Denver,  CO  (SportsNetwork.com) - Carlos Gonzalez's two-run homer highlighted 
Colorado's  six-run  sixth inning, as the  Rockies pounded the Chicago Cubs on 
Wednesday, 13-4, in the middle installment of a three-game set. 

The Cubs led 4-3 through five, but Nolan Arenado doubled in Justin Morneau to 
tie the score and Gonzalez followed with his 11th homer of the season. 

"Hopefully  this is a sign that CarGo is getting on track again," said Rockies 
manager Walt Weiss. "We've seen him have a night like this many times. When he 
gets rolling, it's something to see." 

Chicago starter Jake Arrieta (6-3) allowed four more hits in the inning before 
finally  getting the axe.  He was charged with nine runs on 13 hits over five- 
plus forgettable innings. 

"I  knew  after my bullpen session  that I was going  to have to make a pretty 
substantial adjustment to command the ball," Arrieta said. 

Corey  Dickerson went  4-for-4 with  three RBI  and three  runs scored,  while 
Gonzalez  finished with  three hits  and three  runs in  the victory.  Michael 
McKenry also went yard for the Rockies, who snapped a five-game losing skid. 

Jordan  Lyles  picked up the win  in his return  to the mound following a two- 
month  hiatus  with a broken  left hand. Lyles (6-1)  allowed four runs on six 
hits over six innings of work. 

Chris  Coghlan, like  Dickerson, finished a home  run shy of the cycle for the 
Cubs. Arismendy Alcantara hit his third homer of the season. 

After  Gonzalez made  it 6-4, the Rockies weren't done in the sixth. Dickerson 
doubled  and  McKenry singled  to  put  runners  in  scoring position  for  DJ 
LeMahieu,  who reached  safely on an RBI bunt single down the first-base line. 
Pinch-hitter  Brandon Barnes finally ended Arrieta's outing with an RBI single 
to left. 

The  one positive for Chicago was the return of relief pitcher Kyuji Fujikawa, 
who relieved Arrieta and recorded the final three outs of the sixth in just 10 
pitches.  Fujikawa hadn't pitched since May 26 of last season after undergoing 
Tommy John surgery. 

Dickerson  drove in  two more runs in  the seventh and McKenry added a two-run 
homer to make it 13-4. 

Earlier,   Coghlan  opened  the  game  with  a  triple  to  right-center,  and 
Anthony Rizzo's sacrifice fly gave the Cubs an early 1-0 advantage. 

Alcantara  padded the  cushion in the fourth inning, following Luis Valbuena's 
two-out walk with a home run to right. 

The  Rockies fought  back to tie the score  in the home fourth, with a pair of 
triples  leading to two of the three runs. Morneau hit his third triple of the 
season  and  scored on an Arenado  ground out. With two away, Gonzalez singled 
and  Dickerson  looped a  three-bagger down  the right-field  line to trim the 
deficit  to a run. McKenry knotted the score, grounding the first pitch he saw 
sharply to left.
