Pfaadt allowed one run on three hits and struck out four over five innings in Tuesday's exhibition game against the Guardians.

EDGE Analysis

Pfaadt made his first start since March 10, although he's pitched on the back fields between then and now. He finished spring training with a 6.75 ERA and a 6:1 K:BB over 10.2 innings. He's expected to start the fourth game of the season, March 31, at home against the Rockies.

Pfaadt allowed four runs on four hits while striking out one over 2.2 innings in Sunday's start against the Dodgers.

EDGE Analysis

Pfaadt was removed after he retired just two of the first six batters and then re-inserted to pitch the second and third innings. He set down the side in order after coming back into the game. Despite the results, Pfaadt told Steve Gilbert of MLB.com that the outing was the best he felt in three spring starts. He's slotted in as the Diamondbacks' No. 4 starter.

EDGE Analysis

Pfaadt, who made his second Cactus League start, was pleased with the results, particularly in the sequencing of his changeup and slider, per Jack Magruder of MLB.com. "We figured some things out," Pfaadt said. "The slider is going to get better as we go. Something clicks every game, and that's a win. Fastball location, I can do better getting ahead." Both he and the Diamondbacks coaching staff are focusing on his pitch mix, which was credited for Pfaadt's success over the second half of 2023.

Pfaadt allowed two runs on two hits and one walk over one inning in Wednesday's spring start against the Guardians.

EDGE Analysis

Unlike previous starters making their Cactus League debuts, Pfaadt was only scheduled to throw one inning, per Steve Stockmar of MLB.com. The 25-year-old right-hander said his slider was off but it was good to get the work in. Pfaadt, who was a postseason darling last year, threw a career-high 178.2 total innings in 2023, which may be the reason to control his buildup during camp. Last spring Pfaadt was pitching to earn a roster spot, but this year he's locked into the rotation.

Pfaadt threw his first live batting practice session Tuesday, Jack Magruder of MLB.com reports.

EDGE Analysis

Pfaadt is looking to build off a strong finish to the 2023 season, including the postseason in which he recorded 5.2 scoreless innings in a Game 3 win over the Phillies in the National League Championship Series. The Diamondbacks point to that game -- Arizona was down 2-0 in the series -- as pivotal to their run to the World Series. Arizona pitching coach Brent Strom credited Pfaadt's better pitch mix for the right-hander's success over the second half and playoffs. Pfaadt expected to slot in at third or fourth in the rotation, depending on where manager Torey Lovullo wants to insert left-hander Eduardo Rodriguez, who signed a four-year deal with the D-backs during the offseason. Given that the top two members of the rotation -- Zac Gallen and Merrill Kelly -- are right-handers, the manager may want to break it up with Rodriguez third and Pfaadt fourth.

Pfaadt is projected to open the season at the Diamondbacks' fourth starter, Steve Gilbert of MLB.com reports.

EDGE Analysis

Pfaadt seemingly has the edge over other young starters -- Ryne Nelson, Tommy Henry -- as the fourth starter, given the way he pitched in the postseason. The 25-year-old right-hander turned the page on his regular-season 5.72 ERA to log a 3.27 postseason ERA. Pfaadt hinted at an improvement during the regular season when he had 4.22 ERA over the second half compared to 9.82 ERA prior to the All-Star break.

Pfaadt will start Game 3 of the World Series on Monday versus the Rangers, Theo Mackie of The Arizona Republic reports.

EDGE Analysis

After putting up a 5.72 ERA and 1.41 WHIP during the regular season, Pfaadt has seemingly flipped a switch during the playoffs, posting a 2.70 ERA and 1.08 WHIP with 22 strikeouts across 16.2 innings. The 25-year-old rookie will follow Zac Gallen and Merrill Kelly in the D-backs' rotation, with Pfaadt also in line to start Game 7 of the World Series, if necessary.

Pfaadt did not factor into the decision in Tuesday's 4-2 victory over the Phillies in Game 7 of the NLCS, allowing two runs on four hits and two walks across four innings. He struck out seven.

EDGE Analysis

Pfaadt once again chained together a successful outing, pitching only four innings in the contest as the team turned things over to the bullpen ahead of anticipated rest days. Despite the shorter appearance, Pfaadt still impressed in the strikeout column. He has now pitched to a 11.9 K/9 in 16.2 postseason innings, compared to a 8.8 mark across 96 regular season innings. The hope heading into the World Series is that Pfaadt can maintain his newly discovered strikeout gains and continue his postseason success. He has pitched to a 2.70 ERA and 1.08 WHIP with 22 strikeouts in those 16.2 playoff innings.

Pfaadt did not factor into the decision in Thursday's 2-1 victory over the Phillies in Game 3 of the NLCS, allowing two hits across 5.2 innings. He struck out nine.

EDGE Analysis

Pfaadt put together his best start of the postseason by far, but the team's offense could not get anything going, leaving him waiting on his first win of the playoffs. The rookie right-hander's success came on the back of his fastball and sweeper, which both were racking up whiffs to finish with 17 total swing-and-misses across 70 pitches. So far in the postseason, Pfaadt has pitched to a 2.21 ERA and 0.98 WHIP with 15 strikeouts across 12.2 innings

Pfaadt will start Game 3 of the NLCS on Thursday versus the Phillies, Bob Nightengale of USA Today reports.

EDGE Analysis

Zac Gallen took the loss in Game 1 on Monday in Philadelphia and Merrill Kelly will try to right the ship for the visiting Diamondbacks in Game 2 on Tuesday. Then it'll be Pfaadt in Game 3 on Thursday as the best-of-seven National League Championship Series moves to Arizona. The 25-year-old rookie right-hander did not face the Phillies during the regular season. He threw 4.1 scoreless innings on just 42 pitches in Game 3 of the NLDS against the Dodgers last Wednesday.
