WATCH Cubs vs. Pirates Online Live Stream, Top Teams Doubleheader: Free MLB 2015 Game Coverage

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

The Chicago Cubs take the field against the Pittsburgh Pirates in Week 24 of the regular season on Tuesday, September 15 at 1:35 AND 7:05 p.m. EST at PNC Park in Pennsylvania. Read on to see where fans can watch and listen to a live stream of the Game 1 and 2 doubleheader ballgames online - also catch up-to-date feeds and coverage on highlight plays and scores.

Both the Cubs and Pirates maintain rather high spots in ESPN.com's official break-down of all 30 professional teams (power rankings):

Pirates (4): "They start the week just 2½ games behind the Cardinals, the closest they've been to first place since April 27 - a position they haven't been in all season after starting 0-3. But they face the Cubs at home and the Dodgers on the road this week." David Schoenfield, SweetSpot 

Pittsburgh now holds an impressive 86-56 winning record and is now 2nd in the National League Central Division.

Cubs (6): "Jake Arrieta picked up his 19th win of the season on Friday, becoming the first Cub to reach 19 wins since Jon Lieber went 20-6 in 2001 and the first Cub under 30 to do it since Greg Maddux won 20 in 1992." Joe Aiello, View from the Bleachers 

With that, Chicago snags 82 wins and 60 losses and still remains 3rd in the National League Central Division.

Both ballgames will be broadcasted live on local sports channels CSPh and RTPT (and later WGN).
