Oakland Athletics

Osvaldo Bido struggled mightily in Wednesday's 12-11 loss to the Rangers, allowing four earned runs on three hits and two walks while striking out four over just 2.2 innings.

Fantasy Impact: This outing ballooned his ERA to an unsightly 13.50 and WHIP to 1.88, which are hardly the numbers fantasy managers dream of. Despite a strong K/9 rate of 13.5, his inability to limit hits and runs severely undermines his fantasy value. The high BABIP of .429 suggests some bad luck, but it's clear that Bido needs to make significant adjustments to be considered a viable fantasy option. His high strikeout rate might keep him on the radar in very deep leagues or formats that heavily reward strikeouts, but most managers should view him with caution until he shows signs of improvement.

Tyler Soderstrom went 2-for-5 with a home run and two RBI in the Athletics' narrow 12-11 defeat to the Rangers.

Fantasy Impact: The young catcher's performance was a bright spot for Oakland, showcasing his power potential with a solid home run. Despite the team's loss, Soderstrom's ability to contribute significantly in just his first game of the season suggests he could be a valuable asset for fantasy teams, especially in leagues that value power-hitting catchers. His high wOBA (.577) indicates strong offensive production, though his high strikeout rate (0.400) and lack of walks could be areas of concern. Fantasy managers should monitor his plate discipline and contact rates closely, but his power stroke could offer considerable upside.

Shea Langeliers went 2-for-5 with a home run and three RBI in the Athletics' 12-11 loss to the Rangers.

Fantasy Impact: The catcher's performance was a bright spot in an otherwise disappointing outcome for Oakland. Langeliers's power continues to be an asset, with his ninth homer of the season contributing significantly to his RBI total, which now stands at 24. Despite a low batting average of .209, his ability to drive in runs and hit for power makes him a valuable asset in fantasy leagues that reward these categories. However, his high strikeout rate and low BABIP suggest potential volatility in his performance, so fantasy managers should temper expectations and consider him a high-risk, high-reward option.

Seth Brown went 1-for-4 with a home run and three RBI in the Athletics' 15-8 loss to the Rangers.

Fantasy Impact: This season, Brown has struggled mightily at the plate, posting a meager .179 batting average with a high strikeout rate. His power stroke in this game could hint at potential improvements, but fantasy managers should remain cautious given his overall performance this year.

Fantasy Impact: Ferguson has posted a 2.40 ERA across 15 innings with 24 strikeouts so far in the minors. He figures to add some depth to the bullpen for Oakland.

Alex Wood delivered a strong performance in Monday's 4-2 loss to the Rangers.

Fantasy Impact: He tossed six innings, allowing just two hits and one walk while striking out three and giving up no earned runs. Despite his solid outing, Wood's season has been less than stellar, marked by a high 5.30 ERA and 1.74 WHIP over eight starts. His performance against the Rangers, however, could be a sign of turning things around, especially considering his ability to limit hits and runs in this outing. Fantasy managers should keep an eye on whether this start is a true turnaround or just a blip in an otherwise disappointing season.
