Thursday's series opener between the Giants (24-17) and Rockies (21-20) was mostly an offensive showcase, with the two teams combining for 14 runs in the first six innings.
If the last meeting between Friday's starting pitchers is any indication, the second matchup of the four-game series at Coors Field is unlikely to resemble the first.
San Francisco's Madison Bumgarner and Colorado's Jorge De La Rosa will take the mound on Friday a little more than a month after squaring off at AT&T Park on April 8. Bumgarner's Giants got the better of De La Rosa's Rockies, 4-2, but as San Francisco's 23-year-old left-hander said, it wasn't easy.
"Pretty much every inning felt like a battle," Bumgarner said after the win.
In 5 2/3 innings, Bumgarner allowed two runs on five hits on the way to besting De La Rosa, who went six innings and didn't surrender a run after Hunter Pence's three-run homer in the first.
Since that matchup, Bumgarner is 2-1 with a 2.48 ERA while De La Rosa is 4-2 with a 2.06 ERA and carries a 14-inning scoreless streak into Friday's showdown.
On Sunday, De La Rosa no-hit the Cardinals into the seventh inning on the way to an 8-2 win.
"He's dominated some good lineups in this league," Rockies manager Walt Weiss said of De La Rosa. "When he's commanding his stuff, he's one of the tougher left-handers in the National League."
Colorado could use another strong outing from De La Rosa, as they try to snap the longest active losing streak (10) against a division opponent in the Majors. The defending World Series champions are 31-9 against the Rockies since the start of the 2011 season, including a three-game sweep earlier this season and a 14-4 mark in 2012.
Rockies: LeMahieu gets called up, notches base hit
DJ LeMahieu thought he should have been on the Rockies' Opening Day roster after hitting .297 with two home runs and 22 RBIs in 81 games last year with Colorado. On Thursday, the 24-year-old infielder was recalled from Triple-A Colorado Springs, and LeMahieu showed his worth as soon as he could, delivering a pinch-hit single and swiping second base in the sixth inning.
It was a long time coming for the young infielder.
"I was disappointed, yeah," LeMahieu said of not starting the season with the Rockies. "I thought I played really well at the end of last year. At the same time, I think it kind of helped me to prove that I do belong here. I think that kind of fueled me to play better."
Giants: Comebacks continue
Starting pitcher Matt Cain spotted the Rockies six runs on Thursday before the Giants' bats came alive and carried the team to an 8-6 win.
For San Francisco, battling back from behind was nothing new. Half of the Giants' 24 wins this season have been by way of a comeback, while eight wins came after San Francisco was trailing or tied going into the eighth inning.
• San Francisco is the only NL West team Colorado has not beaten this season (0-4).
• Marco Scutaro extended his hitting streak to 15 games by going 2-for-5 on Thursday. He was tied with the Dodgers' Matt Kemp and the Twins' Joe Mauer for the longest active hitting streak in the Majors, but neither player had a game on Thursday.
• The Giants are 12-2 in their last 14 games against the Rockies at Coors Field entering Friday night.
