WATCH Diamondbacks vs. Pirates Live Stream Online: Free MLB 2015 Game 1 Coverage

Baseball's back for the official 2015 MLB season, and things are finally heating up!

The Arizona Diamondbacks take the field against the Pittsburgh Pirates in Week 20 of the regular season on Monday, August 17 at 7:05 p.m. EST at PNC Park in PA. Read on to see where fans can watch and listen to a live stream of the Game 1 evening ballgame online - also catch up-to-date feeds and coverage on highlight plays and scores.

While the Pirates maintain an extremely high spot in ESPN.com's official break-down of all 30 professional teams (power rankings), the Diamondbacks don't lag far behind:

Pirates (3): "After sweeping the Mets, the Pirates concluded a tough 11-game stretch against the Mets, Cardinals, Dodgers and Cubs with an 8-3 record. Only seven of their next 27 games are against teams with winning records." David Schoenfield, SweetSpot 

Pittsburgh now holds an impressive 69-46 winning record and remains 2nd in the National League Central Division.

Diamondbacks (16): "Although Paul Goldschmidt has "cooled off" at the plate in the last month, outfielder David Peralta has picked up the slack. Since the All-Star break, he's hitting .443 (35-for-79), including four triples and four homers. A former pitcher the D-backs converted out of independent ball in 2013, Peralta is here to stay as he's put himself on the map as one of the team's best assets." Jeff Wiser, Inside the 'Zona

With that, Arizona maintains 57 wins and 59 losses and is now 3rd in the National League Western Division.

The Monday night ballgame will be broadcasted live on local sports channels RTPT and FSAZ.
