Don Orsillo hasn't been calling San Diego Padres game for very long, having spent the last 15 seasons as the voice of the Boston Red Sox on NESN, so it may take him a while to nail down all the in-and-outs of his new gig.

Like, you know, the name of his broadcasting partner.

During the opening segment of Tuesday's broadcast of the Padres' game against the Colorado Rockies, Orsillo mistakenly referred to his partner, Mark Grant, by the name of the another FOX Sports baseball analyst, Mark Sweeney, but the two were able to laugh it off.

Now that's rapport.
