Pitching Matchup
Seattle Mariners – Bryce Miller
Miller is 4-2 with a 1.71 ERA and an outstanding 0.66 WHIP across 52.2 innings this season. He has allowed only 30 hits while striking out 62 batters and walking just five. Miller has been one of Seattle's most reliable starters and enters this matchup in outstanding form.
Miami Marlins – TBD
Miami had not announced a starting pitcher at the time of publication. Regardless of who gets the assignment, the Marlins will look to continue receiving quality work from a staff that ranks 11th in MLB in ERA and has supported the club's recent four-win stretch over its last five games.
Seattle Mariners vs. Miami Marlins Game Pick
- Seattle Mariners
Bryce Miller gives Seattle a significant advantage on the mound. His 1.71 ERA and 0.66 WHIP are among the best marks in baseball, while Miami has yet to announce its starter. The Mariners continue to rely on elite pitching, and Miller should be able to slow down a Marlins lineup that has been productive recently. Seattle has the clear edge in the pitching matchup, making the Mariners the play.
Seattle Mariners vs. Miami Marlins Over/Under Pick
- Under
Seattle's pitching staff ranks fourth in MLB in ERA, and Miller has been dominant throughout the season. Although Miami has been swinging the bats well lately, the Mariners consistently keep opponents from producing big innings. With an elite starter on the mound for Seattle and an important series finale between two winning clubs, expect scoring to cash under the total.
