Baltimore Orioles outfielder Cedric Mullins (quadriceps) is not in Saturday's lineup as the Orioles continue a series against the Houston Astros. Mullins was lifted from Friday evening's contest due to tightness and will be given a day off to rest. As a result, Colton Cowser will shift to center field, which opens up left and right field for Austin Slater and Anthony Santander, respectively. Prior to the injury, the 29-year-old center fielder was carrying an excellent .294/.478/.471 line across his past ten games. Fantasy managers should pay close attention to the Baltimore lineup before their game against the Astros on Sunday evening. The Baltimore outfield should be left out of your DFS lineup this afternoon as they will face Astros ace Framber Valdez, who is coming off a seven-inning scoreless performance.

Baltimore Orioles rookie infielder Jackson Holliday will take a seat on Saturday afternoon as the Orioles continue a four-game set against the Houston Astros. The top prospect has not tallied a hit in his past six games and will get a much-needed break to get himself back on track. Prior to the slump, the former first-overall selection was riding a stellar .283/.328/.585 line with five home runs and 14 RBI in his past 16 games. Fantasy managers should expect Holliday to rejoin the starting nine on Sunday evening. As a result, Ramon Urias will cover the keystone and bat in the nine-hole today. Urias is not worth considering in DFS competitions as he will face Astros left-handed pitcher Framber Valdez who is carrying a dominant 1.27 ERA and a 0.56 WHIP in his past three games.

Houston Astros outfielder Yordan Alvarez (neck) is being kept out of the lineup for the second straight day due to neck discomfort. As a result, Mauricio Dubon will cover left field and bat in the nine-hole this afternoon. Before the injury, Alvarez was carrying an incredible .364/.475/.652 line with five long balls, 12 RBI, and a 12:10 BB:K ratio since the start of the month. Fantasy managers should continue to pay close attention to the Houston starting nine prior to the series finale on Sunday evening. Dubon is riding a .233 AVG across his past nine games and should not be considered in DFS competitions this afternoon as he will face Baltimore right-hander Albert Suarez, who has tossed 17 2/3 straight scoreless frames with a strong 0.91 WHIP.

Miami Marlins outfielders Jesus Sanchez and Kyle Stowers are both out of Saturday's lineup as the Marlins continue a three-game set against the Chicago Cubs. Both Sanchez and Stowers will get the day off because the Cubs are sending out southpaw Shota Imanaga. As a result, Derek Hill will cover left field, David Hensley will cover right, and Cristian Pache will start in center. Hill has posted a solid .258 AVG in his past eight games while Hensley holds a .308 AVG in his past five. Fantasy managers should expect Sanchez and Stowers to return to the starting nine on Sunday afternoon as the Cubs are scheduled to send right-hander Javier Assad to the bump. Both Hill and Hensley should be faded in DFS this afternoon, as Imanaga allowed just one run in his last start.

San Francisco Giants relief pitcher Camilo Doval is set to return to the major leagues on Saturday, according to Andrew Baggarly of The Athletic. Doval was surprisingly optioned to Triple-A Sacramento earlier in August after posting a poor 8.59 ERA and a 1.91 WHIP in his previous seven 1/3 frames. At Triple-A, the right-hander held a solid 3.18 ERA and a 0.53 WHIP across five 2/3 frames of work. In Doval's absence, Ryan Walker settled in as the closer in the Bay Area by tossing seven frames of one-run ball (zero earned) with a 0.86 WHIP and a 2:16 BB:K ratio. Fantasy managers should pay close attention to who emerges as the top option for saves in San Francisco down the stretch.
