Bumgarner, the Giants' 25-year-old left-hander, was recognized Wednesday for his dominant August performance by being named National League Pitcher of the Month. He also won the award in May. Kershaw, Los Angeles' lefty ace, earned the league's top pitching honor in June and July.
Kershaw also received votes in the balloting for August.
"It's hard to see how anybody could beat him out, the way he's been throwing," Bumgarner said.
The same could be said about Bumgarner, who struck out a league-high 56 batters while walking three in six August starts. He finished with a 4-1 record and a 1.57 ERA while logging 46 innings, another NL high. Additionally, opponents batted .164 off Bumgarner, the second-lowest mark among qualifying NL pitchers.
Kershaw virtually matched Bumgarner in August, posting a 3-1 mark with a 1.80 ERA, 44 strikeouts and eight walks in 40 innings.
Bumgarner never has preoccupied himself with individual deeds.
"It's not why I'm here," he said. "But it's a good accomplishment. I couldn't have done it without everybody. We played really good offense and unbelievable defense [in August]."
Bumgarner began his big month with a two-hit shutout at New York on Aug. 3. He added a one-hit shutout over Colorado on Aug. 26 in which he maintained a perfect game for seven innings and matched a personal best with 13 strikeouts.
