Quinn Mathews Fantasy Stats

The St. Louis Post-Dispatch's Derrick Goold reports that St. Louis Cardinals left-handed pitching prospect Quinn Mathews will be called up from Triple-A Memphis to start Game 1 of the team's doubleheader on Monday against the division-rival Cincinnati Reds. Right-hander Andre Pallante will get the nod for Game 2 for the Cards. Mathews, the team's No. 8 prospect per MLB Pipeline, was called up on Aug. 1 to make his major-league debut and allowed two earned runs with three walks and three strikeouts in five innings in a loss to the Toronto Blue Jays on the road. The 25-year-old southpaw and former fourth-rounder from Stanford University has gone 5-4 this year with a 3.27 ERA, 1.23 WHIP, and 120:61 K:BB in 99 innings and 21 starts for Memphis. Mathews will face a Reds squad that ranks 24th in the league in team OPS, but the young lefty could be sent right back down to Memphis following his second major-league start. In the long-term at the MLB level, Mathews projects as more of a back-end starter in St. Louis than an ace.

St. Louis Cardinals pitching prospect Quinn Mathews got one start for St. Louis this season before being called back down to Triple-A Memphis. In two starts back with Memphis, Mathews has allowed four earned runs in seven innings pitched with nine combined strikeouts in the two starts. In his lone big-league start, Mathews took a hard-luck loss to the Toronto Blue Jays with two earned runs in five innings pitched. Mathews has looked sharp all year long in the minors for Memphis and the left-hander is the No. 8 prospect for St. Louis with a 60-grade slider and changeup in his four-pitch mix. The Cardinals rotation is very young so Mathews will look for another shot at the MLB level. He is worth holding onto in redraft leagues because he does have good strikeout potential with a strong four-pitch arsenal.

St. Louis Cardinals starting pitching prospect Quinn Mathews is a priority target on the waiver wire ahead of his MLB debut on Saturday. Mathews is currently viewed as the team's No. 6 prospect on MLB.com and is outside the current top-100 rankings on MLB Pipeline. However, the southpaw has enjoyed a dominant stretch at Triple-A, which prompted the promotion. Over his last 56 1/3 innings at the top club (since May 28), the southpaw has been near-perfect, posting a 1.60 ERA, 0.83 WHIP, with a 67:22 K:BB. Before this noted stretch, Mathews struggled against the top hitters of the minor leagues, carrying a hefty 5.55 ERA with a 1.63 WHIP across 35 2/3 innings of work. While it is still unknown if he will remain with the major-league club for the long-term, his recent Triple-A production makes him a worthy target in all standard leagues ahead of his debut.

St. Louis Cardinals left-handed pitching prospect Quinn Mathews will be called up from Triple-A Memphis to make his major-league debut and start on Saturday in Toronto against the Blue Jays, according to Derrick Goold of the St. Louis Post-Dispatch. The 25-year-old 6-foot-5, 188-pounder should immediately be in play as a waiver-wire pickup for fantasy managers in all league formats as the Cardinals' No. 7 overall prospect, per MLB Pipeline. The former fourth-round pick in 2023 from Stanford University is getting the call to the Show after going 5-3 with a 3.13 ERA, 1.14 WHIP, and 111:52 K:BB in 92 innings across 19 starts at Memphis this year. Mathews has been particularly effective since June, posting a sharp 1.55 ERA in his 52 1/3 innings. He features a fastball, sinker, slider, and a changeup, and he'll occasionally mix in a curveball for good measure. Mathews has plenty of strikeout upside with an 11.5 K/9 in his three minor-league seasons, but mechanical issues have hurt his command/control at times. He could have a strong MLB debut this weekend against a Blue Jays offense with the second-worst OPS (.684) in all of baseball in 2026.

St. Louis Cardinals pitching prospect Quinn Mathews is coming off a superb start at Triple-A Memphis in which he hurled seven shutout innings with three hits and an unearned run with 10 strikeouts against three walks. Mathews picked up a win for his efforts, moving his overall record this season to 5-3. The left-hander has spent the entire season at Memphis, compiling a 3.13 ERA and a 1.14 WHIP with 111 strikeouts in 92 innings pitched. In four July starts, Mathews has racked up a 1.04 ERA and 0.77 WHIP as he has raised the level of his game as the summer months have heated up. The No. 7 prospect on the Cardinals' list, Mathews boasts a 60-grade changeup and a 55-grade slider. After four years at Stanford, the 25-year-old is nearing big league ready and it would be wise to add him now before a potential late-season promotion.

