Wandy Rodriguez hasn't been awful in his first three starts with the Pirates. However, he also hasn't provided the lift Pittsburgh was seeking when it traded three prospects to the Houston Astros for the left-hander on July 24.

Rodriguez is now 0-2 in three starts since the trade after taking the loss Thursday as the Arizona Diamondbacks beat the Pirates 6-3 to split a four-game series in Pittsburgh. Rodriguez gave up four runs and seven hits in six innings, walking two and striking out two.

Rodriguez's ERA is now 4.74 as a Pirate. In 19 innings, he has allowed 10 runs on 20 hits while walking seven and striking out 11.

The 33-year-old veteran was 7-9 with a 3.79 ERA in 21 starts for the Astros.

Rodriguez hasn't pitched appreciably better than the man he replaced in the rotation, right-hander Kevin Correia. After winning a spot start against Arizona on Wednesday night, Correia is 9-6 with a 4.49 ERA in 21 games, 20 starts. He has also won seven straight decisions, the longest active streak in the National League.
