Tampa Bay Rays starting pitching prospect Mason Montgomery will look to improve in his fourth start of the season on Tuesday for Triple-A Durham. The left-hander has been off to a rocky start this season with a 10.80 ERA in three starts and has gotten worst in each outing. The lefty is the Rays top pitching prospect and has quickly risen through the system. Walks have been an issue for him in the past, but this year he has just three in 10 innings with 10 strikeouts. Despite being the clubs top pitching prospect, he is just inside their top 10 prospects overall. With his struggles and the Rays set with their rotation at the moment, Montgomery can remain on the waiver wire in all formats.

Washington Nationals starting pitcher prospect Mitchell Parker picked up the victory in his big-league debut versus the Los Angeles Dodgers on Monday evening. Parker, 24, got the daunting task of facing one of the toughest lineups in the league, but held his own. Over five innings, Parker allowed four hits, two runs, zero walks and struck out four. Strikeouts have been a big part of his game throughout his minor league career and he could be an asset to managers if that translates to the big leagues. Moving forward, Parker is in line to face another tough offense in the Houston Astros this weekend. Parker should be avoided in that matchup, but as the case with many prospects, they are always worth keeping an eye on as the season progresses.

Chicago White Sox pitching prospect Nick Nastrini performed well in his big-league debut versus the Kansas City Royals on Monday. Nastrini suffered the loss, but didn't look overmatched in his first outing. The right-hander went five innings and allowed three hits, two runs, two walks and five strikeouts. Nastrini should be expected to remain in the rotation with the White Sox season going nowhere and it being wise to develop young talent, but nothing is guaranteed. Moving forward, Nastrini now is nothing more than a streamer in favorable matchups, but he has the upside to help in deeper leagues, if he continues to improve. The right-hander is in line to face a tough Philadelphia Phillies lineup this weekend and should be avoided.

The Los Angeles Dodgers are calling up outfield prospect Andy Pages. Pages, 23, receives the promotion after hitting a ridiculous .371 with five home runs, 15 RBI and two stolen bases in 62 at-bats for Triple-A Oklahoma City. The Cuban product has recovered in a strong way from a torn labrum that shortened his 2023 campaign and will to carry his successes to the next level. Pages has always shown plenty of power in his bat and has good plate discipline. Playing time will be a factor in his ability to help fantasy managers, but veterans Chris Taylor and Enrique Hernandez haven't done much to earn everyday starts so far. Managers in dynasty leagues should already have Pages rostered and he is worth a speculative add in redraft leagues with managers keeping an eye on his playing time.

Chicago Cubs starting pitcher Ben Brown earned his first quality start of his career in a no-decision on Monday versus the Arizona Diamondbacks. Brown went six innings and allowed one hit, one run, two walks and struck out four on the evening. The rookie has been very impressive since filling in for the injured Justin Steele (hamstring). Steele is still a few weeks away from returning, but fellow starter Jameson Taillon (back) is returning this week and the question around the Cubs has been who will he be replacing. Brown has earned another turn in the rotation, but managers will want to wait and see how Taillon's return effects the rotation. If Brown were to remain in the rotation, he would face a weak Miami Marlins lineup this weekend and would be worthy of rostering in deeper leagues.
