I finished a game of RTTS last night and got an alert I just earned a 3rd Inning Boss. Without digging into exactly why, was pretty happy that RTTS play triggers good things now and then.
Chose 97 Glaus. Not that he's going to perform a great deal better than 96 Torre or 85 Machado, but it was an unexpected freebie.
Glaus has been amazing for me so far.
