Washington Nationals right-hander Mason Thompson (elbow) is set to be re-examined by team doctors this week after being shut down the last two weeks of camp with a sore elbow. Thompson had Tommy John surgery nine years ago as a junior in high school. He's avoided major injuries since then, but he did miss three months due to a right-biceps strain in 2022. Manager Dave Martinez admitted he's "a little concerned." Thompson was dominant at times out of Washington's bullpen, but he wasn't guaranteed a spot on this year's Opening Day roster, so his elbow injury is going to make it even tougher for him to earn a spot. He struggled through most of the second half in 2023 and finished with a 5.50 ERA and 1.56 WHIP in 51 games.

Washington Nationals third baseman/outfielder Nick Senzel (illness) was not in the team's Grapefruit League lineup on Monday against the New York Mets because he was feeling under the weather. With Senzel sitting out, prospect Brady House got the start at third base for the Nats. The 28-year-old Senzel is expected to see regular playing time at the hot corner in D.C. for the rebuilding Nationals in 2024. Perhaps the former first-round pick can pick things up with a change of scenery, but fantasy managers in most leagues should be content to wait and see what happens. Injuries have been the story of his career to this point. Senzel missed time in 2023 with the Reds due to toe and knee injuries and finished with a .236 average, a career-high 13 home runs, 42 RBI and six steals in 104 games.

St. Louis Cardinals designated hitter Matt Carpenter (wrist) was scratched from the team's Grapefruit League lineup on Monday due to a bruised left wrist after being hit by a pitch in a previous game over the weekend. Carpenter's injury doesn't sound very serious, but the Cardinals will take it easy on the 38-year-old left-hander for a day or two. Carpenter essentially became a bench coach for the San Diego Padres last year after hitting just .176/.322/.319 with five home runs, 31 RBI and 67 strikeouts in 237 plate appearances over 76 games played. It was a big disappointment after he hit 15 home runs in 2022 with the Yankees before getting hurt. It's unlikely at this point that Carpenter will have a resurgence as he returns to St. Louis.

Oakland Athletics right-hander Ross Stripling (finger) was originally scheduled to make his Cactus League debut with his new team on Monday against the Arizona Diamondbacks, but he is being pushed back a few days with what manager Mark Kotsay described as a minor cut on his right index finger. Instead, Mitch Spence, a Rule 5 draft pick, replaced Stripling on the mound. The injury to Stripling's finger doesn't sound serious at all. The 34-year-old is locked into Oakland's starting rotation in 2024 after being acquired in a trade with the San Francisco Giants. He'll be moving to another pitcher-friendly environment, but that's about where the positives end. Stripling doesn't miss many bats and won't get much run support from the A's offense. He's outside of RotoBaller's top-100 fantasy starting pitchers.

San Francisco Giants outfielder Jung Hoo Lee (side) is scheduled to play center field and bat leadoff on Tuesday in the team's Cactus League contest against the Seattle Mariners. Lee was scratched from making his spring training debut over the weekend due to minor side soreness, but he'll be ready to return on Tuesday. The 25-year-old Korean outfielder will be San Fran's starting center fielder in his first year in the States after the Giants signed him to a six-year, $113 million deal in free agency. Lee doesn't have much power in his bat, but he has excellent contact and on-base abilities and should provide value as a depth outfielder in mixed fantasy leagues in 2024 for his OBP, average and runs scored. However, there is also some concern that he might need a period of adjustment to increased MLB velocities.
