Quantrill will begin the 2019 season at Triple-A El Paso, Jeff Sanders of The San Diego Union-Tribune reports.

EDGE Analysis

Quantrill and Logan Allen looked to be the two finalists for the Padres' last remaining spot in the rotation heading into Opening Day, but the team instead made the surprising decision to go with Nick Margevicius -- who had never pitched above the High-A level -- as their No. 5 starter. A 2016 first-round pick, Quantrill's numbers in the minors have never matched his draft pedigree, but the 23-year-old has performed passably enough to put himself on the short list for a promotion in the event the Padres require a spot starter at any point this season.

Quantrill is expected to make his final Cactus League appearance in Sunday's finale versus the Cubs and remains a candidate to crack the Padres' Opening Day rotation, Kevin Acee of The San Diego Union-Tribune reports.

EDGE Analysis

Joey Lucchesi, Eric Lauer and Matt Strahm already appear to have secured their places in the rotation, but Jacob Nix's elbow injury along with poor springs from Bryan Mitchell, Luis Perdomo and Robbie Erlin has paved the way for a trio of prospects to vie for the final two starting spots. Chris Paddack and Logan Allen are held in higher esteem as prospects and have largely outperformed Quantrill this spring, but the 23-year-old could boost his chances of breaking camp with the big club with a strong showing this weekend. The uncertainty that Quantrill will actually beat out Paddack or Allen for a job in addition to his meager production in the minors render the athletic right-hander little more than a late-round flier in NL-only formats.

Quantrill was promoted to Triple-A El Paso on Sunday, Jeff Sanders of The San Diego Union-Tribune reports.

EDGE Analysis

Quantrill posted a 5.15 ERA with 101 strikeouts over 117 innings with Double-A San Antonio, so his promotion wasn't performance related. The Padres lost a couple of starters via the waiver wire Sunday, so the youngster was forced up a level to fill vacated rotation spots. Despite his struggles, Quantrill could find himself in the majors down the stretch with the Friars falling out of contention.

Quantrill tossed seven shutout innings and struck out a season-high 10 batters in Double-A San Antonio's 6-0 win over Springfield on Sunday. He scattered three hits and a walk in the 97-pitch outing.

EDGE Analysis

The 23-year-old lowered his ERA to 4.15 through 12 starts with San Antonio and has given up just two runs in his last three outings, covering 17.2 innings over that span. With the right-hander beginning to turn the corner after a rough start to the Texas League campaign, it's not out of the question for him to receive the call to the big leagues at some point in the second half. Quantrill's above-average changeup and quality fastball give him a chance at developing into a serviceable back-end rotation member for the Padres.

The Padres extended an invitation to Quantrill for spring training.

EDGE Analysis

Quantrill split the 2017 season between the High A- and Double-A levels after earning a promotion to San Antonio in mid-July. Over eight starts with the club -- during his first opportunity in Double-A -- he posted a 4.04 ERA and 1.62 WHIP with a 34:16 K:BB in 42.1 innings. This marked his first full year as a professional after undergoing Tommy John surgery in 2015, which has hampered his projection as a front-end starter for the future. Spring training will be a good test to see how the 23-year-old fares against major-league hitting for the first time, and whether there's enough potential for him to possibly earn a late-season call-up during the 2018 campaign.

Quantrill, 22, has a 3.38 ERA and 20:8 K:BB in 29.1 innings since being promoted to Double-A San Antonio.

EDGE Analysis

The stats certainly aren't terrible for Quantrill, though his strikeouts are down and his walks are up since the promotion. Quantrill has made a successful return from Tommy John surgery, though it remains to be seen if his lanky frame will hold up to the rigors of being a starting pitcher, and he must continue the development of a third pitch. Nevertheless, he is one of the better pitching prospects for the Padres.

Quantrill will head to Double-A San Antonio on Tuesday, Sam Dykstra of MiLB.com reports.

EDGE Analysis

Quantrill had been pitching well for Lake Elsinore during his first year at the High-A level. In 14 starts, Quantrill accumulated a 3.67 ERA with a 1.39 WHIP. His 76:24 K:BB over the course of 73.2 innings is promising for the 21-year-old, especially while working his way back from Tommy John surgery in 2015. The right-hander is one of the top pitching prospects in the Padres system, and could make his way to Triple-A by 2018 if he continues on his current progression.

Quantrill, 22, has a 3.80 ERA and 50:17 K:BB in 47.1 innings for High-A Lake Elsinore.

EDGE Analysis

Quantrill has been impressive in the hitter-friendly confines of the California League, striking out more than a batter per inning while showing no ill effects from his 2015 Tommy John procedure. His innings will likely be limited this season, but the Padres have to be pleased with what they've seen so far.

Quantrill gave up one run on two hits and two walks while striking out seven over five innings in his debut start for High-A Lake Elsinore.

EDGE Analysis

The 22-year-old righty is probably a bit overqualified for High-A, but he entered the season with just 37 innings under his belt since undergoing Tommy John surgery in 2015 while at Stanford, so the Padres will keep the training wheels on to some extent at the beginning of the season. It is unclear what type of innings cap he faces this year, but it would not be surprising if he pitched his way to Double-A by the end of the season. He has No. 2 starter upside.
