Terry wants reliable defense but fears a firestorm. Daniel Murphy and Ruben Tejada flip positions for Thursday night's series opener against the Arizona Diamondbacks, with Murphy back to handling third base and Tejada at second base. Collins resisted a more radical shuffling by leaving Wilmer Flores at shortstop, even though Tejada at that position represents an even stronger defensive alignment. The manager did not rule out moving Flores to another infield position down the road. However, Collins said he did not want to create a frenzy in the media by making Flores part of the current realignment. Collins added that Tejada's two-error game at third base on Wednesday in San Diego was not a factor in making the switch now. "I'm going to stay away from the shortstop position right now because it's a firestorm," Collins said about Flores' role. "But I know Ruben Tejada should play in the middle of the infield. "And Dan Murphy has proven he can play second base. But I also believe Dan Murphy is as good a third baseman as there is in this league. I've seen it in living color. I've seen this guy's reactions. He's got a strong arm. He's got good hands. He's got good reactions. So I feel very, very comfortable with him at third base. And I think we're better off there. "This was not just something because of what happened yesterday with Ruben. This is something we've been talking about doing for a week. Dan Murphy is one of the best players in baseball. He's a stinkin' All-Star. You just don't take All-Stars and switch their positions for one or two days. With the conversation we had with David the last couple of days, I said, 'This is something that's going to be a little while. So it's time to consider moving Dan back over there to where I think we'll be better and put the other kid back in the middle of the field where he belongs.' "So we'll have this alignment. And I'm not saying it won't switch in the middle. But, right now, this is what we're going to go with."
