Steven Geltz was undrafted out of the University of Buffalo but was signed by the LA Angels. 4 years later, he is being called up to the big leagues. Here is a short scouting report on the reliever:
The right-hander brings the ball back behind him and low before firing it over the top. His fastball doesn't look overpowering, but hitters seemed to have some problems catching up to it, perhaps because of the deception. He throws in the low to mid 90s, getting up to 95 MPH. He likes to throw it high and that is where he gets his whiffs. He also has a slider at at about 85-86 with pretty quick drop that he can use to get lefties out.
This is why the Angels brought Geltz up, he has this ability:
In AA this year, Geltz struck out 38.9% of the batters he faced, a crazy number. When he was promoted to AAA, that number dropped significantly but was still above average at 21.5%. His walks jumped from 6.2% to 8.4% (which is still slightly below PCL average). After posting a .87 FIP in AA, his FIP was a good 3.69 and SIERA a respectable 3.94 in the PCL.
I think Geltz can be a serviceable reliever for the Angels this year. Despite the deception, I don't think the delivery opens him up to being easily picked up by lefties. The fastball is good enough and the slider should keep lefties honest. He actually has reverse splits in the minors this year, so it will be interesting to see how the Angels use him.
