    David Peterson allowed one run in five innings against the Orioles on Thursday despite walking four batters.

    Tyler O’Neill crushed a second-inning offering from Peterson for the lone run. Despite the walks, the Orioles only managed two at-bats with runners in scoring position. Peterson’s now alternated two decent starts with the Cubs against one mega-clunker that has his season ERA at 6.45. Even with the improvement, we’re not ready to recommend him in fantasy leagues.

    Peterson’s second start as a Cub did not go nearly as smoothly as his first. He allowed three runs apiece in each the second and third innings on his way to an ugly 10 spot. That rally in the second was the most frustrating because Peterson retired the first two batters he faced and had the Cardinals’ seven, eight, and nine hitters coming up. Suddenly, a double, single, and homer turned into three runs. Similarly, before being yanked in the fourth, he got two quick outs and then proceeded to walk three consecutive batters. Then he was pulled after a run-scoring single and reliever Bryse Wilson gave up a home run to let that last two inherited runners score. In the end, Peterson had poor command and was hit hard just like in many of his other starts this season.

    Peterson gave up five hits, walked none and struck out two. He improved to 4-6 with the win. Peterson’s Cubs tenure got off to a rocky start when Jackson Chourio homered on the first pitch he threw in Cubs blue. The 30-year-old left-hander was able to settle in and pitch into the sixth inning before handing it off to the bullpen with a 6-2 lead. Peterson has a 5.86 ERA, but his 4.04 xFIP points to a potential bounce back. He’s lined up to face the Cardinals at home next weekend.

    It’s a decent spot for Peterson to make his Cubs debut since Milwaukee ranks 22nd as a team in OPS against left-handed pitching this season. The 30-year-old southpaw was acquired from the Mets to shore up Chicago’s injury-ravaged rotation earlier this week. His immediate fantasy appeal is strictly limited to deeper mixed leagues given his struggles this year, but it’s possible a change of scenery helps him get back on track.

    Peterson joins a beleaguered Cubs’ rotation to provide some stabilization, but it’s worth noting that he’s been far from a reliable option for most of 2026 with a 6.09 ERA and 1.65 WHIP over his 68 innings with New York prior to the move. The left-hander has had success in the past prior to this year’s scuffles, and because of the litany of injuries to the Chicago staff, he’s going to be given some runway. He should make his debut for the Cubs in the coming days.

    Peterson provides Chicago’s injury-ravaged rotation with an immediate injection after struggling to a career-worst 6.09 ERA, 1.65 WHIP and 63/30 K/BB ratio across 68 innings for the Mets this season. The 30-year-old southpaw could certainly benefit from a change of scenery and should get an extended run with the Cubs who lost both Ben Brown (neck) and Edward Cabrera (hamstring) to the injured list earlier this week in addition to missing Cade Horton (elbow) and Jameson Taillon (hamstring) already. The Athletic’s Will Sammon adds that first base prospect Cole Mathis, who has posted a .981 OPS in the lower minors this season, is heading to the Mets in the deal.

    Scott is eligible to come off the injured list on Saturday, which would bump Kodai Senga back a couple days or out of New York’s rotation entirely. It’ll be David Peterson handling Friday’s series opener. The 27-year-old will wind up missing only a pair of starts after hitting the injured list with a hip impingement earlier this month. He had allowed three earned runs or fewer in eight consecutive starts prior to being tagged for four runs over 4 2/3 innings by the Cardinals during his last start before landing on the shelf. He boasts a strong 3.10 ERA, 1.35 WHIP and 47/19 K/BB ratio across 40 2/3 innings this season. He’s a decent streaming option for fantasy managers in deeper formats where he may have been dropped.

    Peterson walked back-to-back batters to start the game, which set the tone for the evening. The southpaw ran a ton of deep counts and it ultimately cost him. His biggest downfall was a three-run homer off the bat of Kyle Schwarber in the second inning. Peterson struck out five and walked four in the loss and now holds a 6.09 ERA on the year. He didn’t exactly make the case to get more starts in the near future, but the Mets aren’t exactly overflowing with options at the moment.
  • NYM Relief Pitcher #23
    He’s getting the nod over Tobias Myers, who gave up seven runs in 1 1/3 innings against the Reds on Monday. Peterson last started on May 26, when he surrendered six runs in five innings against the Reds. He has a 5.91 ERA in seven starts and eight relief appearances this season.

    Good grief. Starter, reliever, bulk pitcher, it doesn’t matter which role the Mets deploy Peterson in, he simply does not have it. He entered the game in the second inning and evaded trouble despite allowing two quick hits. Then, Nelson Velázquez and Jordan Walker each homered over the next two frames to put five runs off the board and another Cardinals’ rally in the fifth sent Peterson to the showers. Right now, Peterson has poor stuff and worse command. He and his 5.75 ERA should not be considered in any leagues.
  • NYM Starting Pitcher #23
    Sean Manaea will be given the opportunity to work as a bulk reliever, likely behind an opener, in Peterson’s spot in the rotation beginning on Monday. The last straw for Peterson appears to have been giving up six runs on 11 hits over five innings against the Reds on Tuesday. He holds a miserable 5.57 ERA and 1.67 WHIP across 53 1/3 innings on the season.

    Grayson Rodriguez (back) will return from the injured list to start against the Twins on Friday.

