How it happened: The Diamondbacks used a six-run fourth to take control. Chicago starter Paul Maholm gave up a single to eight-hole hitter Ryan Roberts and walked opposing pitcher Ian Kennedy to begin the inning, which opened the floodgates. The Cubs scored three runs in the top of the fifth to cut the deficit to 7-5, but four Diamondbacks relievers combined to shut them down the rest of the way. Maholm allowed nine hits and seven runs (six earned) in 3 1/3 innings to fall to 4-6 on the year. He walked three and didn’t strike out a batter. Centerfielder David DeJesus finished 4-for-5 with a double and shortstop Starlin Castro was also 4-for-5. Both players tied career highs for hits in a game. First baseman Steve Clevenger had a two-run double in the fifth.
What it means: After taking two of three games from the White Sox earlier this week, the Cubs were attempting to win back-to-back road series for the first time since Aug. 29-Sept. 11 of last year, when they beat the Giants and the Mets. However, the Diamondbacks have already clinched the three-game set with wins in the first two games heading into Sunday's finale. Chicago has the worst record in baseball at 24-47.
Outside the box: Castro’s considerable offensive prowess was on display again, as he finished 4-for-5 to raise his batting average to .308 on the season. The team’s star shortstop is 13-for-27 in his past six games after his average dipped to .291 on June 16. However, he hasn’t taken a walk since June 2 and Castro has only six walks in 308 plate appearances on the season. While his batting average is 13th in the National League, his on-base percentage of .321 is only two percentage points above the major league average.
Play of the game: Maholm hit his second career home run, a two-run shot to right field, to give the Cubs a 2-1 lead in the top of the fourth. Maholm was 1-for-25 with 16 strikeouts this season prior to that at-bat. His first career home run came on May 9, 2009. He became the first Cubs pitcher to homer since Carlos Zambrano did so on Aug. 6, 2011.
