Only seven pitchers in MLB pitched more than 20 innings and gave up zero home runs. Three of them were on the Giants:

Matt Gage, 25 1/3rd innings, no HRs.
J. T. Brubaker, 28 2/3rds innings (12 with the Giants, rest with Yankees), no HRs

and...

Stanford alum Erik Miller, the guy who strikes out Shohei Ohtani at will. 30 innings, 0 HRs. 20 walks, unfortunately, that will need to come down.

Giants as a staff gave up the fewest HRs in MLB with 143. Webb led the league in IP (207), hits (210), strikeouts (224). Interestingly, All-Star Robbie Ray led the league in walks with 73.

re: only giving up 143 HRs, it helps to play 81 games at Oracle.

Baseball Savant says Oracle is tied with Mariners Park as the most difficult overall park in which to hit over the last three years, but just #17 this year. #22 in HRs
