CINCINNATI -- Melvin Mora's left foot remained noticeably swollen on Wednesday afternoon and the D-backs' third baseman was kept out of the starting lineup for a second consecutive game.
Mora said he jammed his foot into the first base bag during Saturday's loss to the Giants, resulting in an injury to a ligament. D-backs manager Kirk Gibson indicated earlier that the injury had occurred on Sunday.
Although the area around Mora's left ankle was still swollen, he said it felt better on Wednesday. X-rays taken on Tuesday were negative.
"I never play 100 percent," Mora said. "Nobody in this game plays 100 percent. I'll be fine tomorrow, maybe the next day. It's not DL stuff."
Ryan Roberts, who hit two home runs in Tuesday night's win, started at third base in place of Mora for the second straight game. Mora is batting .281 in 11 games.
"We'll let Melvin feel a little bit better before we get him back in the lineup," Gibson said. "We'll see what happens with him and plan accordingly."
Roberts shines in Mora's absence
CINCINNATI -- Manager Kirk Gibson largely credited Melvin Mora for the D-backs' victory on Tuesday night. Why? Because he didn't play, and Ryan Roberts did.
"I told [Mora] after the game he was the MVP," Gibson said. "He agreed."
Roberts was a late addition to Tuesday's starting lineup after Mora was scratched due to a jammed left foot. Roberts responded by going 2-for-3 with two homers and three RBIs. It was Roberts' second career multi-home run game.
"He had a great game last night," Gibson said. "Certainly a good option with Melvin out of the order. Ryno is a good player for us. Hopefully we'll keep him going that way."
Tuesday's game was the latest example of Roberts making the most of his opportunities, beginning with the injury to Geoff Blum which helped him earn a spot on the roster out of Spring Training.
Roberts, who is batting .382 (13-for-34) through 12 games with four homers and 10 RBI, refused to speculate on what might have been or what might occur in the future.
"I just think about trying to play every day, do my best and get my work in," Roberts said. "I don't think about what ifs or the past."
Gibson very high on reliever Hernandez
CINCINNATI -- D-backs manager Kirk Gibson said the best of right-handed relief pitcher David Hernandez is yet to come.
Hernandez allowed an unearned run in the eighth inning of Tuesday night's victory, ending his streak of seven consecutive scoreless appearances to begin the season. He retired the next three batters in the eighth to maintain the D-backs' one-run lead, including a strikeout of Reds first baseman Joey Votto, who's batting .407.
Hernandez was acquired from Baltimore in December in the trade that sent Mark Reynolds to the Orioles.
"He's got a great arm," Gibson said. "Plus-plus velocity. We haven't seen his breaking ball as much as the reports show. He comes right at you."
Hernandez, who has six strikeouts and five walks in 8 1/3 innings, has a solid repertoire of pitches. Gibson said it's the little things, the fine nuances of the game that will come last for the 25-year-old.
"Holding runners, getting the signs properly," Gibson said. "When to hold or throw over, when to step off. It's new to him. A work in progress."
Gibson tweaks lineup against Reds
CINCINNATI -- Manager Kirk Gibson tweaked the D-backs' starting lineup just a bit for Wednesday night's game against the Reds.
Melvin Mora remained out of the lineup for the second consecutive day due to a jammed left foot. Ryan Roberts, the offensive hero with two homers in Tuesday night's win, was back at third base.
Russell Branyan played first. Willie Bloomquist lead off and played left.
Miguel Montero, who's batting .380 in 14 games, was in the No. 8 spot for the second time this season.
"He's a catcher, first and foremost," Gibson said. "We want to keep him fresh. He doesn't get as many ABs down there."
CINCINNATI -- D-backs closer J.J. Putz earned the save in Tuesday night's 5-4 victory in Cincinnati. It was his fourth consecutive save to begin the season, establishing a new franchise record held previously by Mike Morgan, who had three straight saves for the D-backs to begin the 2000 campaign.
"I'm just trying to be efficient and get quick outs," Putz said. "[Catcher Miguel Montero] has done a great job, for not knowing me very well. [He] didn't get a chance to work with me that much in the spring. He's been mixing up pitches back there. He's definitely the leader on the field."
Putz has a 1.29 ERA with no walks and nine strikeouts in seven innings pitched. He allowed one earned run and four hits in his first six appearances.
