Will Klein DVOA, Advanced Stats, & Fantasy Rankings

The Seattle Mariners have optioned right-handed pitcher Will Klein to Triple-A Tacoma earlier on Friday. The Mariners acquired Klein from the Athletics earlier in the winter. During spring training, Klein has logged five innings and tallied eight strikeouts with three walks. He has allowed five hits with two earned runs. Last summer, the 25-year-old made his MLB debut with the Kansas City Royals before being shipped to Oakland. Across 7 1/3 total frames, he allowed nine earned runs while holding a 6:7 BB:K. At the Triple-A level, the Eastern Illinois product logged 43 innings of relief and posted a 3.77 ERA with a 1.46 WHIP. He tallied nine saves but held an underwhelming 32:43 BB:K. When he returns to the big leagues, fantasy managers should expect him to earn a low-leverage role in the Seattle bullpen, which will not make him viable in any fantasy format.

He struck out an impressive 92 batters but allowed a hefty 57 walks. Klein will likely compete for a spot on the Opening Day roster but should be expected to spend most of the 2025 at Triple-A to continue his development.