    That was the expectation all along, but the Angels finally confirmed it on Thursday. Rodriguez looked strong in his latest minor league rehab start, hurling 5 1/3 innings of one-run baseball at Triple-A Salt Lake. Fantasy managers may want to see how he looks one turn through the rotation before throwing him right back to the wolves.

    Justin Foscue went 2-for-3 with a homer, two RBI and a walk Thursday as the Rangers held off the Angels 7-6.

    Texas coughed up a 6-1 lead in the seventh but won the game on Wyatt Langford’s single in the bottom of the ninth. Foscue homered off Reid Detmers in the fourth and doubled in a run in the sixth. Both hits were off lefties, as is typical. He’s now hitting .367/.466/.796 in 49 at-bats against southpaws, compared to .216/.255/.353 in 51 at-bats versus righties. As a result, he’ll likely be on the bench Friday against Houston’s Hunter Brown.

    Nathan Eovaldi surrendered four runs — three earned — in six-plus innings and struck out 10 in a no-decision Thursday.

    Eovaldi had a 6-1 lead after six, but the seventh started with a catcher interference, a walk and a single, at which point Eovaldi exited. Peyton Grey came in and allowed all three runners to score while getting two outs. Tyler Alexander entered then and allowed both of Grey’s runners to score, making it a 6-6 game. Eovaldi still ends the first half on a four-game winning streak. He’s 9-7 with a 4.04 ERA overall. The 10 strikeouts were a season high. He fanned nine in each of his three previous starts.

    Reid Detmers gave up five runs and three homers in four innings Thursday against the Rangers.

    Detmers served up homers to Brandon Nimmo in the first, Ezequiel Duran in the third and Justin Foscue in the fourth. All were hit at 104 mph, oddly enough. We’ll feel better about Detmers as a fantasy starter if and when he gets out of Anaheim. He closes out the first half with a 3-6 record and a 4.19 ERA despite an excellent 123/35 K/BB in 108 2/3 innings.

    Kirby Yates dropped to 0-4 after giving up a run in the ninth Thursday against the Rangers.

    Yates came into a tie game in the ninth and gave up a groundball single, a sac bunt and then a long single off the wall in left to end the game. It was a tough break for a reliever who has been very good of late with little to show for it. It was the first run he’d allowed since June 22 and the first earned run since June 8. He’s still a candidate for saves in the Angels’ pen, though he has earned just two so far.

    Nolan Schanuel went 4-for-4 with two doubles, two RBI and a walk Thursday versus the Rangers.

    He had only one hard-hit ball, but Schanuel sent everything to the right spots tonight. It’s his second four-hit game as a major leaguer, with the other coming last July against the Mets. He’s hitting an adequate .269/.339/.393 on the season, but he still isn’t showing much in the way of upside.

    Jake Bauers clobbered a three-run homer on Thursday night, powering the Brewers to an 8-4 victory over the Cardinals.

    Bauers broke the game wide open with his 391-foot (110.3-mph EV) three-run shot off of Andre Pallante in the third inning, increasing the Brewers’ edge to 6-0. His blast would prove to be the difference in the ballgame. Bauers also singled, walked and struck out twice in the ballgame, finishing the evening 2-for-4. On the season, he’s now slashing .268/.368/.505 with 17 long balls, 57 RBI and five stolen bases.

    Brice Turang went 2-for-5 with a homer and two RBI on Thursday night as the Brewers dispatched of the Cardinals.

    Turang came through with an RBI single in the third inning that increased the Brewers’ lead to 3-0. He then rode home on Jake Bauers’ three-run shot. The 26-year-old second baseman then went deep himself in the seventh inning with a 419-foot (103.4-mph EV) solo shot off of Luis Gastelum in the seventh that increased the Brewers’ lead to 7-4. Turang is enjoying a great first half, slashing .269/.361/.464 with 13 homers, 56 RBI and 15 stolen bases in 401 plate appearances.

    Logan Henderson defeated the Cardinals in his return from the injured list on Thursday, surrendering three runs on just three hits over his 5 1/3 innings of work.

    Henderson struck out four batters on the evening while allowing only one base on balls. He allowed a run in the fourth inning on an RBI single off the bat of Lars Nootbaar. Henderson then ran into trouble in the sixth, exiting with two men on and one out — and both inherited runners immediately scored on a three-run blast by Jordan Walker. Henderson generated eight whiffs on 76 pitches on the night, posting a CSW of 28 percent. The 24-year-old hurler finishes the first half with a 3-1 record, 3.18 ERA, 0.99 WHIP and a 34/7 K/BB ratio across 28 1/3 innings through his first six starts. As long as he stays healthy, he should have plenty of mixed league viability over the second half of the season.

    Jordan Walker went 1-for-4 and swatted a three-run homer on Thursday night, but it wasn’t enough to power the Cardinals past the visiting Brewers.

    Walker turned a five-run deficit into a two-run deficit with his 406-foot (106.5-mph EV) three-run blast off of Chad Patrick in the sixth inning. That would be as close as they would get though. It was also Walker’s only hit in four at-bats in the contest. The All-Star slugger is enjoying an unbelievable first half, slashing .294/.354/.539 with 22 homers, 73 RBI and 12 stolen bases.
