New SF Giants pitching prospect Blade Tidwell completed six strong innings with seven strikeouts in a 4-2 loss to the Round Rock Express. That was his third quality, and it is hard to ignore that the results have followed an interesting change in pitch mix.
When the Giants traded for Tidwell, he led with a mid-90's four-seam fastball, followed by a low-80's sweeper and sinker. Since joining San Francisco, he has led with his sweeper and a power slider, while the four-seamer has taken a backseat.
Tidwell still throws a mid-90's fastball, but he is leaning more on his sinker now.
