González hit 23 homers and led Major League Baseball in that category at the end of May 2009. This despite playing his home games at Petco Park, which Padres statisticians describe as an "extreme pitcher's park." On May 18, González was described as being one of the two most underrated players in the National League according to a poll of Major League executives and managers conducted by MLB.com. On April 1, González was named the NL Co-Player of the Week for the second time in his career. During that week, González hit four home runs, tallied 10 RBIs, and had a 1.000 slugging percentage. González was elected to the 2009 Major League Baseball All-Star Game after voting by fellow players, managers and coaches. He subsequently participated in that year's Home Run Derby where he hit two home runs in the first round. On August 1, González finished 6-for-6 with three RBI as the Padres topped the Milwaukee Brewers 13–6. González's six hits are the most by any Padre in a nine-inning game. Three others have accomplished the feat, but did it in extra-inning contests. González hit five singles and a double.
