Team Recent Performance

Texas Rangers

Things have not been smooth for the Texas Rangers lately. Over their last five games, they have gone 3-2, showing at times how good their offense can be while at other times maintaining sporadicity against the spread. They had good wins over the Angels and Braves, including an easy 8-1 demolition of Atlanta and a stronger 6-3 win in LA, both winning on the -1.5 line. Two losses in three games against the Angels hurt the defense, with both losses sailing over the total and failing to cover the spread. Thus, with the four overs in the last five games, a sudden burst of a run-scoring offense can be matched with some truly shoddy pitching. 

Seattle Mariners

Seattle Mariners concluded their five-game road trip, going 2-3 in a combination of great pitching and weak offense. Their two victories, a 3-1 win against the Athletics and a 7-2 thrashing of the Angels, saw them cover the -1.5 spread, showing how dominating they are when on. Unfortunately, in the three losses that included back-to-back defeats against Oakland, they did not cover the spread. Offensively, the Mariners leaned under the total in four of the five contests, with the exception of the July 26th win in Los Angeles, which went over. It encapsulates an erratic offense that became quite dependable when backstopped by solid pitching.

Team Head-to-Head Matchup

The Mariners outclass the Rangers with regard to offensive production, averaging 5.3 runs per game to their 3.5. They also lead in per game hits (9.7 to 7.5) and have fewer strikeouts than Texas (6.7 to 9.0). By a tiny margin, Texas edges Seattle in walks, but the difference is negligible. The teams are nearly even when it comes to total – each of them has posted a record of 7-3 to the over in the last 10 games, which indicates a tendency toward scoring in numbers in recent games. In general, it is Seattle’s more consistent contact and ability to score that put it in this fight on the head-to-head side of the equation as a potential offense.

Betting Trends

Texas Rangers

With a recent streak of 3-2 against the spread, the Texas Rangers have been comparatively profitable, although they remain below .500 on the road this season at 26-29 against the spread. On the offensive side, trends have leaned heavily toward the over, with four of the last five games going above the total. This recent pattern notwithstanding, the Rangers have surprisingly gone over in only 18 of their last 54 home games, suggesting they tend to score less at Globe Life Field. This discrepancy beefs up a team that may be heating up now but remains erratic at home.

Seattle Mariners

They have not been the best spread coverers lately. Out of their last five games, they won only 2 and lost 3s. Against atypical venues, the Mariners have a dismal 24 wins against 33 losses. Offensively, they have almost continued to trend under the total in their last five games, as only one of those contests goes over. Broadly, however, there is a fair even trend at home, with 25 overs among 52 recent games. This mixed performance in betting shows a definite inconsistency in scoring output and covering spreads, especially for this team while on the road.
