First career MLB pitch MLB baseball (not vintage)

[Gary Dunaier]

Interesting thing is that in that game, Montero also got his first ML strikeout (against Derek Jeter). After the strikeout was called the ball was tossed around the infield until it got to David Wright, who realized its significance and had it put aside for Montero.

Don't know if there is a protocol or custom for pitchers' first-pitch-in-the-majors baseballs like there is for players-first-hit-in-the-majors balls. For example, in the case of Matt Harvey's ML debut, the "first pitch" ball was used for at least his first four pitches in the bigs, including his first strikeout. After that first K the catcher either tossed it to one of the players (where it might have been thrown around the infield before being returned to Harvey) or the batboy (in which case the ball was taken out of play and a new one used) - the SNY video footage doesn't indicate which, and I don't believe the broadcasters made any mention of it. (Harvey got his first hit in that game, and the ball definitely was put aside for him.)
