to espn rangers blog, murphy was the 6th position player to pitch in rangers history, the most notorious being jose canseco blowing out his arm chucking dozens of knuckleballs warming up in the bullpen.
this happens to, as mentioned before, save the bullpen (rangers play 20 games in 20 days starting this game). also, it happens in games that are out of hand (rangers losing 17-5 when murphy came in, 17-3 when he was warming up).
that said, he has an e.r.a. or zero, w.h.i.p. of one, and k/9 of 9!
