It's Thursday, which means we've got various game happening throughout the afternoon in Major League Baseball.
I've got three bets that I'll be sweating out today, so let's get to it with my MLB plays and predictions for Thursday, May 7.
Minnesota Twins vs Washington Nationals
It's Simeon Woods Richardson day, which is always significant to point out for us bettors. He's currently 0-5 through seven starts with a 6.49 ERA and a 6.46 FIP. His strikeout-to-walk ratio is below 2%, he has a 1.76 WHIP and a 5.71 SIERA (Skill Interactive ERA).
The list of atrocities goes on and on, but suffice to say, Woods Richardson has been a poor pitcher.
There is a chance he could look halfway competent against this Nationals lineup, which ranks dead last in wRC+ (72) over the past couple of weeks against right-handed pitching. Then again, the other side of that coin is Washington finally finding its spark against one of the worst pitchers in Major League Baseball.
As for the home team, they'll be sending Jake Irvin to the bump, and despite his 1-4 record and 4.93 ERA, his underlying numbers are a bit more promising.
Irvin's FIP sits at 4.03, he's keeping home run damage relatively low at 9%, his BABIP is .283 and his SIERA is 3.90.
There's a lot more to be optimistic about with the Nationals' starting pitcher than the Twins' this evening.
Washington is coming off a 15-2 bludgeoning of Minnesota on Wednesday night, and perhaps it'll be able to carry that offensive momentum into tonight's contest against a terrible pitcher – at least that's what I'm banking on.
Play: Washington Nationals Moneyline (-120)
Cincinnati Reds vs Chicago Cubs

The Chicago Cubs are the most electric team in baseball at the moment, and if you've been betting them lately, then you've been a happy person.
The @Cubs over their last 20 games:
17 total wins
10 comeback wins
9 wins after allowing the first run
6 one-run wins
4 walkoff wins
4 wins after trailing in 8th or later
3 extra-inning winsNo other MLB team in the modern era has done all of that over any 20-game span. pic.twitter.com/65oRrdidb5

Pittsburgh Pirates vs Arizona Diamondbacks
We've got a rubber-match down in the desert, as the Pittsburgh Pirates and Arizona Diamondbacks are both itching to collect this series win on Thursday.
Right-hander Zac Gallen will get the nod for the home team. It's been an underwhelming season so far for the veteran righty, posting a 1-2 record with a 4.45 ERA .339 BABIP and 7% strikeout-to-walk rate through seven starts.
Still, there are some positive areas to acknowledge. His FIP shows 3.63, is HR/FB ratio is 5.4% and he's producing grounders at a rate of 49%.
The Pirates have been a solid squad as of late, ranking in the top-10 in both wRC+ and OPS against right-handed pitching the past couple of weeks. Be that as it may, I still view this as a quality position for Gallen to settle in and deliver a strong performance.
On the flip side, fellow right-hander and 30-year-old Mitch Keller will start for the visiting ball club. He's got a 3-1 record through seven outings, along with a 2.85 ERA, and 2.89 FIP. His ground ball rate is a tad lower at 39.8%, and his expected ERA (3.77), xFIP (3.97) and SIERA (4.28) hint at some regression.
Can it come agains an Arizona lineup that's hitting a 95 wRC+, .697 OPS and .172 ISO against righties the past couple of weeks? I sure hope so, because I'm backing the Diamondbacks on the moneyline this evening.
Play: Arizona Diamondbacks Moneyline (-110)
