Seattle Mariners

Last Monday, the Seattle Mariners defeated the Athletics by outhitting them 9-7. Luis Castillo pitched seven innings of one-run ball, and Andres Munoz recorded his 24th save of the season. Cal Raleigh went 2-for-4 with an RBI single. The Mariners won their fifth game out of 10, but have yet to win consecutive games in that stretch. They are currently three games behind the AL-West leading Houston Astros and hold the middle wild-card spot in the American League. Bryan Woo will be pitching at Sutter Health Park on Wednesday night. The 25-year-old right-hander has an 8-5 record with a 2.91 ERA and 0.95 WHIP in 20 starts this season. He has a successful history against the Athletics, with a 6-0 record and 1.66 ERA in eight career starts. Throughout two meetings this season, Woo has gone 1-0 with a 4.50 ERA against the Athletics.

Oakland Athletics

Last Monday, the Athletics struggled offensively, scoring just one run on seven hits and two walks while going 0-for-4 with runners in scoring position. They also committed an error that cost them a run, contributing to the end of their four-game winning streak. Despite this setback, they had a successful week previously, sweeping the Houston Astros in four games. With an 11.5 game deficit in the playoff race, the Athletics are playing without pressure. On Wednesday, Jeffrey Springs will take the mound for the team. Springs has had a solid season with a 9-7 record, 4.13 ERA, and 1.20 WHIP in 20 starts and two relief appearances. In his last outing against the Astros, he threw six innings of two-run, four-hit ball. Springs has had success against the Mariners in the past, with a 2-0 record and 2.43 ERA in career starts and relief appearances. He is also 1-0 with a 1.64 ERA in two starts against Seattle this season. The current Mariners lineup has had some success against Springs, going 10-for-53 with a double and a home run.

Mariners Likely to Have Upper Hand in Competitive Matchup Against Athletics Based on Bullpen Strength

The upcoming game appears to be highly competitive with both Bryan Woo and Jeffrey Springs having successful track records against their opponents, the Athletics and Mariners, respectively. Notably, both teams' bullpens have performed adequately in the recent 10-day period, with the Mariners posting a 3.82 ERA and 2.64 FIP, and the Athletics recording a 3.67 ERA and 3.47 FIP. Over this timeframe, the Mariners have produced a 97 wRC+ when facing left-handed pitchers, while the Athletics have achieved a 110 wRC+ against right-handed pitchers. Considering these factors, I predict that the Mariners will have the advantage in the upcoming game due to their perceived bullpen depth compared to the Athletics'.
