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.
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.
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 San Antonio -- 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.
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.
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.
