In big blow to bullpen, Reynolds shut down for six weeks

LOS ANGELES -- An MRI taken of Matt Reynolds' ailing left elbow revealed a slight tear in the ulnar collateral ligament and he will be shut down for the next six weeks.

After that the D-backs reliever will begin a throwing program. Reynolds is also expected to get a second opinion in the coming days.

D-backs manager Kirk Gibson said the injury is similar to the one suffered by shortstop Didi Gregorius over the winter. Gregorius was shut down after his injury and once he resumed throwing in Spring Training, he felt fine and experienced no setbacks.

Reynolds had been one of the D-backs most consistent relievers this year before injuring his elbow. He was placed on the 15-day disabled list Monday and left-hander Joe Paterson was called up from Triple-A Reno to take his place on the roster.

"Injuries can never be an excuse for us," Gibson said. "It's a blow. There's other guys that are prepared for the opportunity to be part of the team in this capacity and it opens up that avenue for them. We need to get him back healthy and hopefully he can come back and contribute before this year gets over."

Reynolds, who was acquired from the Rockies during the offseason, had a 1.98 ERA and two saves in 30 appearances this year.

For rookie reliever Brewer, a doubly special night

LOS ANGELES -- When he tossed 1 2/3 innings of relief Monday night, D-backs right-hander Charles Brewer became the first player to be born in the state of Arizona to make his Major League debut with the D-backs.

"I can't think of anything else in my life that I would take pride in more than that," Brewer said. "Just thinking about all the kids in Arizona right now in Little League and playing travel ball and high school ball, I was just another one of those kids and those kids can do the same thing. Hopefully that will be an inspiration to them."

Brewer played collegiately at UCLA, so he was excited to be able to make his big league debut at Dodger Stadium.

"Besides being back in Phoenix in my hometown, being in LA for my debut was pretty awesome," he said. "The atmosphere of the stadium was crazy and my family was here, so it was awesome."

Brewer almost got his career off to a rocky start when his first pitch was laced to right field by Tim Federowicz.

Outfielder Gerardo Parra, however, made a leaping catch as he crashed into the right-field wall to rob Federowicz of an extra-base hit.

"I got scared there for a second, I really did," Brewer said. "I was like, 'This can't happen on my first pitch, c'mon.' But how about G's play out there? That was ridiculous. That was an unbelievable play by him."

Snake bites

• Injured second baseman Aaron Hill appeared in his first game since being placed on the disabled list April 15 with a fracture in his left hand. Hill got three hits in four plate appearances while playing in an intrasquad game during extended spring training on Tuesday.

"Everything felt good today," Hill said.

Hill is scheduled to hit again in an intrasquad game Wednesday before taking Thursday off.

"If he doesn't have any discomfort that he can't deal with, then he's going to proceed forward with it," D-backs manager Kirk Gibson said.

• Closer J.J. Putz, who is on the disabled list with a strained right elbow, threw his second bullpen session Tuesday and is expected to face hitters -- including Hill -- for the first time Friday.

"J.J. threw very well and felt good," Gibson said.

• The D-backs' one-run win Monday was their 15th of the year, most in the Majors. The A's and Padres are tied for second with 13.
