Pfaadt allowed one run on one hit and three walks over five frames in Sunday's win over the Giants. He struck out five and did not factor in the decision.

EDGE Analysis

Pfaadt turned in the best start of his MLB career Sunday. The only hit he allowed, a solo shot by Michael Conforto, accounted for the Giants' lone run. Pfaadt coughed up 13 runs in his first two career starts before Sunday's strong performance. His ERA still sits at an unsightly 8.59 with an 11:6 K:BB. Pfaadt's next start is projected to be in Pittsburgh.

Pfaadt (0-1) took the loss Tuesday versus the Marlins, allowing six runs on seven hits and two walks while striking out three over five innings.

EDGE Analysis

Pfaadt had trouble with Jorge Soler, who accounted for two home runs and five RBI against the Arizona rookie. That's after Pfaadt gave up four homers in his debut versus the Rangers last Wednesday. The top prospect came to the majors with plenty of hype, but a 12.10 ERA through 9.2 innings suggests he may not quite be ready for the show yet. Manager Torey Lovullo said after Tuesday's game that Pfaadt will get another turn in the rotation, Theo Mackie of The Arizona Republic reports. That outing is likely to come over the weekend at home versus the Giants, but it's safe to say Pfaadt could have a short leash if he doesn't get his homer problem under control.

Pfaadt is scheduled to start Tuesday's game against the Marlins at Chase Field.

EDGE Analysis

Even though Pfaadt was tagged for seven earned runs on nine hits -- including four home runs -- in his MLB debut last Wednesday at Texas, the Diamondbacks will give one of their top pitching prospects at least one more chance to prove he's worthy of a longer stay in the big-league rotation. Assuming Pfaadt can escape Tuesday's outing with a more credible line than he submitted in his debut, he'll likely receive his second start of the week this upcoming Sunday against the Giants, also at Chase Field. Pfaadt led all minor leaguers with 218 strikeouts in 2022 and never posted a walk rate above 6.5 percent across any of his stops as a professional, so if he can do a better job of limiting damage on flyballs in his future starts, the right-hander's fantasy upside could be immense.

The Diamondbacks selected Pfaadt's contract from Triple-A Reno ahead of his scheduled start Wednesday against the Rangers at Globe Life Field.

EDGE Analysis

The 24-year-old right-hander will be making his much-anticipated big-league debut in Texas, stepping into a back-end rotation spot for Arizona after the team recently released Madison Bumgarner and optioned Drey Jameson to Triple-A. Pfaadt attracted attention in the minors through his gaudy strikeout rates, as he punched out 218 batters in 167 innings between Reno and Double-A Amarillo in 2022 and has struck out 30 in 25.1 innings thus far in 2023. The strikeout potential Pfaadt brings to the table makes him an intriguing speculative pickup in nearly any league where he might be available on the waiver wire.

Pfaadt will indeed be called up to make his major-league debut Wednesday against the Rangers, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

The writing was on the wall when the Diamondbacks listed Wednesday's starter as "TBA" and now comes confirmation that Pfaadt will fill that spot. One of the top pitching prospects in all of baseball, the 24-year-old right-hander has registered a 3.91 ERA, 1.18 WHIP and 30:6 K:BB through 25.1 innings (five starts) this season with Triple-A Reno. He tallied 218 strikeouts in 167 innings last year between Double-A and Triple-A. That swing-and-miss upside makes Pfaadt a must-add in all standard fantasy formats.

Pfaadt could be promoted from Triple-A Reno to start Wednesday against the Rangers at Globe Life Field, Nick Piecoro of The Arizona Republic reports.

EDGE Analysis

Nothing has been officially announced by Arizona, but the fact the Diamondbacks aren't yet listing a confirmed starter for Wednesday points to Pfaadt likely getting the call to the big leagues. Pfaadt has thus far checked all the boxes for his Triple-A development, and he would be available to make the start Wednesday on six days' rest. Pfaadt, who logged 167 innings in the minors last season, has a career 3.00 ERA, 1.05 WHIP and 104 strikeouts in 87 innings in the hitter-friendly Pacific Coast League.

Arizona manager Torey Lovullo said Monday he has no plans to use a four-man rotation, meaning Pfaadt could be called up to take the demoted Drey Jameson's spot in the rotation, Theo Mackie of the Arizona Republic reports. "We have not made any decisions, but I don't think a four-man rotation right now is anything we're interested in," the manager said.

EDGE Analysis

The Diamondbacks demoted Jameson to Triple-A Reno on Monday, and with three days off over the next two weeks, the team could get by with a four-man rotation for a stretch. However, Lovullo doesn't seem inclined to go that way. Pfaadt, who started last Thursday for Reno, is scheduled to pitch for the affiliate again Wednesday. Unless that plan changes, any promotion for Pfaadt likely wouldn't come until next week.

Pfaadt allowed three hits and one walk while striking out eight over seven scoreless innings for Triple-A Reno on Thursday.

EDGE Analysis

Pfaadt turned in his most dominant performance of the season during a week the organization's parent club underwent a shakeup in the rotation. The Diamondbacks designated Madison Bumgarner for assignment; however, the club opted for Tommy Henry as an initial replacement for a start this coming Monday. Arizona general manager Mike Hazen said logistics were the main reason for that decision, meaning Henry's schedule created the least impact to the current rotation pattern, per Theo Mackie of the Arizona Republic. Hazen considered bringing Pfaadt up to start Friday, but the GM acknowledged the cascading effect it would have on the rotation's existing members. Hazen added that he feels Pfaadt is ready to pitch in the majors. The performance of the organization's top pitching prospect appears to back up the GM's claims. After a rocky first start this season, Pfaadt has settled in over three subsequent outings, posting a 1.62 ERA and 18:4 K:BB ratio over 16.2 innings.

Pfaadt is scheduled to start Thursday for Triple-A Reno, Sam Dykstra of MiLB.com reports.

EDGE Analysis

It's notable that Pfaadt is basically on the same pitching schedule as Madison Bumgarner, who was designated for assignment by the Diamondbacks on Thursday. Pfaadt could eventually slide into Arizona's starting rotation as a direct replacement for Bumgarner, though Tommy Henry will reportedly get the first chance to fill the opening. Pfaadt, 24, has posted a 3.63 ERA, 1.10 WHIP and 395:64 K:BB in 312 career minor-league innings and entered the 2023 campaign as a consensus top-100 prospect. He's tallied 17 strikeouts through 13.1 frames this season with Reno.

Pfaadt allowed two runs on six hits and a hit batsman while striking out five over five innings, claiming his first win of the season for Triple-A Reno.

EDGE Analysis

Pfaadt, by coincidence or not, pitched on the same day that Madison Bumgarner had another disappointing start for the Diamondbacks and hinted at an injury following the game, Nick Piecoro of the Arizona Republic reports. Bumgarner talked about dealing with "stuff" and a "lot going on," which set off speculation about a trip to the injured list, or Arizona pulling the plug on him as a starter. If either of those scenarios play out, Pfaadt looks like the obvious fill-in, given he's on the same five-day schedule as Bumgarner.
