Baseball bettors are a month into the 2015 MLB campaign and if you’re a regular of sportsbook online betting, you’ve noticed these teams lighting up the scoreboard to start the season.

Here are the most outstanding – but still early – MLB Over bets:

Oakland Athletics (11-16 SU, 20-6-1 O/U)

Not all great Over bets are great scoring teams. Some are horrible defensive units. And then you have the perfect storm of great offense and poor defense, such is the Oakland A’s. They’ve been bashing the cover off the ball through the first month of play, averaging 5.11 runs on a .268 BA, but also giving up plenty of runs on the other side of the plate. Oakland’s bullpen is to blame, boasting a chunky 4.93 ERA and five blown saves already. The A’s are a profitable 12-1 O/U in the Bay Area but don’t return home until May 11, facing a pair of Sox – Red and White – for six games.

San Diego Padres (14-13 SU, 16-10-1 O/U)

Often times early-season results can catch oddsmakers off guard, and that’s what we’ve seen from San Diego. The Padres have been perennial whiffers at the plate, ranking near the bottom of most batting categories over the past few season. But, this year’s club is plating 4.85 runs per game while the betting market still looks at them as a low-scoring team. These miscalculations don’t last long and we’ve already seen the Under show up a couple times in San Diego’s recent outings. The Padres were the best Under bet in baseball last season, with a 61-95-6 O/U mark.

Boston Red Sox (12-14 SU, 16-10-0 O/U)

If you’re going to survive in the American League East, you better have plenty of pop. Boston has that offensive prowess, averaging 4.73 runs with 29 total home runs, but can’t seem to figure out how to stop opponents from posting similar outputs. The Red Sox have a horrendous 5.04 ERA and just 11 quality starts out of its rotation to start the season. Things have gotten out of hand away from Fenway, with Boston boasting a 9-3 O/U road record for those doing sportsbook online betting. Boston hits the road for a 10-game road swing this Friday, starting in Toronto.
