Szapucki was recalled by the Giants on Friday.
Szapucki's lone big-league appearance of the season came against the Giants back in late May, prior to his deadline-day move from the Mets. His current employers knocked him around for nine runs in just 1.1 innings in that appearance, but he's been far better at the Triple-A level, posting a 3.38 ERA. Yunior Marte was optioned to clear space in the bullpen.
