Mariners Bring Seven-Game Winning Streak to Baltimore

The Seattle Mariners are one of the hottest teams in the majors, and they arrive in Baltimore looking to extend their winning ways. The three-game series against the Orioles begins Tuesday night at Camden Yards.

Seattle has won seven straight and nine of its last 10, making them one of the most consistent clubs in the league heading into this matchup. Fans looking to stay ahead of the curve can check the latest MLB picks to see how oddsmakers view this red-hot run.

Mariners manager Dan Wilson emphasized the importance of maintaining momentum. “Now it’s time to take it on the road and just continue the momentum,” he said.

Catcher Cal Raleigh, who leads the majors with 45 home runs, has been a key piece of Seattle’s surge. “First thing that pops out is offense playing really well,” Raleigh said. “Guys are getting on base and setting the tone.”

Orioles Seeking Consistency at Home

Baltimore sits in last place in the American League East and has won only two of its last seven games. The Orioles, 28-29 at home, must rediscover their offensive rhythm after producing just 12 hits in their weekend series loss to the Athletics.

Interim manager Tony Mansolino is counting on the pitching staff to keep them competitive. “I hope our starters go seven every night,” Mansolino said. “The reality is that might not happen, which means if you’re in the bullpen, you’re going to pitch.”

With Monday serving as an off-day for both clubs, Baltimore’s bullpen had a brief chance to reset before this critical series. Those tracking matchups can review in-depth MLB previews for more breakdowns.

Kirby vs. Kremer: Pitching Matchup

Seattle hands the ball to right-hander George Kirby (7-5, 4.04 ERA), who has won three consecutive starts. Since the end of June, he’s 6-1 with a 2.83 ERA. However, Baltimore tagged him for two runs on eight hits over five innings in a June 3 meeting. In seven career starts against the Orioles, Kirby owns a 1-5 record and a 3.80 ERA.

Baltimore counters with Dean Kremer (8-8, 4.35 ERA), who has allowed 12 runs in 17 innings over his last three outings. Kremer is 1-0 with a 2.57 ERA in five career starts against Seattle, with 25 strikeouts in 28 innings.

Orioles Looking for Veteran Leadership

Baltimore will also lean on its limited veteran presence. First baseman Ryan Mountcastle returned Friday after a 10-week IL stint and promptly hit his first home run since April 30.

“He just got back and I know he’s looking around right now and he’s kind of coming to the same conclusion that he’s one of the guys now, he’s one of the leaders in that clubhouse,” Mansolino said. “It’s so good to have him back.”

Series Outlook

While Baltimore’s offense remains a question mark, the Orioles’ earlier sweep of Seattle in late May proves they can match up well against this Mariners team. However, given Seattle’s current form, the Orioles will need strong pitching and timely hitting to halt the visitors’ momentum.
