Richard, who took the loss Monday against the Brewers, made all 33 of his starts and finished with a career-high 218 2/3 innings. He went 14-14 with a 3.99 ERA, tying his career high for victories from 2010.
"When you look at Clayton individually and what he wanted to accomplish coming back off the surgery, it was to make his starts," said Padres manager Bud Black. "From start to finish, he did his part and held up his part of the bargain."
As for Headley -- who on Tuesday was named the National League Player of the Month for September, the second successive month he's won that award -- he continues to add on to what's been a productive season that has seen him reach career bests in home runs (31) and RBIs (113).
Headley has also proven durable at third base. The game Tuesday was his 160th of the season. Heading into Tuesday, he had played 1,382 innings, trailing Hunter Pence (1,391 1/3), Jose Reyes (1,390 2/3) and Starlin Castro (1,384 2/3).
"He's done it all year, especially in the second half," Black said. "His numbers have been fantastic. Again, the trick is to continue to play at a high level of play ... which he's doing."