St. Louis Cardinals pitching prospect Quinn Mathews turned in another stellar effort at Triple-A on Friday evening and is on the verge of reaching the major leagues. Facing Triple-A Durham, the southpaw struck out an impressive 10 hitters over seven innings of three-hit ball. He walked only three batters and allowed one unearned run. Since May 28, the Stanford product has been among the most dominant pitchers at the top level in the minors and is making a strong case to join the Cardinals. During these noted 56 1/3 innings, the left-hander has posted a sharp 1.60 ERA with a 0.83 WHIP while holding a 67:22 K:BB. While there may not be a clear opening for the left-hander, his recent surge makes him a top prospect to stash among pitchers, as his debut could occur in early August.

St. Louis Cardinals pitching prospect Quinn Mathews appears to be on the precipice of a major league debut after a strong season at Triple-A Memphis. The southpaw has been rolling as of late, allowing two earned runs or fewer in eight of his last nine starts, but for the most part, he's been pitching well all year. Take away his worst three starts of the year, the Cards' sixth-ranked prospect owns a 1.89 ERA and 0.98 WHIP in the other 15 starts. Not to mention 101 strikeouts in 85 total innings pitched are also very usable for fantasy. Opponents are batting .171 off of him on the year, so if he can translate some of that success to the majors, he could be a productive pitcher for fantasy over the final two months of the season. Look for the 25-year-old to debut in the coming weeks, and managers in deeper 12-team leagues should consider stashing him in an NA spot ahead of time.

St. Louis Cardinals pitching prospect Quinn Mathews continued to impress in his latest start at Triple-A over the weekend, allowing just one earned run on three hits and one walk while striking out four over six innings pitched. It was the eighth time in his last nine starts that the southpaw yielded two earned runs or fewer, pitching to a 1.82 ERA, 0.83 WHIP, and a 20.7 K-BB% over that stretch. For the season, the Cards' sixth-ranked prospect owns a 3.39 ERA, 1.16 WHIP, and a 15.0 percent K-BB% in 18 starts, but this recent nine-game stretch could give the team plenty of confidence in giving the 6-foot-5 hurler his long-awaited shot in the majors. The 25-year-old has plenty of strikeout potential, so if he can just limit the walks as he has in this recent run of success, then there is enough fantasy appeal here to make the Stanford product worth stashing in deeper 12-team leagues ahead of his eventual call-up.

St. Louis Cardinals left-handed pitching prospect Quinn Mathews is red-hot in July and is coming off an excellent pitching outing on Saturday for Triple-A Memphis. Mathews went six innings and allowed just one run on three hits with four strikeouts in a no-decision. With his start on Saturday, Mathews lowered his July ERA to 1.42 with a 0.74 WHIP in three starts during the month. Altogether in Memphis this year, Mathews is 4-3 overall with a 3.39 ERA and 1.16 WHIP and 101 strikeouts in 85 innings pitched. A fourth-round pick out of Stanford, Mathews has risen to the Cardinals' No. 6 overall prospect. The strikeout upside of Mathews makes him a tantalizing prospect on the waiver wire, and fantasy managers should act accordingly. His upside makes him worth an early shot, and he could pay off with a strong second half.

St. Louis Cardinals pitching prospect Quinn Mathews has been striking out batters at a high rate all season in Triple-A Memphis, making him a high-upside option on the waiver wire. Mathews has punched out 97 batters over 79 innings pitched at Memphis this season, compiling a 3.53 ERA and 1.20 WHIP as he continues to make a case to join the St. Louis rotation. The left-hander is the No. 6 overall prospect for the Cardinals, so he has the pedigree; he is just waiting for an opening at the major league level. But now might be the time to act for fantasy managers, as his high strikeout upside makes him a desirable pitcher on the free-agent market. In June, Mathews posted a 2.05 ERA over five starts, and so far in July, he has posted a 1.38 ERA over two starts. He has been picking things up lately at Triple-A and proving he could be ready for a shot with the Cardinals. At 25 years old, his time might be now for fantasy, and he has solidified himself as a top stash target among pitching prospects.
