Hi, I am a Giants fan, but I have been thinking about the Diamondbacks team lately. I think they are a good team, but they can be a a lot better. 

To start, I have to say that there are some holes. First and second basemen fourth and or  fifth starter. These holes can be filled though. There are many free agents that can fill the holes.

 So lets start with second base, I think the answer is Felipe Lopez. He is a fantastic hitter, and he played well for you last year. Also he will come cheap and without costing any draft picks. Felipe hits high  obp, avg. gets a lot of hits, and hits good slugging percentage. 

First base can be filled by signing Carlos Delgado. Delgado is a great hitter. He could be signed cheaply. Delgado gets on base, hits homeruns, gets rbis. He is also a great clubhouse guy.Delgado improves hitting and adds another power guy to the lineup. 

Pitching is your strength, why not add to the big three. I would suggest either Vicente Padilla or Erik Bedard.

So if the Diamondbacks signed Felipe Lopez, carlos Delgado, and one of the pitchers, this team could really go far.  The pitching itself would win games, but the great offense really makes them contenders.

So look at the lineup

Stephen Drew

Justin Upton

Felipe Lopez

Mark Reynolds

Conor Jackson

Carlos Delgado

Miguel Montero

Chris Young

pitcher              This lineup has everything except for the fact that there isn't a lot of base stealing.

Rotation

Brandon Webb

Danny Haren

Edwin Jackson

Erik Bedard/Vicente Padilla

Ian Kennedy

closer: Chad Qualls

Bob Howry

Juan gutierrez

Aaron Heilman

Clay Zavada

Blaine Boyer

Esmerling Vasquez

Leo Rosales 

The bullpen is fantastic, probably one of the top bullpens in the Mlb 

With the new additions this team is really good.
