Los Angeles Dodgers relief pitcher Blake Treinen (lung) was used as the opener in Triple-A Oklahoma City's game on Thursday, throwing a perfect inning with two strikeouts. Treinen has looked good in his past two appearances, allowing just one hit and accumulating three strikeouts and zero walks. With five rehab appearances under his belt, he might be ready to make his 2024 season debut soon for the Dodgers after bruising his lung early in Spring Training. The veteran will be a welcome addition to the Dodgers bullpen and should see a decent share of work late in close games, making him a solid add in saves-plus-holds leagues.

St. Louis Cardinals outfielder Dylan Carlson (shoulder) went 2-for-3 with a home run in a rehab game with Triple-A Memphis. Carlson was playing in his second rehab game and was used as the designated hitter in this one after playing in center field on Wednesday. He will likely need a decent amount of time to get himself ready for a return to the majors, as he hasn't yet played in a game for the Cardinals this year after suffering a sprained left shoulder in Spring Training. The 25-year-old doesn't have much fantasy appeal, but he was once a well-regarded prospect and is still young, so a post-hype breakout is possible.

Houston Astros shortstop Jeremy Pena increased his hitting streak to five games as he tallied two hits in Thursday's victory over the Cleveland Guardians. Pena tallied his first hit of the game in the fourth inning with a ground ball to second base and then swiped second base but was unable to score. Later in the sixth, Pena ripped his first triple of the campaign to score Gabriel Arias. The shortstop would then score twice, courtesy of a Jon Singleton blast in the same frame and sacrifice fly in the seventh. Pena has a solid .333/.375/.467 line, and his underlying metrics suggest he could be in for a big summer with a .324 xBA. The former World Series MVP should be rostered in all formats and remains a solid DFS option.

Texas Rangers relief pitcher David Robertson tallied his 10th hold of the season and is now tied for the most in baseball with Nationals pitcher Hunter Harvey and Cardinals pitchers JoJo Romero and Andrew Kittredge. Robertson entered in the seventh inning with two outs to face Ildemaro Vargas with a runner on first and was able to retire him. Then, the 39-year-old remained in the game to pitch the eighth inning. He surrendered a leadoff walk to Jacob Young but then retired the next three batters via two strikeouts and a groundout. The veteran reliever carries a stellar 1.08 ERA and 0.84 WHIP across 16 2/3 innings with 20 punchouts. Robertson remains an elite option for holds and should be considered next in line to receive ninth-inning duties in Texas.

There has been speculation that Oakland Athletics rookie closer Mason Miller, who has the most pitches at 102-plus mph (19) this year, could be dangled at this summer's trade deadline. Rival executives are split on whether the A's would actually dare trade their biggest start with a move to Sacramento coming next year. Miller has topped out at 103.7 mph and is an "elite" closer that should bring "a prospect package worth pursuing." A rival executive envisions a bidding war that could make a Miller trade irresistible for the A's. "They may want to cash in while stock is so high." The 25-year-old former third-round pick in 2021 out of Gardner-Webb University has been lights-out in 2024 with a 1.26 ERA, 0.77 WHIP, eight saves and 29 K's in 14 1/3 innings, although a trade to a contender wouldn't necessarily mean he'd stay in a closer's role.
