START BOTH START BENCH BOTH BN

Includes Detailed Projections

Outlook Zack Gelof

Zack Gelof is white-hot during a massive hitting streak, making him a must-start fantasy option.

Zack Gelof is in the midst of an incredible stretch, batting .367 with five home runs, 17 runs scored, and two stolen bases over his last 12 games. The second-place Athletics are leaning heavily on his hot bat, especially with key outfielder Brent Rooker currently sidelined on the injured list. Gelof has firmly established himself as the everyday starter at third base and is carrying the team's offense.

While Gelof's recent power surge is elite, a regression is likely on the horizon. His outstanding 20-game hitting streak has been fueled by an unsustainable .481 BABIP while still carrying a high 27% strikeout rate, which is reminiscent of his career .211 batting average from 2024. Our models project a .222 average with eight home runs over his remaining 144 projected at-bats, suggesting managers should enjoy this peak but be prepared for a cooldown.

The Athletics head out for a six-game road trip against the Giants and Angels. Gelof will face several highly exploitable starters, including Tyler Mahle and his 6.04 ERA, alongside Robbie Ray and Sam Aldegheri, who both carry ERAs above 4.50. Given his current momentum and these excellent matchups, lock him into your lineups as a confident Start.

Includes Detailed Projections

Outlook Rafael Devers

Rafael Devers shows signs of life during a tough stretch for the fourth-place Giants.

Devers remains locked in as the everyday first baseman for the fourth-place Giants, who are currently sliding on a three-game losing streak. While he has hit just .216 over his last 14 days, he showed signs of life over his last five games by batting .286 with a home run and a strong .444 on-base percentage. He remains fully healthy and secure in his middle-of-the-order role despite a wave of injuries hitting the Giants' roster.

His current .237 season average is a clear drop from his stellar career baselines, but our models project him to bounce back toward a .258 average with a projected 20 home runs. The underlying power remains solid, as evidenced by his 11 doubles and four home runs over his last 30 days. Fantasy managers should remain patient with the slugger, as his quality of contact suggests a positive correction is on the horizon.

The Giants play six home games this week, featuring highly exploitable matchups against Oakland starters Aaron Civale (4.91 ERA) and Jeffrey Springs (5.55 ERA), though he must also face Atlanta ace Chris Sale (2.14 ERA). With six games on tap and plenty of run-producing opportunities, he is a must-play option. Weekly Verdict: Start.
