Seattle vs Oakland Stats

Seattle Mariners

The Seattle Mariners have had a remarkable turnaround after a slow start to the season, winning six consecutive games before visiting the Texas Rangers in search of their seventh straight victory. Their offense has been a pleasant surprise, hitting .248/.343/.428 with 43 doubles and 49 home runs in the first 32 games of the season. Bryce Miller is set to pitch on Monday night with a 2-3 record and a 3.52 ERA in six starts this season. Overall, the Mariners are ranked 3rd in offense, 14th in defense, and have a 20-12 record this season.

Oakland Athletics Analysis

The Oakland Athletics have been performing well in recent weeks, winning their last few series including against the Texas Rangers and Chicago White Sox. They have scored 26 runs in their last six games while yielding 27 runs, notably giving up 15 runs in a heavy defeat against the Rangers. The Athletics have a .253/.314/.423 slash line with 51 doubles and 45 home runs in 34 games. Luis Severino is expected to start for the A's with a 1-3 record, 3.30 ERA, and 1.17 WHIP in seven starts this season.

Severino vs. Miller: Pitching Matchup Key in Mariners vs. Athletics Showdown

Luis Severino has shown strong performances in his recent outings, giving up six earned runs on 21 hits and six walks over his last four starts spanning 24.2 innings. Although he performed well against the Mariners on Opening Day, the team has been particularly successful against right-handed pitchers in the past 10 days. On the other hand, the Athletics have had less success against right-handed pitchers during the same time frame. Considering these factors, I believe Seattle's potent offense will have an impact on the outcome. Bryce Miller has struggled with control, evidenced by 19 walks in 30.2 innings pitched, but has had solid performances in two of his last three starts. Current A's hitters have had limited success against Miller, while the current Mariners have performed better against Severino.
