Richard went 2-for-2 with three RBIs in the 9-5 victory over the Mariners on Friday at Petco Park.
Padres manager Bud Black said he hopes to see an offensive surge from his pitchers during the second half of the season.
Richard is 3-for-27 at the plate. Jason Marquis, Saturday's starter against the Mariners, entered the game hitting 2-for-4. Ross Ohlendorf is 0-for-2. Anthony Bass is 4-for-28. Edinson Volquez is 2-for-23.
"We talked about it in Spring Training, how we wanted our pitchers to really be a factor in our offense," Black said. "We still have a lot of baseball left.
"Marquis obviously bolsters it. Ohlendorf, we'll see moving forward. Clayton, I think, is a better hitter than he's shown statistically. Bass is better. The bunting can always improve. Every National League team will tell you that. The hitting can improve no matter what those numbers are."
