Mariners vs Rangers Preview
Seattle Mariners Betting Preview
It's been a slow start to the year for the Mariners, who enter this important divisional series with a record of 4-6. It's probably still early to be overly worried about a side that went to the ALCS last season, though, and they have already lost a number of tight games that could have gone either way.
As expected, Seattle's pitching has been rock solid thus far, as it holds a team ERA of 2.72 and leads the league with an xERA of 2.46. The bullpen holds an ERA of 2.32, after generally being regarded as the second-best unit in baseball entering the year.
Logan Gilbert's ugly start to the year has been the team's biggest concern from a pitching perspective, as after earning an Opening Day start after pitching to a 3.44 ERA across 131 innings, he's struggled to an ERA of 6.75 thus far, and the Mariners have lost both of those outings.
Gilbert's underlying profile still looks quite strong though, and nothing under the hood suggests his poor start is indicative that he will be a bust this season. His average fastball velocity is down a hair compared to last season, but his Stuff+ rating of 107 and Pitching+ rating of 112 are both up relative to last year.
He holds an xERA of 2.30, an xFIP of 3.55, and a K-rate of 29.5%. Those are all strong indicators, but stranding just 51.5% of base-runners and suffering from a BABIP of .407 have led to some horrid results where it counts.
Seattle ranks 16th with an offensive wRC+ of 92 and ranks 28th with a slug rate of .329. The struggles of the team's expected top bats are the greatest reason for the slow start offensively, as Julio Rodriguez, Cal Raleigh and Josh Naylor hold a combined slugging average of .154.
Raleigh's struggles may be the most concerning, as after a horrible showing for Team USA at the WBC, Raleigh has struck-out 46.5% of the time and holds a hard-hit rate of 11.1%.
Texas Rangers Betting Preview
Texas struggled to an offensive wRC+ of 92 last season, which led to an absence from the postseason despite its pitching staff managing a league-leading ERA of 3.49. In an attempt to bolster the offense, the team brought in veterans Brandon Nimmo and Andrew McCutchen, while greater health from its top projected batters could offer an even greater impact in terms of year-over-year improvements.
To this point Nimmo and McCutchen have been excellent, but struggles at the plate from Wyatt Langford, Evan Carter and Josh Jung have led to middling results. The Rangers hold a wRC+ of 99 and have struck out 26.4% of the time. They rank 22nd in xwOBA and hold the second worst BB/K ratio in baseball.
Jacob DeGrom struggled in his first outing of the season versus the Baltimore Orioles, as the future Hall of Famer allowed six hits and three earned runs across four and two-thirds. As with his counterpart in Gilbert, though, DeGrom's underlying metrics suggest the outing may not be an accurate indication of how the rest of the season will go.
DeGrom held a Stuff+ rating of 114 and an average fastball velocity of 97.6. It felt like a vintage performance from DeGrom early on, and he did strike out seven batters while issuing zero walks but ultimately finished with a poor stat line after allowing an untimely two-run double to Gunnar Henderson in the fifth inning, as well as a home run to Pete Alonso.
The Rangers bullpen has pitched to a 2.04 ERA so far this season, after finishing with a fifth-ranked ERA of 3.62 last season. It still projects as a weakness relative to the Mariners unit, but should be a fairly effective unit this season.
Mariners vs Rangers Picks
While DeGrom and Gilbert have not yet combined for one quality start, they are obviously two well-proven arms that were expected to be among the AL's best starters entering the year.
Neither of the two have offered concerns in terms of velocity or quality of stuff thus far this season, and their struggles amid a tiny sample size likely are not indicative of anything overly meaningful.
Both offenses are likely better than we have seen thus far, which is a concern relative to bets on the under, but a total of 7.5 still seems high with two projected aces facing off at baseball's second most pitcher friendly ballpark.
Seattle's bullpen has been excellent thus far as expected, while for a second consecutive season the Rangers relief staff is overachieving expectations in the early going.
At -120 or better, there looks to be value in backing this matchup to come in under a total of 7.5 runs.
Pick: Under 7.5 Runs (-115; Play to -120)
