PHOENIX -- The D-backs conclude a stretch of 30 games in 31 days on Sunday, the longest such streak they have throughout their 2012 schedule. Playing so many innings in so few days, it's not surprising to see a few miscues on the field. But the club committed nine errors in its last six games, and manager Kirk Gibson is becoming tired of the team beating itself. "We have to play a cleaner game," he said. "There is a bit of fatigue, so there are going to be mistakes. We're trying not to, and we moved on very quickly. It's very frustrating for everybody, but we move on and get back after it. We've lost some tough games."
One of those disappointing defeats came Saturday, when the D-backs made three errors, including two in the Nationals' five-run fifth inning that was the difference in the outcome. "I was in the elevator with some people and everybody talked about how the Nationals beat us, I just thought we beat ourselves," Gibson said. "They are a good team and you can't do that to them. I got up early this morning thinking about it. Guys are busting their tails and the schedule is probably getting to us right now." One of the errors the D-backs made on Saturday came on a misplayed ground ball to Chris Johnson at third base. Since joining the team on July 30, Johnson has raked at the plate but he's also made three errors. "He can be better defensively, he's spent a couple days with [third-base coach Matt Williams] working," Gibson said. "He tends to get the ball close to his body instead of out where he can see it. You lose your view of it. You want to keep your eyes on it and go get the ball. Watch [Nationals third baseman] Ryan Zimmerman, he's really good. That first step is important."
