Today's best MLB strikeout prop bets and pitcher K props for Monday, June 15. Thunder Dan's expert MLB player prop picks, betting odds, and advanced stat analysis to help you win.
Mondays are usually slower in MLB, but today, we have only two-thirds of the teams in action. There aren't too many aces on the bump either, with Chase Burns being the only real notable one going tonight. Sorry, Zack Wheeler, you're not the ace in Philly anymore, and I can't really refer to Shota Imanaga as an ace either, with how he's pitched over the last month.
But the lack of high-end arms does present us with a chance to attack a lot of the lower prop numbers today, too, and there are a lot of 4.5 K props that have me interested! If you want the remaining strikeout bets, you'll need to grab a premium pass to see all eight of my favorite K prop wagers.

High-Confidence Strikeout Picks
All odds were current as of 8:00 AM ET
Chase Burns (vs. NYM) OVER 7.5 strikeouts (+133 Novig)
As I mentioned in the opener, Burns is pretty easily the best strikeout pitcher on the mound tonight. He checks all the boxes of an elite K arm, with a 29.6% K% and 15.1% SwStr%. He has the walks under control (7.7%) and has also been improving his batted-ball results, with a sparkling 2.95 xERA.

He posted eight strikeouts against this Mets team when he first faced them three weeks ago. The Mets are striking out even more often since then, with the third-worst K% vs. RHP over the last two weeks at 25%. The final green light for me is that Burns has been even better against lefties this year (32.2% K%), and the Mets' lineup is projected to have six lefties in it tonight.
Most of these left-handed sticks are younger hitters with big K-rates to RHP this season. Check out these splits.
- Carson Benge (22.9%)
- Jared Young (22.1%)
- Brett Baty (29.1%)
- A.J. Ewing (33.3%)
- MJ Melendez (37.9%)
Burns got all of them at least once in that first start, too. It's a big number for him to get eight tonight, but he's done it six times already this season, including in three of his last four outings. The odds are fantastic, the matchup is great, and I'm betting on Burns's talent to get it done.
Walbert Urena (at ARI) OVER 4.5 strikeouts (+141 Novig)
Don't look now, but Urena is really starting to figure out how to utilize his arsenal of pitches to get more strikeouts. He's averaging 6.25 strikeouts per start over his last four outings and has posted seven strikeouts in both of his most recent starts.

Urena can hit triple digits with his heater, but it's his low-90s changeup that has been a tremendous out pitch for him this year. He's still walking far too many hitters (13.6%), which shortens his outings a bit, but the strikeouts have still been there, and he's slowly raising his SwStr% to a solid 11.4%.
Arizona is a pretty neutral matchup at 22% K% vs. RHP over the last two weeks, but this offense has really slowed down lately, with just a 77 wRC+ during that same stretch. They were limited to just one earned run total by mediocre arms such as Ryan Gusto and Rhett Lowder the last two times they faced a right-handed starter.
Urena has the stuff to get 5+ strikeouts today for the fifth straight time, and these odds over on Novig are tremendous, so take advantage!
