[Giants]

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.
