Pittsburgh Pirates infielder Jared Triolo (undisclosed) was a late scratch on Sunday due to an undisclosed injury. He was replaced by Isiah Kiner-Falefa in the starting nine. Fantasy managers should monitor Triolo's status leading up to their next contest against the St. Louis Cardinals on Monday evening. Triolo has had a slow start to the campaign, tallying just one hit over his first six contests. During this stretch, he has held a 1:5 BB:K and scored one run. Fantasy managers should continue to expect Isiah Kiner-Falefa to have a role in the starting nine while Triolo remains sidelined. Last season, Triolo posted a modest .216/.296/.315 slash line with nine home runs and eight stolen bases. When healthy, he should only be targeted in deeper formats given his low offensive upside.

Seattle Mariners infielder Jorge Polanco (knee) is dealing with soreness in his left knee and will be held out of the starting nine on Sunday afternoon. Fantasy managers should continue to monitor his status leading up to their next contest on Monday evening against the Houston Astros. Polanco underwent surgery on his knee last October but did not deal with too many issues during camp. However, the team will opt to exercise caution during the early part of the campaign. Instead, Dylan Moore will start at the hot corner, and Ryan Bliss will get the nod at the keystone. Through his first five games of the season, Polanco has enjoyed a strong start, posting a .450/.476/.750 slash line with two home runs and eight RBI. Polanco remains a solid depth infielder in deeper formats, given his strong start to the season.

St. Louis Cardinals catcher Ivan Herrera (knee) was removed from Sunday's contest against the Boston Red Sox. According to Katie Woo of The Athletic, the backstop needed assistance to leave the field. He was unable to put weight on his foot and was diagnosed with left-knee inflammation. Fantasy managers should continue to monitor his status but should not expect him to be in the starting lineup for the second half of the back-to-back on Sunday evening. Herrera has enjoyed an impressive start to the campaign, posting a .400/.455/1.100 slash line with two doubles and four round-trippers. He has brought in 11 runs and scored six times. If Herrera were to miss an extended period of time, fantasy managers should expect Pedro Pages to operate as the primary backstop in St. Louis.

Cleveland Guardians catcher Bo Naylor is not in the starting lineup on Sunday afternoon when the Guardians conclude a series against the Los Angeles Angels. Instead, veteran Austin Hedges will get the nod behind the dish and bat in the eight-hole. Naylor enjoyed a productive day at the plate on Saturday, going 2-for-3 with his first long ball of the campaign. Prior to this two-hit effort, Naylor went 2-for-20 through his first six games of the campaign with no extra-base hits. Fantasy managers should expect Naylor to return to the starting lineup on Tuesday afternoon when they begin a series against the Chicago White Sox. Hedges has started in just one game before Sunday and went deep in that contest. However, he should not be targeted in DFS while facing Los Angeles southpaw Tyler Anderson.

The Atlanta Braves have designated catcher Chadwick Tromp for assignment to open a roster spot for Sean Murphy (rib), who was activated off the 10-day injured list on Sunday. Tromp was able to make the Opening Day roster with Murphy beginning the season on the injured list. However, he was deployed as the clear No. 2 backstop behind Drake Baldwin. During his brief taste in the majors this season, he only saw five at-bats and did not tally a hit. If he clears waivers, he will then move to Triple-A Gwinnett. Across 61 career games in the majors, Tromp has posted a .224/.235/.385 slash line with 10 doubles and five home runs. Fantasy managers in deeper two-catcher formats should continue to hold Baldwin on their roster as he still could have fantasy value operating as the No. 2 option behind Murphy.
