Valdez (7-8, 4.26 ERA) draws Carmen Mlodzinski (6-5, 3.79 ERA), who has been pressed into rotation duty since Mitch Keller's season-ending arm injury.

Best MLB Betting Promos for Monday, August 17
Every one of the MLB betting promos listed below has been checked by Action Network staff. Below is what each offer pays out, the qualifying wager it takes to trigger, and the code you'll need at registration.
1. Fanatics Sportsbook Promo Code
The Fanatics Sportsbook promo codeACTION26 breaks a $1,000 Bet Match into ten separate days instead of making you dump your promo on one single ticket. This suits bettors who are active throughout a full week rather than once before disappearing. Whatever you lose each day returns as FanCash, so the $100 daily allowance is rebuilt by morning.
The ten-day window lines up neatly with the MLB schedule ahead. Wager on Valdez-Mlodzinski tonight, Braxton Ashcraft on Tuesday, the Paul Skenes finale Wednesday afternoon, and everything Detroit and Pittsburgh play after that.

2. BetMGM Bonus Code
No other entry among these MLB betting promos advertises a bigger figure than the BetMGM bonus code TOPACTION, which stands behind your first wager for as much as $1,500. Aim that opener wherever you like: the Pirates as a live home underdog, a total that PNC Park's dimensions tend to hold down, a Dillon Dingler home run prop after his 26-homer season, or something else entirely.
If the ticket loses, the $1,500 BetMGM promo hands your stake back in bonus bets up to the cap. Because the refund mirrors what you risked, the size of that qualifying bet determines how much of the offer you actually put to work.
| BetMGM Bonus Code | BetMGM Promo | BetMGM Legal States |
|---|---|---|
| BetMGM Bonus Code TOPACTION | $1,500 First Bet Offer | AZ, CO, DC, IA, IL, IN, LA, KS, KY, MA, MD, NC, OH, TN, VA, WY |
| BetMGM Bonus Code TANGET2 | $1,000 No Sweat Tokens | AZ, CO, DC, IA, IL, IN, LA, KS, KY, MD, MO, NC, OH, TN, VA, WY |
| BetMGM Bonus Code ACTIONGET | Bet $10, Get $150 Bonus Bets if You Win | MI, NJ, PA, WV |
3. bet365 Bonus Code
There's no text to enter when signing up with the bet365 bonus code, as registering through the link on this page attaches the offer automatically. As far as MLB betting promos go, the terms couldn't be much cleaner. Risk $10 on any MLB market and $150 in bonus bets land in your account regardless of how your qualifying wager settles.
Use a Valdez strikeout number, the Tigers run line, or a Pacific-time game that starts after the PNC Park finish. The bet365 sign-up bonus credits the same amount either way.
| bet365 Bonus Code | bet365 Welcome Promo | bet365 Legal States |
|---|---|---|
| bet365 Bonus Code (Click Here) | Bet $10, Get $150 in Bonus Bets, Win or Lose | AZ, CO, IA, IN, KS, KY, LA, MD, MO, NC, NJ, OH, PA, VA |
| bet365 Bonus Code (Click Here) | $1,000 First Bet Safety Net | AZ, CO, IA, IL, IN, KS, KY, LA, MD, MO, NC, OH, TN, VA |
| bet365 Bonus Code (Click Here) | Bet $10, Get $150 in Bonus Bets, Win or Lose, 50 Casino Spins | MI, NJ, PA |
4. DraftKings Promo Code
The DraftKings promo code from Action Network also enables itself on the link, and the buy-in is smaller than anything else collected here. Five dollars on any market unlocks $150 in bonus bets, and the credit posts as soon as the wager is accepted, as there no waiting for a final score with this offer.
Bettors wanting bonus bets already sitting in their account by the time ESPN's broadcast opens from Pittsburgh at 7:05 p.m. ET need look no further than the DraftKings sign-up bonus to capitalize on just that.
| DraftKings Promo Code | DraftKings Welcome Offer | DraftKings Legal States |
|---|---|---|
| DraftKings Promo Code (Click Here) | Bet $5, Get $150 Instantly in Bonus Bets | AR, AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, NC, NJ, NY, OH, PA, TN, VA, VT, WV, WY |
5. FanDuel Promo Code
Nothing needs typing for the FanDuel promo code either, and the structure spreads your safety net across five days instead of concentrating it in one wager. Put $5 in play each day and any losing qualifier is reset for up to $200, with $1,000 available in total.
That build rewards the bettor who bets small and often. The FanDuel sign-up bonus can carry you through all three games of this Tigers-Pirates series at PNC Park and still leave two days of coverage for whatever Detroit and Pittsburgh do next.
| FanDuel Promo Code | FanDuel Sign-Up Bonus | FanDuel Legal States |
|---|---|---|
| FanDuel Promo Code (Click Here) | Bet $5 Daily, Get Up To $1000 In Bet Resets | AZ, AR, CO, CT, DC, IL, IA, IN, KS, KY, LA, MA, MD, MI, MO, NC, NJ, NY, OH, PA, TN, VA, VT, WV, WY |
6. theScore Bet Promo Code ACTNEWS
theScore Bet promo code ACTNEWS opens up a $1,000 First Bet Reset, meaning any price on tonight's MLB card is eligible as your qualifier. Should that first wager miss, the stake comes back as bonus bets up to the $1,000 ceiling.
One wrinkle worth knowing is that bettors in Michigan, New Jersey, Pennsylvania and West Virginia are routed to a $100 bet-and-get rather than the reset. Confirm which of these MLB betting promos your state gets before funding the account.
| theScore Bet Promo Code | theScore Bet Welcome Offer | theScore Bet Legal States |
|---|---|---|
| theScore Bet Promo Code ACTNEWS | $1,000 First Bet Reset | AZ, CO, IA, IL, IN, KS, KY, LA, MA, MD, MO, NC, OH, TN, VA |
| theScore Bet Promo Code ACTNEWS | Bet $10, Get $100 in Bonus Bets If You Win | MI, NJ, PA, WV |
7. betPARX Promo Code TANBONUS
The betPARX promo code TANBONUS puts 100% insurance on your opening wager and refunds it as a bonus bet worth if it settles in a loss, up to $50.
That's the smallest cap here, but the sign-up takes roughly two minutes. With the home team playing inside Pennsylvania borders tonight, betPARX is a sensible extra account for Keystone State bettors already working through the rest of these MLB betting promos.
| betPARX Promo Code | betPARX Sign-Up Offer | betPARX Legal States |
|---|---|---|
| betPARX Promo Code TANBONUS | 100% Bet Insurance, Up to $50 Bonus Bet | PA |
8. Hard Rock Bet Promo Code
The Hard Rock Bet promo code is another link-activated offer, and it belongs to the group of bet-and-get MLB betting promos that come with a string attached: your $5 qualifier has to cash before the $150 in bonus bets is released.
Registration is limited to Michigan and New Jersey. Since Hard Rock Bet requires a winner, a heavy favorite from elsewhere on the slate is a smarter qualifier than a Tigers-Pirates game the market has priced as close to a toss-up.
| Hard Rock Bet Promo Code | Hard Rock Bet Welcome Bonus | Hard Rock Bet Legal States |
|---|---|---|
| Hard Rock Bet Promo Code (Click Here) | Bet $5, Get $150 in Bonus Bets if You Win | MI, NJ |
9. BetRivers Bonus Code
No entry is needed for the BetRivers bonus code, though the amount you can recover shifts depending on where you live. The 2nd Chance Bet tops out at $500 in Michigan and Pennsylvania, $250 in New Jersey and $100 in West Virginia.
A losing first bet is returned as a bonus bet, which means the BetRivers sign-up bonus keeps you in business for the late slate even if Mlodzinski or Valdez unravels in the first inning.
| BetRivers Bonus Code | BetRivers Sign-Up Bonus | BetRivers Legal States |

