Rawlings official MLB baseball (Selig) signed by five members of the Los Angeles Angels including Mike Trout. Unfortunately modern signatures being what they are we cannot identify a single other signature on the ball. We also believe that modern players who sign this way should be ashamed of themselves. Thankfully the gang at James Spence Authentication is well-versed in identifying signatures and were able to identify four of the five signatures on the ball. In addition to Trout they have also identified and authenticated catcher Hank Conger pitcher Michael Kohn and pitcher Kevin Jepsen. The fifth player unfortunately remains unidentified.
