Hanging-tight D-backs host fading Padres

D-backs try to keep up with red-hot Dodgers in NL West race as fading Padres visit for three-game set.

Some have suggested over the past few days that the Diamondbacks are slipping. But though they lost their hold on first place to the Dodgers -- at the hands of the Cubs, no less -- the D-backs enter the weekend just a half-game back in the NL West.


The visiting Padres have slipped even more. At the start of the month, they were in fourth place, just 5 1/2 games back of the D-backs. The Padres have gone 6-10 since then to cap an 8-21 stretch that began June 22.


With the D-backs trying to keep pace with the red-hot Dodgers, who are 14-5 in July, and the visiting Padres trying to get back in contention, here's what to watch for in the three-game series at Chase Field:


PITCHING MATCHUPS: Friday -- RHP Randall Delgado (2-3, 3.43 ERA) vs. LHP Eric Stults (8-8. 3.45). Saturday -- LHP Tyler Skaggs (2-2, 4.11) vs. RHP Andrew Cashner (6-5, 3.84). Sunday -- LHP Patrick Corbin (12-1, 2.31) vs. RHP Tyson Ross (0-4, 3.60).


WHO'S HOT FOR THE D-BACKS: Friday starter Randall Delgado has allowed three runs or fewer in all seven of his starts this season. Over his last five starts (four of them quality starts), Delgado is 2-2 with a 2.93 ERA. ... Third baseman Martin Prado has stayed hot, going 10 for 27 with a double, a triple and six RBI over his past seven games. He has a .419 on-base percentage and a team-best .593 slugging percentage in that span. ... First baseman Paul Goldschmidt is on a tear the past five games, batting .400 (6 for 15) with two doubles, a home run and six RBI.

Though center fielder Adam Eaton has scored seven runs since July 11, he is without an RBI since then and hitting .250 (8 for 32) with one extra-base hit in his 10 games since. ...

Outfielder Chris Denorfia has gone cold since the All-Star break, batting just .083 (1 for 12) with no RBI and no extra-base hits in five games in the second half.


NOTES, QUOTES, ODDS AND ENDS: D-backs catcher Miguel Montero is listed as day-to-day but is dealing with a sore back and could be held out of action for a fourth straight game Friday. In Montero's absence, reserve Wil Nieves has gone 6 for 14 (.429) with two doubles and an RBI. Nieves is batting .369 with 13 RBI in 34 games this season. ... Brad Ziegler is the D-backs' closer until further notice and on Thursday closed out his fifth save in five chances this season. He has not allowed an earned run in nine straight appearances, including 11 straight at home. ... Padres outfield Chris Denorfia has owned Sunday D-backs starter Patrick Corbin in their meetings so far. Denorfia is 7 for 13 (.538) with two doubles, three home runs and three RBI against Corbin.
