Best MLB pitchers to bet on | Worst

Yesterday, we examined the 10 most profitable pitchers to bet on in baseball's first half. Because the glass certainly isn't always half full when it comes to Vegas, today it's time to look at the opposite end of the spectrum.

One of the most eye-popping aspects of the 10 least profitable pitchers in the first half of the MLB regular season is the glamor behind some of these names. These 10 starters have a combined 14 seasons' worth of 15-plus wins under their belt, which is why if you're betting baseball, you can't blindly bet for a team even when its ace is on the mound.

Here are the 10 least profitable pitchers of the first half of the MLB season (based on making $100 per wager) and whether you should bet or fade them in the second half:

1. Joe Blanton, Los Angeles Angels

Money profited: -$1,513
Team W-L: 4-15
Average betting line as favorite: minus-140 (13 starts)
Average betting line as underdog: plus-124.5 (six starts)

To become the least profitable pitcher in baseball, you need to be a favorite in the majority of your starts (13), your ERA (5.53) and WHIP (1.55) need to be close to embarrassing, and the team you pitch for needs to keep sending you out there (19 starts). Blanton unfortunately has check marks for all three.

He's ranked 50th overall in run support, receiving 4.05 runs per game, which is 0.57 runs less than the Angels' per game average (4.62). One of Blanton's downfalls this season has been his atrocious (and unlucky) BABIP of .339, which is the second-worst in baseball. That said, it's hard to expect things to improve significantly in the second half.

Projected opponents after All-Star break: Twins (H), Athletics (R), Blue Jays (H), Rangers (H) (*H= Home, R=Road)

Fade or bet: Don't fade, don't bet ... stay far, far away
