"The Padres completed a major trade Saturday morning that raised as many questions as it answered.

The Padres sent right-handed starting pitcher Mat Latos to the Cincinnati Reds for right-handed starting pitcher Edinson Volquez and three of the Reds' top 10 prospects — first baseman Yonder Alonso, catcher Yasmani Grandal and right-handed relief pitcher Brad Boxberger.

The trade added talent at two of the Padres deepest positions on paper -- first base and catcher -- with Alonso moving ahead of Anthony Rizzo at first and possibly freeing Jesus Guzman for a move to left or right field.

"We're not guaranteeing anything to anyone," Byrnes said after negotiating his biggest trade in his seven weeks as the Padres general manager."
