Rapid Reaction: Reds 5, Cubs 0

CHICAGO -- Here's a quick look at the Chicago Cubs' 5-0 loss to the Cincinnati Reds on Wednesday:

How it happened: The Cubs were shut out for the fourth time in the past five home games. The Cubs started a makeshift lineup which included a number of bench players in the series finale. Manager Dale Sveum gave slumping shortstop Starlin Castro, Junior Lake and Darwin Barney a day off. Starting pitcher Chris Rusin fell behind in the first inning, surrendering a home run to Reds third baseman Todd Frazier. Reds starter Bronson Arroyo retired the first nine Cubs he faced before David DeJesus led off the fourth with a single to center field, one of just two Cubs hits on the day. Rusin left after six innings, giving up just two runs in a second straight quality start.

What it means: Cincinnati completes the sweep of the series and Arroyo has defeated the Cubs in four straight appearances dating back to last season. The Cubs have lost 10 of their last 11 games at home after losing the finale of the series finale to Cincinnati. Chicago has lost 13 of the first 16 games between the two division rivals this season. Former starter Carlos Villanueva, who was demoted from the rotation before the game, gave up three runs in relief of Rusin.

Outside the box: The Cubs promoted pitcher Jake Arrieta from Triple-A Iowa and he will start Friday's game against the St. Louis Cardinals. ... Reliever Matt Guerrier said he will need surgery to repair a tear between his right forearm and elbow. Guerrier said the rehab will take between six to eight months. Guerrier was placed on the 60-day DL on Thursday.

Up next: After an off day on Thursday, Arrietta makes his second start of the season for the Cubs, opening a three-game series against the Cardinals at 3:05 p.m. CT Friday.
