St. Louis Cardinals pitcher Luke Weaver will get the nod to start Sunday against the Reds, pushing starting pitcher Jack Flaherty back to Monday. Weaver was recently demoted to the bullpen, so he's a risky streaming proposition for this game, even in a good matchup against Cincinnati. On the year, the 25-year-old is 7-11 with a 4.59 ERA, 1.42 WHIP and career-low 7.9 K/9 in 27 outings (24 starts).

St. Louis Cardinals starting pitcher Luke Weaver is being moved to the bullpen in favor of starter Daniel Poncedeleon, who will start on Tuesday against the Dodgers, according to manager Mike Shildt. Weaver has been too inconsistent, going 6-11 with a 4.67 ERA, 1.42 WHIP and 112 K's in 125 1/3 innings. You can drop him if you own him. Poncedeleon took a no-hitter into the seventh inning in his major league debut July 23 against the Reds in his only start so far. He's been great in relief, too, making him an intriguing pickup in deep mixed leagues. We wouldn't recommend him as a great streamer against the Dodgers this week, though.

Weaver will be removed from the Cardinals rotation, with Daniel Poncedeleon taking his place and starting Tuesday, Rob Rains of StLSportsPage.com reports.

Interim manager Mike Shildt confirmed Friday that there are no immediate plans to remove Weaver from the starting rotation, Jenifer Langosch of MLB.com reports.

St. Louis Cardinals starting pitcher Luke Weaver was unable to complete the fourth inning on Thursday. He ended up pitching just 3 2/3 innings, allowing four runs (two earned) on seven hits and a walk. He struck out just one and threw 71 pitches to get just 11 outs. It was a rough outing for Weaver, whose record dropped to 6-11. Meanwhile, his ERA went up to 4.67. He's had some good outings, but he's been far too inconsistent to be a reliable fantasy option in most leagues.

Weaver (6-11) tossed 3.2 innings Thursday, allowing four runs (two earned) on seven hits and a walk in the 5-4 loss to Washington. He took the loss and struck out just one batter.

St. Louis Cardinals starting pitcher Luke Weaver (finger) will move up to start Thursday against the Nationals. That will push starter Jack Flaherty to Friday against the Brewers. Weaver's overall numbers on the year don't look that great (4.66 ERA), but he has fanned 111 hitters in 121 2/3 innings and hasn't allowed more than three earned runs in a start since a blowup on June 30 against the Braves. He's a little bit more risky than usual after being scratched on Sunday.

Updating a previous report, interim manager Mike Shildt confirmed Tuesday that Weaver (finger) will make his next scheduled start Friday against the Brewers, Tom Timmermann of the St. Louis Post-Dispatch reports.

The Cardinals are hopeful that Weaver (finger) won't be forced to miss another start, Jenifer Langosch of MLB.com reports.

St. Louis Cardinals starting pitcher Luke Weaver pitched well on Monday but ended up taking a loss as the Cardinals offense could only score one run. Weaver pitched six innings, allowing two runs on seven hits. He struck out five and did not walk a batter. It was a good effort from Weaver and he earned a quality start, but the Marlins took a shutout into the ninth and escaped with a 2-1 win, giving Weaver the tough luck loss.

St. Louis Cardinals general manager John Mozeliak said the team doesn't have any current plans to remove starting pitcher Luke Weaver from the rotation despite his poor form over the last two months. Weaver has gone six innings just three times in 12 starts since May 28 and went just 2 2/3 innings on Wednesday. His ERA has risen to 4.75 and his WHIP currently stands at 1.41. Weaver has upside but should probably be avoided until he can get back on track.

Cardinals starting pitcher Luke Weaver has had himself a rough season so far. After a couple of smooth outings in July, Weaver found himself in hot water once again in Chicago. Weaver allowed 12 men on base and somehow only gave up three runs while only striking out two in four innings. The 24-year old has been a disappointing fantasy asset in 2018. Some geniuses such as myself drafted Weaver in the top 100 of drafts expecting a repeat of last season's performances. It's safe to say that we have been bamboozled. Although Weaver has shown glimpses in recent outings and sporadically throughout the season, it's becoming more and more evident that he won't be a reliable starter this year.

It was an excellent quality start for Weaver, who won his fifth game and lowered his ERA to 4.92.

St. Louis Cardinals starting pitcher Luke Weaver picked up his fourth win of the season on Sunday. He pitched 5 2/3 innings, allowing two runs on five hits and two walks while striking out nine. He missed a quality start by just one out, but his fantasy owners were certainly happy with the nine strikeouts. Weaver hasn't been great lately as he's seen his ERA bloat to 4.59, but Sunday's start was a step back in the right direction.

It was another uninspiring start by Weaver, who got off to an excellent start this season but has hit a bit of a bump in the road recently. He's been able to avoid having any truly awful starts, but it's been a while since he's had a particularly strong one either. He'll hope for better results his next time out.

He ended up pitching 5 1/3 innings, coughing up nine hits and a walk while striking out four. Weaver took the loss, dropping his record to 3-6. He looked like he was coming out of a slump a few starts ago, but has turned in two very pedestrian-at-best starts since then. He holds a 4.52 ERA on the season and will need to start pitching better to maintain his rotation spot all year.

He was through the first three innings with just one hit and one run allowed, but then the fifth inning happened, which featured two walks ahead of a Yoenis Cespedes blast over the fence. In total, Weaver threw just 50 of his 95 pitches for strikes. Weaver will return to the mound on Sunday against the Pittsburgh Pirates and will look for better results.

The St. Louis Cardinals will have Luke Weaver make the start on Tuesday in place of Adam Wainwright (elbow). Wainwright was placed on the disabled list with right elbow inflammation but isn't expected to miss more than a start or two. Some thought rookie Jack Flaherty would come up to make the start, but it seems like the Cardinals will use off days to keep their rotation the same, simply skipping Wainwright's start.

Coming into the game, Weaver had only given up four runs total in 17 1/3 innings of work, so Thursday was by far his worst start of the season so far. He should bounce back in his next outing and remains an exciting young fantasy starter.
