Colorado Rockies infielder Willi Castro (hand) is back in the starting lineup for Sunday's series finale against the division-rival Los Angeles Dodgers and right-hander Roki Sasaki at Coors Field, according to MLB.com. Castro is starting at shortstop and will hit seventh with regular shortstop Ezequiel Tovar getting the day off. Edouard Julien is at second base and is batting leadoff for Colorado. Castro is returning to the starting nine for the first time since suffering a right-hand contusion when he was hit by a pitch on Wednesday. The 28-year-old switch-hitting Puerto Rican outfielder had mostly been playing at second in his first year with the Rockies to begin the 2026 season, but he might be relegated to more of a bench role soon if he doesn't pick things up offensively. Going into Sunday's clash with L.A., Castro has gone just 12-for-56 (.214) with a homer, eight RBI, eight runs scored, and a stolen base. He has never faced Sasaki in his MLB career.

Toronto Blue Jays outfielder Daulton Varsho (knee) remains out of the starting lineup for Sunday's series finale on the road against the Arizona Diamondbacks, according to MLB.com. Myles Straw will make the start in center field for Toronto and will bat eighth against D-backs right-hander Ryne Nelson. Varsho will miss a second straight game after being pulled from Friday's series opener early at Chase Field due to left-knee discomfort. He's considered day-to-day for now, but fantasy managers will want to check back on Monday for an update on his status before the team's series opener on Monday night in Anaheim against the Los Angeles Angels. Varsho played only 71 games in the 2025 regular season due to injuries. In 19 games so far in 2026, he has slashed .262/.333/.462 with three home runs, seven RBI, and eight runs scored. Straw, who is more of a defensive asset for the Jays than an offensive one, should see most of the playing time in center for however long Varsho is out.

The Houston Astros announced on Sunday that they placed outfielder Joey Loperfido (quadriceps) on the 10-day injured list (retroactive to April 18) with a right-quad muscle strain. In a corresponding move, the Astros recalled right-hander Jayden Murray from Triple-A Sugar Land. Loperfido injured his quad during Friday's series opener against the St. Louis Cardinals and was held out of action on Saturday. It's unclear if the 26-year-old left-handed-hitting outfielder will be ready to come off the IL in late April when he's eligible to be activated. In the meantime, young outfielder Brice Matthews figures to see more playing time going forward in Houston's outfield. Lopefido, a former seventh-round selection out of Duke in 2021, is still searching for his first long ball of the 2026 season. Through his first 20 games played, he's gone 15-for-58 (.259) with five doubles, six RBI, seven runs scored, a stolen base, six walks, and 19 strikeouts for Houston.

San Francisco Giants infielder Casey Schmitt has been one of the surprise success stories of the early portion of the 2026 season. Entering play on Sunday, Schmitt was hitting .317/.369/.517 with two home runs, seven RBI, seven runs scored, and one stolen base. The 27-year-old's strong production is supported by his underlying metrics, as he's posted above-average barrel (11.4%) and hard-hit (52.3%) rates. Schmitt has also moved into the heart of the Giants' lineup, which should allow him to rack up counting stats more consistently. While Schmitt has played exclusively at first base and designated hitter in 2026, he's capable of playing every infield spot and still offers fantasy managers multi-positional eligibility. As a cheap depth piece with some upside, Schmitt could be worth targeting on the waiver wire.
