Dodgers left-hander Justin Wrobleski has been elite in his transition back to a starting role this season, posting a 1.50 ERA and 0.97 WHIP through five games. Wrobleski has continued his steady growth entering his third year with Los Angeles and is climbing quickly within an already loaded rotation. The 25-year-old owns a 0.69 ERA in April and has already earned four wins, showing the ability to work deep into games. Wrobleski has attacked the strike zone consistently while generating more weak contact. He made only two starts for the Dodgers last season, but he looks fully comfortable in this expanded role. If this level continues, Wrobleski will remain one of the best waiver wire additions for fantasy managers seeking pitching help.

San Diego Padres right-hander Randy Vasquez has been dominant through five starts this season, posting a 1.88 ERA, 1.08 WHIP, and 30 strikeouts across 28.2 innings. Vasquez has allowed more than one run only once, showing impressive consistency in his third year with San Diego. The 27-year-old logged a 3.84 ERA in 28 games last season, but he appears ready to take another step in 2026. His swing-and-miss profile has improved dramatically, with his K% rising to 26.3 after finishing at 13.7 last year. If this growth continues into May, he could become a key fantasy waiver wire target and an important piece of the Padres rotation.

The New York Yankees have called up outfielder Jasson Dominguez after a dominant start at Triple-A Scranton/Wilkes-Barre. Dominguez hit .306 with an .875 OPS and three home runs in 22 games, earning another opportunity with the first-place Yankees. The 23-year-old has flashed impact tools since debuting in 2023, but he has not yet delivered consistent production in the majors. Dominguez slashed .257/.331/.388 across 123 games last season and was left off the Opening Day roster this year. This promotion gives him a fresh chance to translate his minor league momentum into everyday value. If he starts quickly, Dominguez could secure a meaningful role in a potent Yankees lineup.

Athletics right-hander Jack Perkins is quickly emerging as the club's preferred ninth-inning option after recording saves in each of his last two appearances. Perkins has been one of the early surprises in the Athletics bullpen, posting a 3.18 ERA and 1.15 WHIP through six outings. Scott Barlow entered the season as the likely favorite for save chances, but he blew his lone opportunity and has shifted into more of a setup role with five holds already. Perkins is in his second major league season and is showing the poise and stuff needed for high-leverage work. His recent usage suggests growing trust from the coaching staff as the Athletics sort out late-game roles. Fantasy managers searching for saves should act quickly, as Perkins is trending toward steady closing opportunities moving forward.
