Bryan Woo has allowed just 2 earned runs in 13 innings this season. His 0.54 WHIP ranks 3rd in all of baseball. Only 5 hits allowed. Fifteen strikeouts. A 1.38 ERA that screams ace-level dominance. And somehow, you're getting his earned runs under at +100. Even money. This is the first time all season that the books have offered Woo's ER under without making you pay juice. When a pitcher with the third-best WHIP in baseball is available at plus money on his earned runs prop, you don't overthink it. You take it.
Let's start with the number that matters most for earned runs props: WHIP. Bryan Woo's 0.54 WHIP ranks 3rd in all of Major League Baseball. That's not a typo. Through 13 innings of work in 2026, Woo has allowed just 5 hits and 2 walks combined. That's 7 total baserunners. In 13 innings. The man is simply not letting anyone get on base, and when nobody's on base, nobody's scoring.
Think about what a 0.54 WHIP actually means in practice. For every inning Woo pitches, you'd expect roughly half a baserunner. That means in a typical 6-inning start, he's putting approximately 3 people on base total. Three baserunners in an entire start. And those 3 baserunners need to string together hits, advances, and scoring opportunities against a pitcher who is dealing at an elite level. The math just doesn't support earned runs piling up against a guy with this kind of WHIP.
| Metric | Bryan Woo 2026 | 2025 Season | Assessment |
|---|---|---|---|
| ERA | 1.38 | 2.94 | Elite |
| WHIP | 0.54 | 0.93 | 3rd in MLB |
| Strikeouts | 15 in 13 IP | 198 in 186.2 IP | Dominant |
| Hits Allowed | 5 | -- | Stingy |
| Earned Runs | 2 total | -- | Ace-Level |
This isn't a fluke. Woo was an All-Star in 2025, finishing the season with a 2.94 ERA, a 0.93 WHIP, and 198 strikeouts in 186.2 innings. He established himself as one of the premier pitchers in the American League last season, and 2026 has been a continuation of that trajectory. If anything, the WHIP has gotten even more ridiculous. His 0.93 WHIP in 2025 was already well above average. The 0.54 he's running right now is borderline absurd. You're betting on a pitcher who proved it over a full season last year and has somehow raised his game even higher to start this one.
His last start tells you everything you need to know. Seven scoreless innings. Six strikeouts. Only 3 baserunners the entire game. Woo went out there and was so dominant that the opposing lineup barely had a pulse. When a pitcher is rolling like this, with this kind of command and this kind of stuff, the earned runs under becomes one of the most reliable props on the board. You're not hoping he's good. You already know he's good. You've got 13 innings of proof in 2026 and an entire All-Star season in 2025 backing it up.
Here's what makes this play special. Yesterday, we took Tarik Skubal's earned runs under against the Twins and had to lay -160 for it. That's the price you pay for the best pitcher in baseball. Today, you're getting Bryan Woo, a pitcher with a lower WHIP than Skubal right now, at +100. Even money. You risk 1 unit to win 1 unit. No juice. No tax. Just a coin flip price on a pitcher who is statistically one of the three most difficult pitchers to reach base against in all of baseball.
Skubal ER Under yesterday: -160 (you risk $160 to win $100). Woo ER Under today: +100 (you risk $100 to win $100). Woo's 0.54 WHIP is actually lower than Skubal's current WHIP. Both have allowed 2 or fewer earned runs through their first 13 innings of the season. Both are striking out more than a batter per inning. The difference? The books are charging you 60 cents less on Woo. This is the kind of pricing inefficiency that sharp bettors live for. The market hasn't fully adjusted to just how dominant Woo has been, and you're getting him at a price that doesn't reflect his performance.
This is the first time all season you're getting Woo's earned runs under at even money. His previous starts had this line juiced to the under side, as it should be for a pitcher this good. Something about the road start at Globe Life Field, or the fact that Texas is on a 2-game win streak, has pushed this line to even. Whatever the reason, the market is giving you a window. These windows don't stay open long. When a pitcher is posting a 0.54 WHIP and you can get his ER under at plus money, the value is screaming at you.
