The Diamondbacks are the only NL West team that has not shown interest in Marlins right-hander Ricky Nolasco.
The D-Backs are not interested in renting a potential free agent and if they acquire a starting pitcher, they will want him to be a significant upgrade over their major league-ready prospects, sources say.
Two starters, in particular, interest the D-Backs, according to sources. One, Brewers right-hander Yovani Gallardo, is available. The other, Cubs right-hander Jeff Samardzija, only could be had for an overwhelming package and the two clubs have not engaged in discussions, sources say.
The Diamondbacks entered Thursday ranked 11th in the NL with a 4.17 rotation ERA. Their best pitcher, left-hander Patrick Corbin, is in his first full season. The addition of a top-of-the-rotation starter would significantly enhance the teams chances in the hotly contested NL West.
The D-Backs, though, arent prepared to move on any pitcher just yet.
They are waiting to see if rig...
