More than that, though, Black said he has been impressed with the improvements Bass has made since he first appeared in the big leagues with the team last season.
"It's more than a tick better. ... I would say he's much improved in a lot of areas," Black said.
Bass used a three-pitch mix -- fastball, slider and changeup -- to tie the Giants' hitters in knots as he took a perfect game into the sixth inning. Tim Lincecum broke up the no-no with a two-out single. The Giants then scored twice in the seventh inning on their way to a 2-1 victory.
Bass allowed two runs on six hits with no walks as he tossed a career-high eight innings and also set a new career best with eight strikeouts.
"He's evolved from throwing to a pitcher," said Padres catcher Nick Hundley. "He was a guy who first would rear back and throw it to a pitcher, a guy who is using all of his pitches. He's quickly improving."
Last season, Bass made three starts and had a total of 27 appearances in two stints with the team, as he posted a 1.68 ERA. This season, he has a 2.30 ERA in six games, including four starts since he moved into the starting rotation earlier this month.
"He's quieted down his delivery and that's helped him make more consistent pitches," Black said. "It's just a maturation process and he's learning it on the job."
In a combined 75 2/3 innings in his short Major League career, Bass has a 1.90 ERA in 33 games, seven of which have been starts. He's allowed 59 hits and 31 walks and has 51 strikeouts in that span.
