Although the D-backs pursued Loretta strongly, his agent, Bob Garber, said that the Dodgers' offer was better.
That means the D-backs will continue their search for a second baseman to replace Orlando Hudson, who is expected to receive a lucrative offer to sign elsewhere.
The D-backs made a one-year offer plus a club option to infielder Ramon Vazquez last month, but at the time, Vazquez's agent, Melvin Roman, said his client had received at least one offer that was better.
So now the D-backs will wait to let the market for infielders sort itself out, confident that someone in the group of Vazquez, Damion Easley, Nick Punto and Felipe Lopez will fall to them, or that they can acquire one through trade.
One player they had inquired about, Adam Kennedy, appears to be staying in St. Louis.
The D-backs would like to re-sign infielder Augie Ojeda, who is eligible for salary arbitration, and they see him as a viable option to at least platoon at second.
