I have a baseball with 2 signatures which I cannot identify. It is a batting practice ball and is marked with a large H. I'm assuming this is a Houston Astros ball as they sometimes mark their balls in that way. Although the uniform numbers are included with the signatures, I haven't been able to find a match. Possibly the names are really from another team... like who they might have played that day after batting practice? The ball is Rawlings and is green stamped Official Training Ball with commissioner stamp and mlb logo with 'Practice' underneath. Any help would be greatly appreciated. Thanks!
