PHOENIX -- Third baseman Mark Reynolds was back in the D-backs starting lineup Sunday for the first time since exiting Wednesday's game due to dizziness.

Reynolds underwent neurological exams each day since being struck in the helmet by a 95-mph Collin Balester fastball in Tuesday's game against the Washington Nationals.

"We're confident that he'll be fine," interim manager Kirk Gibson said Sunday morning. "I'll be really sure to make sure that he's feeling fine as the game goes on, and keep an eye on him. If he isn't, we'll get him out of there."

Reynolds, who was available to pinch-hit and play defense Saturday, camped out in Gibson's office following the 6-5 win, hoping to convince his skipper that he was ready.

Reynolds (.220, 25 home runs, 69 RBIs) hit sixth and manned the hot corner.

Gutierrez throws again en route to return

PHOENIX -- Juan Gutierrez is on his way back.

The D-backs right-handed reliever, who was placed on the 15-day disabled list Tuesday because of inflammation in his throwing shoulder, played catch for the first time Saturday and a second time before Sunday's series finale with the San Diego Padres.

"I feel so much better," Gutierrez said. "The soreness has been going down pretty good."

Gutierrez added that he will long toss Monday in Milwaukee, where the D-backs begin a three-game set with the Brewers on Monday, then throw in the bullpen Tuesday. He would need at least two more bullpen sessions before pitching in either a simulated game or a brief Minor League rehab assignment before returning.

Gutierrez, who reported his shoulder problem during Arizona's series in New York last week, last pitched against the Nationals on Monday.

As skipper Kirk Gibson's closer of choice lately, he had pitched comparatively well, lowering his ERA from 10.31 on June 1, to 6.69 on Aug. 2. He also converted both of his save opportunities in July.

Rodriguez struggles in D-backs debut

PHOENIX -- Right-handed reliever Rafael Rodriguez waited four days for his Arizona Diamondbacks debut.

It wasn't worth the wait.

Rodriguez, one of four pitchers acquired from the Angels for Dan Haren on July 23, was recalled from Triple-A Reno on Wednesday and on Sunday allowed two runs in two innings of work in the D-backs' 10-1 defeat to the Padres.

Not the best first impression for his new club.

"I haven't pitched for five or six days, but I felt good," said Rodriguez, who actually hadn't appeared in a game since Monday at Triple-A Reno. "Sometimes I'm a little wild, but you have to locate."

Which was why Sunday's performance was especially frustrating: Rodriguez said he did locate.

But after tossing a scoreless eighth, he allowed a Jerry Hairston single to lead off the ninth, and then the big blow: Chris Denorfia's two-run home run into the left-field seats.

"Sometimes, you make a good a pitch," he said, with an ice pack draped over his throwing shoulder, "and they make a good hit."

Rodriguez will get another chance to prove his worth, perhaps as soon as this week in Milwaukee -- the D-backs open a four-game set with the Brewers on Monday.

"The chance is right there," said Rodriguez, who broke into the big leagues at age 24 with the Angels in 2009 and pitched 18 games that season. "I just have to show what I got."

Scoring change erases Crosby's error

PHOENIX -- Chase Field official scorer Rodney Johnson announced Sunday morning a scoring change on a seventh-inning play in Saturday's game.

What was originally ruled a Bobby Crosby fielding error -- his second in as many starts -- became a single for the Padres' Miguel Tejada. Tejada didn't score in the inning, so ERAs remain unchanged.

As a result, San Diego collected 12, not 11, hits in the game, and Crosby's D-backs committed one, not two, errors.

Worth noting

Reliever Aaron Heilman, who pitched his fourth consecutive game and allowed two ninth-inning home runs Saturday, was unavailable to pitch on Sunday. ... Interim manager Kirk Gibson discussed pitcher Brandon Webb, who hasn't been active since Opening Day 2009, outlining his own rehab assignment. "In my opinion, that's the kind of thing that's up to him. He deserves it," Gibson said. "He pitched a lot innings, won 22 games for us [in '08], and he wasn't feeling good when he won the 22 games; and we knew that." ... Fifteen current D-backs players are alumni of the Arizona Fall League, which kicks off on Oct. 12. Arizona will send a few of its top prospects -- perhaps even rehabbing pitcher Jarrod Parker -- to baseball's "finishing school."
