The D'backs scored 21 combined runs to sweep an earlier three-game home series against the Cubs in June, but they will be facing a much different team this time around in the Windy City. Let's take a closer look at where your money should land when the two clubs meet at Wrigley Field on Friday and Saturday.

Chicago is no longer the worst team in baseball
 
As of Friday morning, the Cubs have moved a half game ahead of the Houston Astros for the dubious honor of possessing the worst record in baseball. They have won 9 of their last 13 games, including a successful 4-3 road trip against the Atlanta Braves and New York Mets. Arizona ended a recent seven-game homestand with a disappointing 3-4 record, but did manage to win the last three games against the Los Angeles Dodgers. The Diamondbacks are third in the National League West standings coming out of the All-Star break, trailing the first-place Dodgers by four games.
Saturday's Game 2
Dempster will continue auditioning over the weekend
 
Ryan DempsterThere’s a distinct possibility that Ryan Dempster (4-3, 1.99 ERA) could be making his last start in a Cubs uniform, as many teams will have an interest in acquiring the 35-year-old before the July 31 non-waiver trade deadline. He hasn’t allowed a run in his last 27 innings of work, which has led directly to winning his last four starts. In 19 lifetime appearances (15 starts) versus the Diamondbacks, Dempster has compiled a miserable 2-8 record and 6.72 ERA.
 
Joe Saunders (4-5, 3.44 ERA) is expected to return to the mound this weekend after landing on the 15-day disabled list with a strained throwing shoulder. The left-hander hasn’t received much run support over his last four outings, with the offense scoring just five runs in that span. Saunders has dropped both of his career starts against the Cubs, allowing 10 runs (seven earned) and 14 hits over 8.2 combined frames (7.27 ERA).
 
Saturday prediction
 
Weather forecasts suggest partly cloudy skies and game-time temperatures in the mid-80s, with a 5-10 mph breeze out of the south, which should give us a fair number on the total when the MLB betting odds are released for this contest.  The OVER has cashed in six of Dempster’s last seven outings in this series.
 
Pick:  Over
Friday's Game 1
 
Ian KennedyKennedy was tremendous after the break in 2011
 
Diamondbacks starting pitcher Ian Kennedy (6-7, 4.26 ERA) has failed to live up to lofty expectations after a sensational 2011 campaign, but a turnaround may be in the cards in the second half. The right-hander was 12-1 with a 2.11 ERA in 14 starts after the All-Star break last year. In four career starts versus the Cubs, Kennedy has tallied an even 1-1 record and 6.66 ERA, but earned a no decision in a 10-5 home win in this series on June 23. He allowed five runs on a season high-tying 10 hits over 4.1 innings in that effort.
 
Paul Maholm (6-6, 4.57 ERA) has won his last two starts while pitching an inning of scoreless relief in Sunday’s win over the Mets.  The left-hander has done his best work under the sun this season, posting a 4-2 record and 3.43 ERA, with opposing hitters batting .230 against him (.317 at night).  Maholm will be searching for his first career win against the Diamondbacks, entering with an 0-3 mark and 5.34 ERA, and getting saddled with the loss against Kennedy last month.
 
Friday prediction
 
The Diamondbacks are hitting .281 against left-handed pitching over the last 10 games, which has played a major part in winning five of their last six games versus southpaw starters.  Arizona has also produced a 13-5 mark in Kennedy’s last 18 starts when taking on losing opposition.
