Mariners End Skid With Monday Win

The Seattle Mariners had their troubles with the sad sack Los Angeles Angels, having dropped the first three games of their four-game series. Monday was a different story, with Seattle dominant in a 9-1 victory behind the hot bat of Carlos Santana’s two homers.

“My wife told me, ‘Like, I think if you don’t get a home run you don’t love your mom.’ I said, ‘OK, I love my mom,'” Santana said after Monday’s win, which came on his mother’s birthday. “That’s a lot of love right there.”

Santana also drove in five runs in the contest, and has seven home runs in the last nine games. The 36-year-old is batting just .186 since coming to the Mariners in a mid-season trade (Kansas City), but has six doubles, 15 homers, 36 RBIs and 29 runs scored in 64 games with Seattle.

Righthander Luis Castillo gets the start for Tuesday’s contest, his eighth with Seattle since coming to the team in a deadline deal (Cincinnati). Castillo is 3-1 with a 2.37 ERA with the Mariners, striking out 60 in 49⅓ innings. He’s coming off a win over the San Diego Padres last Wednesday (six scoreless innings, four hits, nine strikeouts, one walk).

Athletics Can’t Score

The Oakland Athletics have had one of the worst scoring teams in baseball this season, and that continued against the Houston Astros. Oakland managed just four runs in losing three-of- four, and were shut out Friday.

First baseman Dermis Garcia drove in the only two Oakland runs in Sunday’s loss with a double. Garcia is batting .254 with five doubles, four home runs, 17 RBIs and nine runs scored in 25 games in his rookie season

Lefthander JP Sears gets the start for the series opener. Sears is 5-2 with a 3.90 ERA in nine (14 appearances) with Oakland and the New York Yankees this season, striking out 36 in 55⅓ innings. Sears struggled in his last two, going a total of six innings while surrendering 11 earned runs on 15 hits, including three home runs.

Mariners vs Athletics Head-To-Head

The Seattle Mariners have gone 8-5 against the Oakland Athletics this season. Seattle is going for their second straight season series win after taking 15-of-19 games in 2021.

Playing at Oakland Coliseum has not been a problem, either. Seattle is 12-3 at the venue since the beginning of the 2021 campaign. A look at the MLB lines for Tuesday’s series expects that success to continue, with the Mariners favored to come away with the victory.
