Baltimore Orioles relief pitcher Andrew Kittredge (knee) was playing catch in the outfield on Saturday. The reliever is recovering from arthroscopic knee surgery he underwent earlier in the spring. Fantasy managers should continue to monitor his progression, but given that he has yet to throw on the mound, he is still several months away from returning. Last season, Kittredge enjoyed a productive campaign operating as a set-up man in St. Louis. Across 70 2/3 innings of work, the 35-year-old posted a 2.80 ERA with a 1.13 WHIP. He tallied 37 holds and held a 67:20 BB:K. He generated a modest 3.97 xERA and a .250 xBA, which suggests he could see some regression when he returns to the bump. When he returns to the mound, he will likely see high-leverage opportunities in Baltimore.

Boston Red Sox outfielder Jarren Duran is not in the starting nine on Saturday when the Red Sox continue a series against the White Sox. Duran has been in the starting nine in each of the first 15 games of the regular season. Instead, the Red Sox will give Rob Refsnyder the nod in left field and will have him bat cleanup. Through the start of the campaign, Duran has held a .231/.292/.308 slash line with three doubles and one home run. He has tallied eight RBI and swiped five bags. The 28-year-old has generated a strong 92.6 mph average exit velocity with a 73.8 mph bat speed, which suggests he should see positive regression when he returns to the lineup. He will likely return to the lineup on Sunday and face White Sox right-hander Shane Smith.

Baltimore Orioles infielder Jordan Westburg (upper body) is back in the starting lineup on Saturday afternoon. Westburg was held out of the starting nine on Wednesday due to an upper-body injury. He could have returned on Friday, but the competition against the Blue Jays was canceled due to rain. Westburg will cover the hot corner in this game and bat cleanup. Westburg has enjoyed a strong start to the campaign, posting a .256/.333/.465 slash line with three home runs and a 4:9 BB:K. He has tallied four RBI and scored seven runs. He has generated an elite .309 xBA with a .594 xSLG, which are both well above the average marks. He is a solid play in DFS this afternoon, facing right-hander Bowden Francis, who enters this game with a 3.18 ERA.

The Washington Nationals have placed shortstop CJ Abrams (hip) on the 10-day injured list. In a corresponding move, the Nationals promoted infielder Nasim Nunez from Triple-A. The infielder aggravated his right hip flexor during Friday's contest against the Miami Marlins. The 24-year-old was also kept out of the starting lineup earlier in the week due to a hip injury. Fantasy managers should continue to monitor his status in case he needs to miss additional time while on the injured list. Through his first 11 games of the campaign, Abrams has held a .244/.289/.585 slash line with two doubles, four home runs, and four stolen bases. While Abrams is out, fantasy managers should expect Paul DeJong to see most of the opportunities at shortstop.

The Chicago White Sox have placed outfielder Austin Slater (knee) on the 10-day injured list with a right knee meniscus tear. In a corresponding move, the White Sox promoted outfielder Greg Jones from Triple-A. Slater was unable to play on Friday due to this injury. However, given the severity of the injury, fantasy managers should expect Slater to miss at least the next few months. Through the early part of the campaign, the 32-year-old has posted a .250/.250/.500 slash line. Last season, Slater spent time with the San Francisco Giants, Cincinnati Reds, and Baltimore Orioles. Across 84 total games, Slater posted a .209/.321/.266 slash line. While Slater remains sidelined, Brooks Baldwin, Joshua Palacio, and Greg Jones will share time in right field.
