"I think it's still somewhat early," Towers said Wednesday. "We're not looking to sell. We're five games out of the Wild Card and there are two teams that are going to get in this year. I look at the National League as a whole -- if we get on a little run we can get right back in this thing. If we go through this another month, then it might be different the first part of July."
If the D-backs were to fall further out of the race before the Deadline, it's possible they could look to deal veteran left-hander Joe Saunders, who is a free agent and is not expected to re-sign with the club because of all the young near-Major League pitching talent.
Closer J.J. Putz is another possibility. The D-backs hold a $6.5 million club option on him for 2013. It includes a $1.5 million buyout, and he could be attractive to contenders.
Of course, the D-backs still plan on being contenders right up until the end.
That being said, Towers continues to work the phones.
"I'm always looking at trades, regardless of we're winning or losing or where we're at," he said. "I'm looking not only in the near future, but long term as well. I've already kicked some tires on some things. I'm not saying anything is close, but you're always looking, always keeping an eye on down below where your depth is."
