Saturday, 7:05 PM – Armando Galarraga
Galarraga is making his first big league appearance of 2012, after struggling through nine starts at Triple-A. He has a very hittable fastball that sits around 89-92 MPH and has occasionally touched 94. His 89-91 MPH sinker has limited movement and does not generate many ground balls. Galarraga’s best pitch is his 84-87 MPH slider, which he has historically gone to on more than a third of his pitches. He also throws an 82-86 MPH changeup. Galarraga’s slider is a solid pitch, with a whiff rate right around league average. None of his other offerings are all that effective, as they rarely miss bats and often lead to hard contact. Galarraga has not pitched in the majors since May 2011, so it is possible that his approach has changed a bit since we last saw him.
