Seminaris

Seminaris spent the 2026 season in the Phillies’ organization where he posted a 4.03 ERA, 1.22 WHIP and a 162/30 K/BB ratio over 138 1/3 innings of work in 26 starts. He’ll add extra rotation depth for the A’s and it wouldn’t be surprising to see him finally break through and make his MLB debut at some point during the 2027 season.

The 26-year-old southpaw was originally a fifth-round pick by the Angels from the 2020 draft class. He spent the last two seasons in the Brewers’ organization where in 2024 he registered an uninspiring 6.15 ERA, 1.63 WHIP and a 73/23 K/BB ratio over 74 2/3 innings at Double-A Biloxi. He has the ability to work out of the rotation or the bullpen and will give the M’s some added pitching depth.

The southpaw limited the Glendale Desert Dogs to one hit over four scoreless innings Saturday night in Glendale. The 24-year-old was a fifth-round draft pick by the Angels in 2020 and acquired by the Brewers in the Hunter Renfroe deal last fall. The soft-tossing lefty struggled with command over the past two seasons, which is uncharacteristic for him as he was known for his command while at Long Beach State. If he gets back on track, he projects to be a backend starter, but it is more likely that he will end up in a relief role.

Of the three arms that the Brewers received in this deal, Seminaris is the only one that has yet to make his big league debut. The 24-year-old southpaw was a fifth round pick by the Angels in the 2020 draft. In 2022, he compiled a 3.54 ERA, 1.43 WHIP and 97/38 K/BB ratio over 101 2/3 innings in 24 appearances (21 starts) across three minor league levels -- finishing up with nine starts at Triple-A Salt Lake. He adds starting pitching depth for the Brewers.

Seminaris was the Angels’ fifth-round pick this June after previously pitching for Long Beach State. The left-handed hurler posted a shiny ERA of 1.23 in four appearances before the cancelation of the college baseball season. In the long-term, he projects as a backend starter with a possibility of moving to relief as he moves up the ranks.
