Urena will start Sunday's game against the Padres, Jeff Fletcher of The Orange County Register reports.

The right-hander was called up from Triple-A Salt Lake on Saturday and will fill the Halos' open rotation spot, pushing back Reid Detmers to pitch Monday versus the Blue Jays. Urena made two appearances for Anaheim in the opening days of the season and gave up six runs (none earned) on five hits and three walks across 1.2 innings. He covered five frames during his last start for Salt Lake and should be able to handle a typical starting workload.

Detmers is no longer scheduled to start Sunday's game against the Padres and will instead take the hill for Monday's game versus the Blue Jays in Anaheim, Rhett Bollinger of MLB.com reports.

Rather than waiting until the upcoming week to break in a new fifth starter, the Angels will have Walbert Urena enter the rotation for Sunday's series finale while moving each of their other four starters back a day. Detmers tentatively lines up for two starts next week, with his second turn set to come next Sunday in Kansas City.

Mets manager Carlos Mendoza indicated that Peterson will pitch in bulk relief behind opening pitcher 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 and has maxed out at three innings over his six relief appearances for the Mets in 2026, so while he'll likely provide more length than the typical opener, Peterson appears in line to handle the larger share of the pitching workload Sunday. The Mets are hopeful that by using the left-handed Peterson in relief, the Cubs will have to deploy a more balanced lineup that isn't stacked with right-handed bats at the top of the order. 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 collective 8.79 ERA, 1.95 WHIP and 18:8 K:BB across 14.1 innings during that stretch.

The Astros recalled Murray from Triple-A Sugar Land on Sunday.

The right-hander was optioned to Sugar Land last week but will rejoin the Astros with Joey Loperfido (quadriceps) landing on the injured list. Murray allowed two runs over two innings with a 3:3 K:BB in his lone appearance for Houston this season

Valdez's scheduled start Sunday against the Red Sox has been pushed back three hours due to rain, Chris Cotillo of MassLive.com reports.

An extended period of rain is forecasted for Boston from midday into the afternoon, making a scheduled 1:35 pm start time unlikely. Valdez will square off against Red Sox lefty Garrett Crochet.

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 to begin the season with Indianapolis, but he'll now get his first opportunity in the major leagues. 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 Royals optioned Spence to Triple-A Omaha on Sunday.

Spence wasn't going to be available for at least a few days after he yielded six earned runs on four hits and five walks while covering four innings and tossing 84 pitches in long relief during Saturday's 13-4 loss to the Yankees, so Kansas City will send him to the minors in exchange for a fresh arm. Mason Black was recalled from Triple-A Omaha in a corresponding move and will give the Royals another right-handed arm capable of covering multiple innings out of the bullpen.

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, as the former had previously pitched behind the latter in Tuesday's 5-4 win over the Pirates. After turning in a 12.41 ERA, 2.35 WHIP and 11:7 K:BB in 12.1 innings over his three starts to begin the season, Mikolas didn't fare dramatically better coming out of the bullpen, 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.

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, also matching a season high in punchouts. Marquez has worked his way back into fantasy relevance following a couple of tough recent 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.
