Rangers vs. Mariners Predictions: Saturday, April 12th

Today’s AL West matchup between the Seattle Mariners and Texas Rangers features a pair of exciting young arms. Bryan Woo and Kumar Rocker both offer plenty of upside and they should combine to anchor a lower-scoring game on Saturday night. 

Woo had a breakout 2024 campaign for Seattle with a 2.89 ERA and 0.90 WHIP. He began this season on a high note with six innings of one-run ball against the Athletics. Despite allowing four runs against the Giants in his second outing, there are some positives to take away. Woo had a 6:1 K:BB ratio in the game and three of the four runs allowed came on one swing (a three-run homer). 

Woo should bounce back at home, where he had a 2.47 ERA with a 25.3% K rate and .186 batting average allowed last season. The right-hander has taken full advantage of Seattle’s pitcher-friendly park. He’ll face a Rangers offense that’s hitting just .193 (30th in MLB) with a .266 wOBA (29th) against righties so far. 

Meanwhile, Texas starter Kumar Rocker can do his part for the under to cash. The rookie pitcher had a shaky season debut with six runs allowed in Cincinnati. Yet, he rebounded with five innings of one-run ball against the Rays last outing. In that start, Rocker threw his sinker a lot more and stayed away from the four-seam fastball. 

Rocker’s raw talent has been well-documented at this point. We’ve yet to see it consistently in the majors, though. He was up-and-down in three MLB starts last year after posting a 1.96 ERA in the minors in 2024. 

Rocker’s last start and the pitch adjustments are encouraging that he can be effective in easier matchups moving forward. That’s the case today in a favorable ballpark in Seattle against a below-average offense. The Mariners are batting .199 on the year (28th) with a .286 wOBA (23rd) as a team. 

 

 

 

Phillies vs. Cardinals Predictions: Saturday, April 12th

Cristopher Sanchez had a breakout season last year for Philly. However, he proved to be a much different pitcher on the road. Sanchez had a 5.02 ERA and 1.66 WHIP on the road compared to a 2.21 ERA and 0.97 WHIP at home. Those are some eye-opening home/road splits for the Phillies’ southpaw. 

Meanwhile, the Cardinals are hitting lefties very well this season. They have a .367 wOBA (fourth in MLB) and .826 OPS (fifth) in the split with a high 15.9% walk rate vs. left-handers (second). It’s a tough spot for Sanchez, who struggled a bit against the Dodgers last time out with four runs allowed on six hits. 

Meanwhile, the Philadelphia offense can get to Cardinals starter Miles Mikolas as well today. Mikolas got rocked last start, allowing nine runs on 11 hits across just 2.2 innings to the Red Sox. The veteran right-hander had a 5.35 ERA last season and is already off to a shaky start to the 2025 campaign. 

Mikolas also struggled to a 6.16 ERA at home last year. Now he faces a dangerous Phillies lineup that’s crushing right-handed pitchers so far. They boast a .357 wOBA (fifth), .807 OPS (sixth), 14.8% walk rate (first), and 16.2% K rate (first) vs. righties this season so far. 

Plus, we have a pair of underperforming bullpens once Sanchez and Mikolas leave the game. St. Louis has a 5.64 ERA as a relief corps while Philadelphia’s relievers have a 4.15 ERA as a unit. All signs point to a higher-scoring contest that gets going early.
