The 2013 MLB betting season is now over 50 games old for the mass majority of teams in the bigs, and we're going to be looking at the ones that have really struggled on the road over the course of the start of the season today at Bang the Book.

Miami Marlins (6-21, -$1,091) - Doesn't it sort of feel like you're watching Bull Durham when you're watching the Marlins? It feels like the line should go something like this… "What's our record on the road, Larry?" "Six and 21." "Six… and 21. How'd we ever win six?" "It's a miracle." It's hard to not sit and laugh at the Marlins. They have lost seven road games in a row, and they have two road wins since May 5th. They have allowed at least seven runs three times in their last six on the road, and they have scored three runs or fewer and five of their last seven on the road. Interleague play didn't help either. The Fish were beaten in both of their games by Tampa Bay, even with the DH in the lineup.

Seattle Mariners (9-18, -$807) - There aren't many teams in baseball that don't have at least 10 wins on the road this year, but the Mariners are one of them. Granted, it's always tough to go on the road if you're the M's because you're so darn far away from the rest of the teams that you have to play against night in and night out. The team did win two out of three at Yankee Stadium in the middle of the month, but since then in trips to Cleveland and LA, Seattle is 0-6, and it has been shut out in two of those games and held to three runs or fewer in all but one of those outings. Even RHP Felix Hernandez, who is supposed to be one of the best pitchers in the game, has lost his last two road starts.

San Francisco Giants (9-15, -$702) - RHP Matt Cain wants to know when he is going to get some help. He has led the team to 2-0 record on the road since May 1st. The rest of the team is 0-7 since that point. Simply put, the Giants just aren't hitting the ball right now. They scored two runs in their final two games against the Rockies at Coors Field, and in their two games played over in the American League this week against the A's, they managed just 10 total hits and four runs in two losses. That's just not going to get the job done for this team, and there is no doubt whatsoever that San Francisco is going to need to play better than this on the road if it is going to ultimately find a way to win the NL West again this year.

Los Angeles Angels (11-16, -$678) - The Angels aren't going to be on this list for much longer if they find a way to keep this up. The team had won eight games on the road, including taking all four games of a crucial series against the Royals in Kansas City before losing to the Dodgers both on Monday and Tuesday. It's not the end of the world for the team though, as LA had to run up against LHP Hyun-Jin Ryu and RHP Zack Greinke in those two games, and most teams would be thrilled to walk away with their dignity intact from those games more than anything else. What really turned things around were the two losses that the team suffered in Houston on May 7th and 8th. That's when Manager Mike Scioscia probably should have been fired. However, since that point, the Halos have been playing good ball, and they are probably a good month of June away from being back in the thick of the fight.

Los Angeles Dodgers (8-13, -$611) - The Dodgers haven't been getting enough run support on the road at all. For example, LHP Clayton Kershaw has pitched in four games on the road this year. Opponents have been held down to 1, 2, 2, and 3 runs in those four games. There is no way in the world that LA should only be 2-2 in those games, but the truth of the matter is that it is lucky not to be 1-3 in those outings. The offense has been terrible, scoring three runs or fewer in 13 of 21 road games this year.
