Baltimore Orioles outfielder Colton Cowser (thumb) was able to take live batting practice on Saturday. Cowser has been sidelined since late March due to a fractured left thumb. However, seeing him increase his baseball activities is a positive sign. If Cowser continues to progress well, he could be cleared to embark on a rehab assignment in the coming weeks. Last summer, the 25-year-old appeared in a career-high 135 games with the Orioles. Across this stint, he held a .242/.321/.447 slash line with 24 doubles, 24 home runs, and nine stolen bases. When Cowser returns to action, he should have an everyday role in left field. While he remains out, fantasy managers should expect Ramon Laureano, Heston Kjerstad, and Tyler O'Neill to see most of the opportunities in left field.

Baltimore Orioles first baseman Ryan Mountcastle is not in Saturday's lineup when the Orioles continue a series against the Washington Nationals. Mountcastle has started in each of the past 18 games. Fantasy managers should expect the 28-year-old to return to the starting nine on Sunday. Over his last 18 contests, Mountcastle has posted a .239/.263/.366 slash line with six doubles, one home run, and nine RBI. During this stretch, he has held an 18:3 K:BB. Under the hood, Mountcastle has generated an above-average .264 xBA and a .456 xSLG, which suggest he should continue to see positive regression later this season. He has also generated an elite 50.9% hard-hit rate. This afternoon, Ryan O'Hearn will shift to first base and will bat in the two-hole.

Baltimore Orioles outfielder Tyler O'Neill (shoulder) remains out of the starting lineup on Saturday when they continue a series against the Washington Nationals. O'Neill was scratched from the lineup on Friday due to discomfort in his left shoulder. Fantasy managers should continue to monitor his status leading up to Sunday's game, in case the Orioles continue to hold him out of action. Over his last seven games, O'Neill has tallied just one hit and swiped two bags. This afternoon, Heston Kjerstad will cover right field, which opens left field for Ramon Laureano. Through 24 games this season, O'Neill has held a modest .188 AVG with a hefty 29% strikeout rate. The Orioles are worth targeting in DFS facing Washington right-hander Jake Irvin.

Miami Marlins catcher Agustin Ramirez and outfielder Derek Hill are not in the starting lineup on Saturday when they continue a series against the Tampa Bay Rays. Since being promoted to the major leagues, Ramirez has taken the starting job behind the dish. Over his last 10 games, Ramirez has been productive at the plate, holding a .297/.381/.596 slash line with five doubles and two home runs. In addition, outfielder Derek Hill will take a seat. Hill has started in each of the past four games since returning from the injured list. Over his last four, Hill has held a .214 AVG with two RBI. As a result, Nick Fortes will be behind the dish and Liam Hicks will serve as the DH. The Marlins are best to fade in DFS this afternoon, facing Tampa right-hander Drew Rasmussen.

Cincinnati Reds second baseman/outfielder Gavin Lux (back) was scratched on Saturday due to lower back spasms. Fantasy managers should continue to monitor his status leading up to Sunday's contest in case he needs additional time to recover. This afternoon, Will Benson moved over to left field. Over his last three games, Lux has been quite productive at the plate, posting three-straight multi-hit games. Over his last nine contests, Lux has posted a stellar .303/.361/.394 slash line with three doubles. Through his first 42 games in Cincinnati, Lux has been quite impressive, as he has held a .297/.386/.407 line with one home run and one stolen base. If Lux were to remain sidelined, this could open up more opportunities in the starting nine for Rece Hinds and Connor Joe.
