In true American League spirit this season, a pair of sub-.500 teams square off tonight. The Texas Rangers host the Kansas City Royals for a battle between underperforming squads. Someone has to win, but which one will it be?

Here’s a betting prediction and pick for tonight’s Royals vs. Rangers matchup courtesy of MLB odds and lines on DraftKings Sportsbook.

Royals vs. Rangers prediction, preview

Kansas City Royals

The Royals just can’t seem to find their form, dropping to 22-34 in the AL Central. That record places them fourth in the division, and a 3-7 record across their last 10 games as well as a 10-15 mark in May certainly don’t help the outlook. They’ve now dropped to 26th in OPS at .683 with 3.77 runs per game, the second fewest of any team. A full slash line of .234/.308/.375 leaves much to be desired, and a .141 ISO with 51 homers are both on the lower end of average. While their plate process is fine with an 0.42 BB/K ratio, the thing holding the offense back remains a .227 AVG with RISP. The pitching staff is also subpar overall, amassing a 4.44 ERA and 1.39 WHIP with a 10.7% K-BB%. The bullpen is a major point of weakness in particular, generating a 5.02 ERA, 1.55 WHIP and 8.3% K-BB% — all of which are bottom-five marks.

RHP Stephen Kolek draws the start for the Royals tonight with a 3-0 record in four appearances. He brings a low 2.77 ERA and 0.85 WHIP into the outing, though he’s struck out just 14 hitters in 26.0 IP. His BB% of 5.1% is elite and he’s limiting barrels well, too.

Texas Rangers

The Rangers are still competitive in a weak AL West, but a 25-31 record places them fourth despite being just 2.5 games shy of first. They’re only 3-7 over their own last 10 games as well, dropping three-of-four to the Astros in their last series. Much like Kansas City, this offense continues to underperform with only 3.84 runs per game and a .684 OPS that ranks 24th in baseball. The full slash line reads .230/.312/.372 with a .142 ISO and 55 homers. Texas’ BB/K ratio also comes in at 0.41, though a 23.0% K% is on the higher end. The arms are the primary reason this team is even competitive, bringing the ninth-best ERA at 3.76 along with a 1.21 WHIP and 14.0% K-BB%. Narrow it down to the relievers alone and the ERA comes down to 3.10, tied for third, along with a 1.22 WHIP and 10.1% K-BB%.

LHP MacKenzie Gore gets the start for the Rangers this evening with a 3-4 record through 11 appearances. He’s amassed a 4.42 ERA, 1.24 WHIP and 62 punchouts in 55.0 IP. His 26.6% K% is quite respectable, but he’s struggled with his command some at an 11.2% BB%.

Royals vs. Rangers pick, best bet

DraftKings Sportsbook lists the Rangers as -131 Moneyline favorites at home tonight. The Royals come in at +109 odds to win outright. The run total sits at 7.5 combined runs between these sides.

Best Bet: Stephen Kolek under 3.5 strikeouts (-107)

Even against a team that has a slightly elevated K% at the dish, I’m not sure I like the over on Stephen Kolek’s strikeout prop. The guy just pitched a complete game shutout in his last outing but punched out only two batters in that one. Again, that’s two Ks across a while nine innings of work! He’s stayed under 3.5 strikeouts in three of his four appearances so far, throwing at least six innings in each of those three. The one game he went over the line was a six-strikeout outing in 4.2 IP. With a sixth-percentile K% of 14.3%, a second-percentile whiff rate and 21st-percentile chase rate, he shouldn’t get a ton of punchouts today either. This is just Kolek’s game, as evidenced by a 16.7% K% last year and an 18.5% mark in 2024 out of the bullpen.
