Today's Top Major League Baseball Exposures - June 28: Diamondbacks

The Arizona Diamondbacks are by far the most wagered on side in Major League Baseball, which can only mean one thing - Bet against them.

This may be the general rule here at Gambling911.com but that doesn't always work out.  In fact, this one we will be sitting out.

Just shy of 90% of the action is on Arizona in Miami as a -167 favorite.  The line has moved little.

Arizona has won six of the last seven meetings.

PITCHING MATCHUP: Diamondbacks RH Zack Greinke (7-5, 3.66 ERA) vs. Marlins RH Trevor Richards (2-4, 4.91)

Greinke has won four of his last five starts, capped by a win at Pittsburgh on Saturday in which he allowed two hits over six scoreless innings with seven strikeouts.

Richards registered one of the best performances of his young career last Saturday when he held Colorado to one run, three hits and two walks with eight strikeouts over six innings.

The Illinois native has permitted one run or fewer in four of his last seven outings as he prepares to meet the Diamondbacks for the first time.
