There are some good starting pitchers on the trade market.
According to Bruce Levine of ESPNChicago.com, Atlanta is one of many teams who has shown interest in Cubs' ace Ryan Dempster. Dempster leads the MLB with an amazing 1.86 ERA, and he extended his scoreless-innings streak to 33 by shutting out the D-Backs in six innings.
Even though Dempster has been dominant, the Cubs have struggled. Dempster will come at a high price, and teams will be willing to give up a lot for the star pitcher. If Atlanta is willing to give up a few good prospects, attaining Dempster could be feasible.
If Dempster goes somewhere else, there's still Zack Greinke. He has been struggling recently, but he is still the ace of the Brewers and still has a 9-3 record. Greinke is a strikeout machine; he has 117 in 116 innings pitched this year.
According to Tom Haudricourt of the Journal Sentinel, Greinke could end up staying in Milwaukee. If the Braves can't land either pitcher, they could pursue D-Backs slugger Justin Upton.
Unlike Greinke, Upton wouldn't be a rental, and he has a lot of power. As Buster Olney of ESPN said, Upton would be a nice fit in Atlanta.
The Braves have a good team, but they would benefit from adding a big-name player. As I mentioned in my article about trade targets for the Braves, Atlanta could target Ryan Cook, who would be a setup man for closer Craig Kimbrel, or starting pitcher Brandon McCarthy.
The Braves probably need to make a move at the trade deadline if they want to contend for a championship.
They have a good core, but they would benefit from adding depth to their rotation and adding another great reliever. I expect them to be major players at the deadline.
