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.
According to the team, the Seattle Mariners have acquired right-handed pitcher Will Klein from the Athletics in exchange for international slot money. Klein was designated for assignment on Friday but will now take his talents to Seattle. Before the trade, Klein was ranked as the No.16 best prospect in the A's system. He logged only seven 1/3 innings at the major league level and allowed nine earned runs. Across 78 innings at Triple-A, the former fifth-round selection has posted a 4.62 ERA and a .164 WHIP. 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.
According to the team, the Athletics have designated right-handed pitcher Will Klein for assignment. This transaction opened the roster spot for right-handed pitcher Jose Leclerc, who the team signed earlier on Friday. Klein was considered the No.16 best prospect on the team before being designated for assignment. The 25-year-old made his big league debut last summer but struggled as he allowed nine earned runs across his first seven 1/3 frames of work. However, he did strike out seven batters. Across 43 innings at the Triple-A level last summer, Klein posted a 3.77 ERA and a 1.43 WHI. He struck out 43 batters but struggled with his command as he served up 32 walks. If Klein finds a suitor, he will likely open the campaign at the Triple-A level.
