Last Meeting ( Sep 15, 2012 ) San Francisco 3, Arizona 2

The San Francisco Giants look to complete a three-game sweep of the Arizona Diamondbacks on Sunday and extend their winning streak to five. The Giants are 19-10 in the month since All-Star outfielder Melky Cabrera was suspended for using performance-enhancing drugs, and they’re 7 1/2 games ahead of the Los Angeles Dodgers in the National League West. Things are quite different for the Diamondbacks, who have scored four runs or less in 12 consecutive home games, tying the 2004 team for the longest streak in franchise history. Arizona, which is 2-8 in its last nine at Chase Field, stands 4 1/2 games behind St. Louis and Los Angeles in the race for the second wild card spot.

One reason the Giants haven’t missed Cabrera as much as expected has been the play of center fielder Angel Pagan, who ripped a triple on Saturday. His 13th triple broke a single season San Francisco record that was previously shared by Willie Mays (1960) and Steve Finley (2006). Buster Posey is expected to start at catcher in Sunday’s series finale after playing at first on Saturday. Posey, who has started 24 games at first and 101 at catcher this season, leads the majors in both stolen-base attempts against (80) and runners thrown out (28). Arizona heads into Sunday’s game in need of more power from first baseman Paul Goldschmidt, who hasn't homered in 27 contests. Outfielder Jason Kubel is batting .125 (8-for-64) in his past 19 games.