| BetRivers Bonus Code (Click Here) | 2nd Chance Bet: Get Up to a $500 Bonus Bet | MI, PA |

| BetRivers Bonus Code (Click Here) | 2nd Chance Bet: Get Up to a $100 Bonus Bet | WV |
10. Borgata Bonus Code ACTION
Closing out the MLB betting promos rundown is the Borgata bonus code ACTION, available only in New Jersey. Stake $20 and $100 in bonus bets is delivered the instant that wager grades. This offer requires nothing to win and nothing to wait on.
Treat Borgata Sportsbook as the final box to tick for Garden State bettors running through Monday's MLB sign-up bonuses before Valdez takes the mound.

MLB Prediction Markets for Today's Slate
Sportsbook MLB betting promos aren't the only route into Tigers-Pirates. Prediction market apps run sign-up offers of their own, and their state coverage stretches well beyond where regulated sportsbooks operate. This is useful tonight when the national ESPN feed reaches nationwide, while online sportsbooks are limited to legal sports betting states.
1. Kalshi Promo Code ACTION
The Kalshi promo code ACTION gives new traders a bonus of up to $500 after $25 of volume settles. Kalshi operates in more than 40 states, putting the PNC Park opener in play for a large group of people with no legal sportsbook option at home.

2. Polymarket Promo Code ACTION
The Polymarket promo codeACTION asks the least of the two prediction market offers and settles quickest. Deposit $10 and a $20 trading bonus follows. Availability spans 40-plus states, making it a logical companion to a Kalshi account rather than a substitute.
