Seattle Mariners starting pitcher Luis Castillo (3-2) dominated the Miami Marlins on Saturday, tossing six scoreless innings in a 14-0 win. Castillo allowed just one hit and two walks while punching out five. The 32-year-old was coming off two outings where he allowed 23 baserunners in just 9 IP, so a start like this one was sorely needed. He improves to (3-2) with a 3.62 ERA, 1.39 WHIP, and 28 strikeouts in 32 IP. Fantasy managers will hope he can build off this start next Saturday when he is projected to face the Texas Rangers on the road.

Boston Red Sox designated hitter Rafael Devers went 3-for-7 with a homer, a double, two walks, two RBI, and two additional runs scored in Saturday's doubleheader against the Cleveland Guardians. Devers is now hitting .210 with a .722 OPS, 18 runs, three homers, and 16 RBI. So far, it has been a disappointing season for the 28-year-old star, who came into Saturday without a hit in his last five games (15 at-bats). The good news for fantasy managers is that Devers is severely underperforming his expected stats and will likely regress to his usual self soon, so hold steady and don't sell low.

Arizona Diamondbacks third baseman Eugenio Suarez became the 19th player in MLB history to hit four homers in a game on Saturday. Suarez could not be stopped in this one, hitting a homer in each of his plate appearances and collecting five RBI. Unfortunately for him and the D-backs, they still ended up losing 8-7 to the Atlanta Braves. The 33-year-old is now hitting .202 with 17 runs, 10 homers, 20 RBI, and a stolen base. After a massive hot streak to start the season, Suarez had been extremely cold coming into this game, hitting only one homer over his last 21 games and seeing his OPS drop from 1.492 to .690 in that stretch. Fantasy managers will hope that this game ignites him into another heater.

Seattle Mariners designated hitter/third baseman Jorge Polanco went 2-for-4 with two home runs, a walk, and an additional run scored in Saturday's 14-0 win over the Miami Marlins. Polanco has four homers in his last four games as he continues to play some of the best ball of his career. The 31-year-old has been studly for the M's this year, hitting .354 with a 1.085 OPS, 10 runs, seven homers, 18 RBI, and a stolen base in 65 at-bats. The only issue for Polanco right now is that he isn't playing every day, but at this point, he should still be rostered in most fantasy leagues, at least until he cools off.

Los Angeles Angels shortstop Zach Neto showed off his power-speed combo on Saturday, going 3-for-4 with a homer and three steals in a 5-1 loss to the Minnesota Twins. Neto is now hitting .300 with a .990 OPS, five runs, three homers, five RBI, and three steals in 30 at-bats. The 24-year-old is only a week into his season as he returned from shoulder surgery on April 18, but so far, so good. He popped some impressive numbers last season, including 23 homers and 30 steals, and if the Angels' shortstop can build on those, he should be a stud in fantasy. Neto is still available in some leagues but should be rostered in all leagues now.
