Roy Oswalt has been one of the Houston Astros most reliable arms since he was called up to the majors in 2001. Here is an Astros baseball cap game worn by the steady pitcher and showing excellent use. The cap has an Authentic Diamond Collection tag, a New Era tag, and a 7 3/8 size tag stitched along the back of the sweatband. There is also 59Fifty seam tape inside. Oswalt's #44 is written inside the front of the cap. The cap is faded, has sweat stains on the sweat band and has dirt on the underside of the bill.
