In this article, we will formulate a Mariners vs Rangers prediction for this MLB game on Saturday, May 3, at Globe Life Field in Arlington, Texas. Let’s take a look at the prediction for this MLB matchup.

Seattle Mariners Betting Preview

The Seattle Mariners (19-12, 7-6 Away) are playing their best baseball of the season after securing five consecutive wins for the first time this year. The Mariners won the series against the Marlins, swept the Angels in a two-game series, and opened the current one against the Rangers with a massive 13-1 win. Cal Raleight blasted a grand slam and led the team with five RBI as Seattle scored a season-high 13 runs. Bryan Woo got the win after allowing no runs on one hit with eight strikeouts and no walks over 6.1 innings of work.

This year, the Mariners average 5.07 runs per game (6th in the MLB) on a .241/.339/.415 triple-slash. When it comes to pitching, the Mariners’ staff has a 3.74 ERA (12th) and 1.30 WHIP (11th). Jorge Polanco leads the Mariners with a .387 batting average, nine home runs, and 25 RBI this season.

Luis Castillo will take the mound for the Mariners on Saturday. The 32-year-old right-hander has a 3-2 record in six starts this year with a 3.62 ERA and 1.39 WHIP in 32.1 innings.

Texas Rangers Betting Preview

The Texas Rangers (16-17, 11-7 Home), unlike the Mariners, are going through their worst stretch of the season. Texas lost six of the previous seven games and is on a three-game losing skid. The Rangers lost four straight series, including two to the Athletics, and scored just two runs in total in the last three games. Jack Leiter took the loss against Seattle after allowing six runs on eight hits with two strikeouts and two walks in 4.1 innings.

This season, the Rangers average 3.22 runs per game (30th in the MLB) on a .229/.285/.367 slash line. Regarding pitching, the Rangers’ staff has a 3.26 ERA (6th) and 1.14 WHIP (4th). Adolis Garcia leads the Rangers with a .214 batting average, four home runs, and 15 RBI this season.

The projected starting pitcher for the Rangers is Patrick Corbin, who is 2-1 in four starts this season, with a 3.79 ERA and 1.58 WHIP in 19.0 innings.

Mariners vs Rangers Prediction

The Mariners won nine of the previous ten H2H encounters, including the last four, all this season. Seattle didn't allow more than three runs in those four H2Hs this year, and I am backing the Mariners to limit the Rangers again and not allow them more than three runs. Luis Castillo faced the Rangers twice last year and posted a 3.00 ERA in 12.0 innings. He allowed a .266 BA in 79 at-bats against Texas in his career. Patrick Corbin, on the other hand, registered a 4.50 ERA in 6.0 innings against Seattle last year, and I doubt he will last more than four or five innings here. I am going with the Mariners to get another win.
