NEW YORK -- This isn't the way the Mets hoped to start a crucial 10-game homestand.

After allowing a leadoff homer to Shin-Soo Choo, left-hander Jon Niese exited after recording just one out against the Rangers on Friday night -- an eventual 6-5 win -- when a comebacker off the bat of Alex Rios caught him on the side. Niese recovered to record the out, but after a visit from a team trainer and manager Terry Collins, the call was made to the bullpen.

"You've done this before with such an injury, and you've re-injured something else," manager Terry Collins said he told Niese. "You can't go out there until we make sure you don't have a broken rib. We can't have you have a punctured lung. So I just said, 'Jon, I can't let you continue.'

"That's one of the things I like about Jon Niese. He's really become that tremendous competitor."

Right-hander Carlos Torres was the first reliever to get the call, and he posted 4 2/3 innings of two-run baseball.

"Not much to say other than I'm fine," said Niese. "I felt like I was cheated there a little bit. I knew it was just a bruise, and ... I wanted to stay in there.

"Carlos did a great job coming in and shutting [them] down. Everybody else coming in ... It's fun to watch."

Niese has now allowed no more than three earned runs in each of his 17 starts this season.
