Long, meanwhile, fired six scoreless frames, scattering three hits while walking one and striking out eight to match his season high. It was his first BayBears victory since May 26, snapping a streak of seven starts without a win.
That's not to say the Angels' No. 5 prospect hasn't been good of late, however. After Tuesday's strong performance, Long owns a 1.46 ERA with 25 strikeouts in 24 2/3 innings over his last five starts -- a stretch that has helped the 23-year-old right-hander lower his Double-A ERA to 2.97 through 78 2/3 frames (15 starts).
Providing the offensive support for Long was Angels No. 2 prospect Matt Thaiss, who went 1-for-4 with an RBI double in his Double-A debut. A first-round Draft pick in 2016, Thaiss was promoted to Mobile after hitting .265/.353/.399 with eight homers in 84 games with Class A Advanced Inland Empire.
The rest of the best performances from top prospects Tuesday
• Coming off of his impressive showing in the SiriusXM All-Star Futures Game, No. 86 overall prospect Ronald Acuna (Braves' No. 7) connected on his 12th home run in a 1-for-4 performance for Double-A Mississippi. The homer was the 19-year-old center fielder's ninth in 56 games with the M-Braves, during which he's hitting .318 with 18 steals.
• D-backs No. 4 prospect Dawel Lugo plated three runs and went 2-for-4 to pace Double-A Jackson's offense in a win over Mississippi. The 22-year-old third baseman has opened the season's fourth month on a tear, posting a .389 average with four doubles and eight RBIs in 11 games.
• Indians No. 5 prospect Nolan Jones doubled in his first at-bat and added an RBI single in his second trip to the plate en route to his third multihit game for Class A Short Season Mahoning Valley. The double was the fourth of the season for the 2016 second-rounder, who owns a .741 OPS through his first 19 games in the New York-Penn League.
• In his first game back since representing the U.S. in the SiriusXM All-Star Futures Game, Marlins No. 3 prospect Brian Anderson went 1-for-2 with two RBIs and two walks as Double-A Jacksonville edged Biloxi, 4-3. The 24-year-old third baseman is having a strong campaign in the Southern League, where he's hitting .256 with a career-high 14 homers and a vastly improved strikeout rate through 84 games.
• Marlins No. 13 prospect Albert Guaimaro extended his hitting streak to eight games in the Rookie Gulf Coast League with his second multihit performance of the season. The 18-year-old went 2-for-6 with a triple, two runs scored and a stolen base.
• Twins No. 4 prospect Fernando Romero lowered his ERA to 2.78 behind five scoreless innings for Double-A Chattanooga. He allowed two hits, walked one and struck out five, with 43 of his 63 pitches going for strikes in the outing. The 22-year-old righty has 91 strikeouts and just three home runs allowed in 90 2/3 innings (16 starts) this season.
• Pitching in relief of Adams for Birmingham, White Sox No. 26 prospect Aaron Bummer fired 1 2/3 scoreless frames, allowing one hit and one walk while recording three of his five outs via the strikeout. He owns a 3.00 ERA with 34 strikeouts in 33 innings (17 games) since moving up to the Southern League.
