Freddy Garcia, 36, was 19-14 with a 4.29 ERA over the past two seasons with the Yankees, averaging 127 innings a season. Garcia pitched well in a hitter friendly stadium, in the toughest offensive division in baseball. I'd expect the ERA to go down about 3/4's of a run next season. If he makes the ball club, he would probably be the 5th starter. Garcia has spent his entire career (excluding a dreadful 11 starts for the 2007 Phillies) in the American League, so a switch to the NL will help as well. This is a very smart, no risk, very high reward signing.
Tim Stauffer, 30, missed most of last season due to shoulder issues. He has been plagued by injuries for his entire career. He was 9-12 with a 3.73 ERA for the 2011 Padres, and was looking to build on it in 2012, but was injured. He is expected to be ready at the end of April. If Stauffer can stay healthy, he will be an excellent addition to the pitching staff.
I do have bad news, it appears Jason Marquis and Freddy Garcia were the two starting pitchers who Josh Byrnes mentioned at the start of the offseason. There is still a small chance you see a trade in spring training, and a smaller chance you see a big trade in spring training.
