Sam Selman made an appearance out of the Giants' bullpen at Fenway Park on Tuesday night, and over the past couple of months, he also has pitched at Oracle Park and Dodger Stadium, along with getting his MLB debut out of the way. But Selman's most pressure-packed moment this year might have come in a cramped batting cage a few miles from Seattle. Selman took part in a pro day at the Driveline Baseball facility and signed with the Giants a couple of days later.