At +100 odds, you only need this to hit 50% of the time to break even. Fifty percent. For a pitcher who has allowed 2 earned runs in 13 innings this season. For a pitcher who was an All-Star last year. For a pitcher with the 3rd-best WHIP in baseball. The breakeven threshold is absurdly low relative to the quality of the pitcher you're getting. This is the definition of a plus-EV play.
The Rangers are 6-5 on the season and riding a 2-game win streak, so they're not a dumpster fire by any means. But here's the thing: Seattle is the road favorite in this game. The books see Woo's dominance and have made the Mariners the favorite despite their 4-8 record. That tells you everything about how the market views this pitching matchup. Woo's presence on the mound is enough to override a 4-game deficit in the win-loss column.
MacKenzie Gore gets the ball for Texas on the other side, and he's a fine pitcher. But this isn't about Gore. This is about whether the Rangers lineup can generate enough offense against Woo specifically to push him past 1.5 earned runs. When you're facing a pitcher with a 0.54 WHIP, your margin for error is essentially zero. You need to capitalize on the few baserunners you get, and Woo simply isn't giving those opportunities up. Five hits in 13 innings. That's fewer than one hit every two innings.
The visual says it all. Woo's WHIP isn't just below average. It's less than half the league average. The gap between Woo and a typical MLB pitcher is enormous, and it directly translates to earned runs suppression. Fewer baserunners means fewer opportunities for runs. Fewer opportunities for runs means the under hits. It's the simplest equation in prop betting, and Woo is sitting on the extreme end of the spectrum where the math is overwhelmingly in your favor.
No honest analysis skips the risks. Here's what you need to consider before locking this in.
The biggest risk is simple regression. A 0.54 WHIP is not sustainable over 200 innings. Woo's 2025 WHIP was 0.93, which is where he'll likely settle this year. The question for today isn't whether the 0.54 holds all season. It won't. The question is whether Woo is locked in enough right now, in this moment, to hold Texas under 2 earned runs. Given that his last start was 7 scoreless innings with only 3 baserunners, the answer leans heavily toward yes. Regression is a season-long force. On any given day, a pitcher in the zone stays in the zone.
The risks here are real but manageable. The small sample is the biggest one, but Woo's 2025 All-Star season provides the foundation that tells you this isn't some random journeyman on a hot streak. This is a legitimate ace who has simply been even better than usual to start 2026. The park factor is a slight negative, and Texas being competent is worth noting. But none of these risks are severe enough to negate the core thesis: a pitcher with a 0.54 WHIP at even money is a gift.
This is one of the cleanest earned runs under plays you'll find this week. Bryan Woo has a 1.38 ERA through 13 innings. His 0.54 WHIP ranks 3rd in all of Major League Baseball. He's allowed just 5 hits and 2 earned runs all season. His last start was 7 scoreless innings with only 3 baserunners. He was an All-Star in 2025 with a 2.94 ERA and 198 strikeouts. And you're getting all of this at +100. Even money. No juice.
At +100 odds, you need this to hit just 50% of the time to break even. For a pitcher who has allowed 2 earned runs in 13 innings, that breakeven threshold is laughably low. Compare this to Skubal's -160 line yesterday, where you needed a 61.5% hit rate. Woo has comparable early-season numbers and you're getting him at a significantly better price. The 0.54 WHIP tells you that baserunners are a rare commodity against this pitcher. Five hits in 13 innings. Fifteen strikeouts. His last start was a masterpiece. The Rangers are a decent team, but they're facing a pitcher who is simply not letting people reach base. When a top-3 WHIP pitcher is available at even money on the ER under, you take it every single time. This is the kind of value that doesn't come around often.
Woo doesn't need to throw a gem tonight. He doesn't need to match his 7 scoreless innings from his last start. He just needs to hold Texas to 1 earned run or fewer, which is exactly what he's been doing all season at an absurd rate. Two earned runs in 13 innings is not an accident. It's the product of elite stuff, elite command, and a pitcher who came into 2026 determined to build on his All-Star breakout. At +100, this is the best price you'll get on one of the best pitchers in baseball. Don't let it pass you by.
