The Philadelphia Phillies have made a crucial bullpen adjustment by promoting Seth Johnson, their No. 12 prospect, back to the majors, leading to the designation of José Ruiz for assignment. The Atlanta Braves claimed Ruiz off waivers, hoping to rejuvenate the right-hander's performance after a shaky start to the season. Ruiz showcased promise last year with a 3.71 ERA and 52 strikeouts in 51 innings, but he's struggled this spring with an ERA nearing 5 and a recent outing against the Milwaukee Brewers that saw him concede five runs.

Ruiz now joins a Braves bullpen that has faced its own challenges this season, reflected in their 3.83 ERA. The Braves have previously integrated former Phillies, including Hector Neris and Enyel De Los Santos, into their ranks. If Ruiz can find his form, he could become a significant asset, especially against his former team, as the NL East race remains tight. The Phillies will need to adjust to this new dynamic as the season progresses and their division lead remains in flux.
