The Angels have officially announced their previously-reported deal with right-hander Robert Stephenson. First baseman/outfielder Alfonso Rivas has been designated for assignment in a corresponding move, per Jeff Fletcher of the Orange County Register.
Rivas, 27, has never appeared in a game as an Angel, having just been claimed off waivers a month ago. Over the past three years, he has been given 459 plate appearances in the majors between the Cubs, Padres and Pirates. He struck out in 30.3% of those and produced a batting line of .243/.324/.349, leading to a wRC+ of 90.
The production at Triple-A has been far more impressive. In 499 trips to the plate at that level over the past three years, he’s hit 14 home runs and paired a 15.6% walk rate with a 21.1% strikeout rate. His combined slash line of .307/.423/.483 translates to a wRC+ of 137. Defensively, he’s been mostly at first base but has also seen some time in the outfield corners.
Since the season ended, he’s been on the waiver carousel. He was claimed off waivers by the Guardians and then the Angels and may end up changing teams yet again. The Halos will now have one week to trade him or pass him through waivers. Despite the tepid major league production, the work in the minors is likely strong enough for him to get a shot with another club. He still has one option remaining and won’t even need to be guaranteed an active roster spot by a club that acquires him.
