Houston Astros prospect Cam Smith will start on the bench for a second straight game for Monday's series opener against the hosting Seattle Mariners at T-Mobile Park. Mauricio Dubon will make the start in right field and will hit ninth against Mariners ace Logan Gilbert. Smith was amazing during spring training, slashing .342/.419/.711 with a 1.129 OPS, four home runs and 11 RBI in 15 Grapefruit League games, but it hasn't carried over to his first six MLB games in his rookie season. So far in 21 plate appearances, the 22-year-old has gone just 2-for-18 with two walks and nine strikeouts for a .111 batting average. Last year's No. 14 overall pick will hopefully benefit from a couple of days off, but fantasy managers may not want to reinsert him into their starting lineups this week until he shows signs of breaking out of his slump. Dubon has three hits in 10 career at-bats against Gilbert but will be a weak DFS play.

Toronto Blue Jays starting pitcher Easton Lucas will get the starting nod against the Boston Red Sox on Tuesday. The right-hander received an extra day of rest with Jose Berrios moving up to start on Monday. Lucas looked good during his season debut against the Washington Nationals. He tossed five scoreless innings, allowing one hit, and striking out three batters. The 28-year-old will get a tougher challenge this time around against a tough Red Sox lineup at Fenway Park. Lucas could offer some deep league or AL-only appeal, but fantasy managers shouldn't expect another scoreless outing from Lucas.

Cincinnati Reds outfielder Jake Fraley (side) has been scratched from the starting lineup ahead of Monday's game against the San Francisco Giants. He was slated to start in right field and bat eighth, but has been pulled from the lineup due left side pain. Fraley should be considered as day-to-day, but fantasy managers shouldn't be shocked if he ends up on the injured list. In his absence, Blake Dunn will shift to right field, while Jacob Hurtubise moves into the lineup and covers left field against right hander Logan Webb. Neither player is a viable streaming option against an elite pitcher such as Webb.

Houston Astros starting pitcher Spencer Arrighetti (thumb) was struck in the pitching hand by a line drive while playing catch during batting practice on Monday. It was a freak accident that resulted in Arrighetti breaking his right hand. Ouch, Arrighetti is looking at an extended absence as he could require surgery to fix the issue. His next scheduled start was Friday versus the Los Angeles Angels. The Astros haven't announced who will make that start yet. Right now, Colton Gordon and A.J. Blubaugh are two popular names in Triple-A Sugar Land. The expectation is that Arrighetti will miss at least a month of action, but it could be longer if he needs surgery.

Boston Red Sox catcher Connor Wong (hand) has been removed early during Monday's game against the Toronto Blue Jays. Wong was hit in the hand on a catcher's interference play during the first inning. He suffered a right hand contusion when George Springer hit him in the glove hand, which led to him being replaced. Carlos Narvaez took over behind the plate in the second inning as the Red Sox didn't want to take any risks. The expectation is that Wong will undergo further testing to determine the severity of the injury. For now, fantasy managers should consider Wong as day-to-day until there's another update.
