The 23-year-old righty, acquired from Toronto in the Troy Tulowitzki blockbuster last July, has pitched brilliantly in his first taste of the Triple-A level, going 2-0 in five starts with a 1.52 ERA, 1.04 WHIP and 25/9 K/BB ratio in 29 2/3 innings.
Shipley, meanwhile, managed to keep the opposing team off the board for a second straight start, tossing six scoreless innings of four-hit ball with five strikeouts and two walks. Since giving up six earned runs in his outing on April 21, the D-backs' No. 1 prospect has rattled off 13 consecutive scoreless frames across his past two starts, with just seven hits allowed and 13 strikeouts in that span. On the season, the 24-year-old is 2-1 with a 3.26 ERA and 20/6 K/BB ratio in 30 1/3 innings (five starts).
Though both Hoffman and Shipley were at their best, neither right-hander was able to pick up a win in Sunday's game, which ultimately was won by Reno on Peter O'Brien's (D-backs' No. 10) walk-off home run in the bottom of the 12th inning. The long ball was O'Brien's eighth of the season and moved him into a tie for the Minor League lead.
The rest of the best performances from top prospects Sunday
• No. 8 overall prospect Tyler Glasnow (Pirates' No. 1) issued a season-high five walks over five innings but was still plenty dominant as he allowed two hits in his second straight scoreless start for Triple-A Indianapolis. The hard-throwing right-hander struck out seven in the win and now has 37 strikeouts in 26 innings (12.8 K/9) this season, while opposing hitters are batting .187 with just 17 hits against him in that span.
• No. 34 overall prospect Raul A. Mondesi (Royals' No. 1) and Bubba Starling (Royals' No. 7) provided the offense in Double-A Northwest Arkansas' win against Tulsa as they combined to go 6-for-8 with three extra-base hits and four runs scored. Mondesi hit a double, scored twice, plated a pair and swiped his 10th bag of the season as part of a 3-for-4 effort, while Starling, who also finished 3-for-4 with a double, connected on his fourth home run of the season. On the mound, lefty Matt Strahm (No. 10) recorded a season-high eight strikeouts and allowed one earned run in five innings for the Naturals.
• No. 63 overall prospect Cody Reed (Reds' No. 3) took a no-hitter into the sixth inning en route to throwing seven innings of one-hit ball as Triple-A Louisville shut out Norfolk, 3-0. The 23-year-old southpaw, whom the Reds acquired from Kansas City in the Johnny Cueto deal last July, has been sharp so far this season -- his first at the Triple-A level -- for the Bats, posting a 1.62 ERA, 0.90 WHIP and 17/5 K/BB ratio in 16 2/3 innings (three starts).
• No. 70 overall prospect Luis Ortiz (Rangers' No. 5) tossed a season-high six scoreless innings for Class A Advanced High Desert in a win against Rancho Cucamonga. The 20-year-old right-hander scattered four hits and fanned six in his fourth start (fifth appearance) of the year for the Mavericks, giving him 22 strikeouts and a 3.15 ERA in 20 innings on the season.
• Phillies No. 20 prospect Rhys Hoskins hit a solo home run, his fifth, to extend his hitting streak to 18 games, though it didn't keep Double-A Reading from falling to Portland in 10 innings, 8-7. After a breakout 2015 campaign, Hoskins, a 2014 fifth-rounder, has continued to make strides this season at Reading, batting .256/.330/.488 with 17 RBIs in 21 games.
• In his third scoreless start of 2016, Angels No. 14 prospect Jaime Barria yielded one hit in five scoreless innings, striking out five, to lead Class A Burlington past Fort Wayne. After giving up four earned runs in three innings during a shaky season debut, the 19-year-old righty has surrendered just two earned runs in 20 innings over his last four starts.
• Giants No. 18 prospect Jarrett Parker had a monster day at the plate for Triple-A Sacramento, going 3-for-4 with three home runs, six RBIs and four runs scored in a win against Salt Lake. The three-homer performance was the second of his professional career, as he also accomplished the feat in the big leagues with the Giants last September. While Parker had a game to remember Sunday, the 27-year-old outfielder is batting just .203 in 20 games this season.
• Scouts questioned whether Mariners No. 4 prospect Tyler O'Neill's aggressive approach and power frequency would translate in Double-A as it did in previous years. The 20-year-old slugger hasn't had any problems so far, though, as he connected on his sixth home run on Sunday to power Jackson past Mobile, 6-4. More significant is that O'Neill is also batting .313/.383/.578 and showing better plate discipline, with an encouraging 10/29 BB/K ratio and career-best 10.6 percent walk rate in 22 games for the Generals.
