The Mariners and Guardians open a weekend three‑game set tonight in Cleveland. The Guardians are home after salvaging the final game of their three-game series against the White Sox. Cleveland won, 4-3, in ten innings last night. Cade Smith gave up solo home runs to B Montgomery and Randal Grichuk to blow a 3-1 lead last night but Cleveland prevailed in the tenth thanks to a Kahlil Watson single that scored Petey Halpin. The Mariners dropped their second straight in Pittsburgh last night. Bubba Chandler was elusive last night, limiting the Mariners to one run over 5.1 innings despite giving up five hits and walking three hitters. Seattle was 1-10 with runners in scoring position as they fell back to .500 for the season (41-41). The Mariners have scored three or fewer runs in 11 straight games.
It is not surprising that the season series between Seattle and Cleveland is tied 2–2 heading into tonight’s matchup. Both teams have shown similar statistical profiles on the mound and at the plate. Seattle owns a .231 team batting average with 100 home runs, while Cleveland sits at .228 with 75 homers. Seattle carries a 3.71 ERA (5th in MLB), and Cleveland follows closely with a 3.79 ERA (6th).
Tonight’s pitching matchup features Luis Castillo for Seattle and Joey Cantillo for Cleveland. Castillo enters at 2–6 with a 5.22 ERA, 69 strikeouts, and a 1.40 WHIP across 70.2 innings. Cantillo’s season has been far more positive with an overall record of 6–3, a 4.05 ERA, 76 strikeouts, and an identical 1.40 WHIP over 80 innings.
Seattle’s hottest hitter over the last week plus is Dominic Canzone. The fact he is considered a hot hitter despite going just 8‑for‑30 in his last 10 games is a testament to just how bad Seattle has been at the plate. Julio Rodríguez is 3-9 over the last two games but is hitting a mere .198 in June. Cleveland’s Travis Bazzana is 11‑for‑36 with two doubles, three home runs, and seven RBI over his last 10 games.
