Chicago,  IL  (SportsNetwork.com) - Jake  Arrieta got  back on track by firing 
seven  strong innings  and leading the Chicago Cubs to a 3-1 victory over the 
Colorado Rockies that closed out a four-game series. 

Arrieta (6-2) took a perfect game into the fifth inning and yielded just a run 
on three hits while striking out seven to halt a four-start winless stretch. 

The  right-hander was bolstered by a big sixth inning in which the Cubs scored 
three runs off Pedro Hernandez despite recording only two hits. 

Chris  Coghlan went  2-for-3 with a run  scored in the win, Chicago's third of 
the set. 

The  NL Central cellar-dwelling Cubs made one notable move at Thursday's trade 
deadline  during the  game,  shipping utilityman  Emilio  Bonifacio and  lefty 
reliever James Russell to Atlanta for minor league catcher Victor Caratini. 

Hernandez  (0-1), promoted  from Triple-A Colorado Springs for his first major 
league  start of  the season, permitted all  three runs on six hits over 5 2/3 
innings. 

Arrieta opened the contest by setting down 14 consecutive hitters -- including 
six  by strikeout -- before Wilin Rosario broke up the perfect-game bid with a 
two-out single in the fifth inning. 

"It's kind of one of those things where the more you go out there and continue 
to  do it, it  just seems like it's supposed to happen that way," said Arrieta 
of  his early success.  "It's a good feeling when you get into that groove and 
you're able to execute pitch after pitch." 

Hernandez  nearly matched his counterpart over the first five frames, however, 
scattering  four singles and  inducing a pair of double plays to keep the game 
scoreless entering the sixth. 

He  was reached for back-to-back singles by Arismendy Alcantara and Coghlan to 
start  Chicago's half  of the  sixth, though,  then walked  Anthony Rizzo  and 
Starlin  Castro  in succession  to force in  a run. A  sacrifice fly by Justin 
Ruggiano  plated Coghlan for a 2-0 lead, with Rizzo scoring on Luis Valbuena's 
grounder to short to extend the margin. 

Colorado  finally  got to  Arrieta in  the seventh,  as Nolan Arenado followed 
Corey  Dickerson's leadoff  single with a run-scoring double, then put forth a 
threat against Cubs closer Hector Rondon in the ninth. 

Arenado  and  Morneau began  the inning  with base  hits to  put the tying run 
aboard, with Arenado advancing to third on Carlos Gonzalez's fielder's choice. 
Rondon  got a  key strikeout of Rosario, however, and fanned Charlie Culberson 
looking to notch his 14th save of the year. 

"We  just  couldn't get  the big  hit to  put together  a big inning," Rockies 
manager Walt Weiss said afterward.
