Peterson will pitch in bulk relief behind opener Tobias Myers in Sunday's game against the Cubs, Abbey Mastracco of the New York Daily News reports.

Myers made 31 starts for the Brewers over the past two seasons but he's maxed out at three innings and 39 pitches over his six relief appearances for the Mets in 2026. While the right-hander might provide more length than a typical opener, Peterson still appears to be in line to handle the larger share of the workload Sunday. Since tossing 5.1 shutout innings in his first start of the season March 28, Peterson has taken losses in each of his last three outings while posting a 8.79 ERA, 1.95 WHIP and 18:8 K:BB across 14.1 innings.

O'Hearn is out of the lineup for Sunday's game against the Rays.

The left-handed-hitting O'Hearn hasn't been a strict platoon player for the Pirates this season, but after he played eight of 13 innings in Saturday's 8-7 loss, he'll get a breather for Sunday's matinee game while southpaw Shane McClanahan toes the rubber for the Rays. Jake Mangum will pick up a start in the outfield in O'Hearn's stead.

Fraley is out of the lineup for Sunday's game against the Pirates, Marc Topkin of the Tampa Bay Times reports.

Even with the Rays facing right-hander Mitch Keller in the series finale, Fraley will cede his spot in right field to Jonny DeLuca. Fraley has recorded hits in five of his last six starts but is still holding down a pedestrian .227/.292/.364 slash line over 48 plate appearances.

The Pirates optioned Sanders to Triple-A Indianapolis on Sunday, Colin Beazley of the Pittsburgh Post-Gazette reports.

The right-hander was called up from Triple-A on Friday and made his season debut Saturday against the Rays, but he'll head back to the minors after surrendering to four runs over two-thirds of an inning. Wilber Dotel will take Sanders' place in Pittsburgh's bullpen.

The Pirates recalled Dotel from Triple-A Indianapolis on Sunday, Colin Beazley of the Pittsburgh Post-Gazette reports.

The 23-year-old has surrendered 10 earned runs with a 13:7 K:BB over 14.1 innings to begin the season with Indianapolis, but he'll get his first opportunity in the major leagues anyway. Dotel was working out of the rotation at Triple-A but will shift to the bullpen to provide some depth for the Pirates after Saturday's 13-inning loss to the Rays.

The Nationals recalled Alvarez from Triple-A Rochester on Sunday.

The left-hander has a 4.66 ERA, 1.20 WHIP and 27:10 K:BB across 19.1 frames in four starts for Rochester and will now get a look in the big-league bullpen. The Nationals are starting PJ Poulin as an opener Sunday before turning to primary pitcher Miles Mikolas, after which Alvarez could be called upon to provide some more length.

Mikolas is scheduled to work in bulk relief behind opening pitcher PJ Poulin in Sunday's game against the Giants, Mark Zuckerman of NatsJournal.com reports.

The Nationals will pair Mikolas with Poulin for a second straight turn through the rotation. After turning in a 12.41 ERA, 2.35 WHIP and 11:7 K:BB in 12.1 innings over his first three starts this season, Mikolas didn't fare dramatically better coming out of the bullpen Tuesday, as the Pirates tagged him for three earned runs on three hits and two walks across 3.1 innings. Despite the favorable matchup against a weak Giants offense, Mikolas hasn't provided reason for fantasy managers to include him in lineups with any level of confidence.

Poulin will serve as the Nationals' opening pitcher for Sunday's game against the Giants, Mark Zuckerman of NatsJournal.com reports.

Poulin will draw his third start of the season as an opener, again working in front of Miles Mikolas. The Nationals rode the Poulin-Mikolas pairing to a win over the Pirates on Tuesday, though the two pitchers combined to allow four earned runs over 4.1 innings. Poulin is unlikely to pitch more than an inning or two Sunday before turning the game over to the veteran right-hander.

The Brewers list Harrison (wrist/knee) as their probable starter for Tuesday's series opener in Detroit.

Harrison had been lined up to make a start this weekend in Miami, but the Brewers ended up pushing the southpaw back in their pitching schedule while he continued to tend to a sore left wrist and knee discomfort coming out of his previous outing April 11. Per MLB.com, Harrison completed a bullpen session Saturday, and with the 24-year-old apparently checking out fine following the workout, he'll be cleared to rejoin the rotation. Milwaukee called up Coleman Crow to make a spot start Friday in Harrison's stead, but Crow has since been optioned back to Triple-A Nashville.

Marquez took a no-decision Saturday against the Angels, allowing no runs on two hits and two walks in 5.2 innings. He struck out eight.

The veteran right-hander put together his longest outing of the year in what was also arguably his finest effort of 2026 so far. He surrendered a season-low two hits while also matching a season high in punchouts. Marquez has worked his way back into fantasy relevance following a couple of tough seasons in Colorado, posting a respectable 3.86 ERA, 1.39 WHIP and 15:6 K:BB over 18.2 innings for the Padres this year. His next start tentatively projects to come versus Arizona.
