Today at 4:35 p.m. ET, the Colorado Rockies (4-2) and San Francisco Giants (3-4) take the field for the first meeting in a three-game set live from AT&T Park in San Francisco.

Colorado embarks on a six-game road trip while San Francisco returns home for the first time since winning the World Series and will remain at AT&T Park for the next 10 contests.

The Rockies opened up the season with four straight wins, but fell to the Chicago Cubs in back-to-back games to lose their weekend three-match set. The Giants have dropped three straight games after defeating the San Diego Padres to open their four-game series on Friday.

Eddie Butler (0-0, 3.18 ERA) toes the rubber for Colorado in his fifth-career start while San Francisco counters with rookie Chris Heston, who is also 0-0 along with no ERA after his first-career start.

The Giants will celebrate winning their third World Series in five years after knocking off the Kansas City Royals last October in the Fall Classic.

After that, they'll send Heston to the mound, marking just the second time that a rookie started a home opener since the team moved to San Francisco in 1956. The Giants are 35-21 overall and 11-3 at AT&T Park in home openers since 1958.

San Francisco enters play looking to avoid its fourth straight loss after a 6-4 setback against San Diego on Sunday.

Catcher Buster Posey hit his second homer of the season in the loss while center fielder Nori Aoki has a 15-game hitting streak dating back to last season.

Colorado is coming in on the heels of a tough 6-5 loss to the Cubs on Sunday after Chicago rallied for three runs in the top of the ninth inning.

Center fielder Charlie Blackmon had three hits, an RBI and a run in the game while second baseman DJ LeMahieu picked up his fifth RBI of the campaign and hit safely for the sixth straight game. This begins a string of 25 consecutive NL West matchups for the Rockies.

The World Series champions return home when the Giants host the Rockies live this afternoon from AT&T Park in San Francisco.
