But Severino, baseball's No. 19 overall prospect, set a career-high with seven innings pitched, holding Syracuse to one run on four hits and a walk while throwing 94 pitches.
Severino went 2-2 with a 3.32 ERA in eight starts for Double-A Trenton this season before the promotion. He lasted only 4 1/3 innings in his Triple-A debut.
Meanwhile, right-hander Tyler Beede, a first-round pick in last year's Draft, showed why the Giants bumped him up to Double-A this week.
Beede allowed only two hits over seven shutout innings in his debut for the Richmond Flying Squirrels, striking out four and walking three as he earned the win.
Beede, the Giants' No. 3 prospect, was 2-2 with a 2.24 ERA through nine starts for Class A Advanced San Jose.
More standout performances from Top 100 prospects on Friday
• Twins No. 1 prospect (No. 1 overall) Byron Buxton went 3-for-5 and scored a run as Double-A Chattanooga beat Tennessee, 6-5. Baseball's top prospect is now hitting .264/.326/.481 with six homers, 11 triples, 35 RBIs and 39 runs through 51 games this season.
• Dodgers No. 1 prospect (No. 5 overall) Corey Seager launched his ninth homer of the season Friday night, his fourth since getting called up to join Triple-A Oklahoma City. The shortstop is now hitting an even .300 at the Triple-A level.
• Rockies No. 1 prospect (No. 13 overall) Jon Gray spun his second straight strong start, limiting Iowa to two runs over 6 2/3 innings for Triple-A Albuquerque. The No. 3 overall pick in 2013, Gray struggled to begin the year at Triple-A. But he's now surrendered three earned runs or fewer in seven consecutive starts.
• Cubs No. 2 prospect (No. 42 overall) Kyle Schwarber went 1-for-3 at the plate with two runs scored for Double-A Tennessee. But Schwarber's work behind the plate Friday might be more notable, as he caught two runners stealing -- including Buxton.
• Rangers No. 3 prospect (No. 47 overall) Nomar Mazara went deep for Double-A Frisco as the RoughRiders beat Tulsa, 4-1. It was Mazara's fourth homer of the year and his second in four games. He hasn't hit for much power, but the 20-year-old is hitting .291 with a .372 on-base percentage this year.
• Mets No. 2 prospect (No. 57 overall) Steven Matz put together another solid outing for Triple-A Las Vegas but suffered his fourth loss of the year. Matz held Memphis to one run on seven hits and four walks while striking out five over six innings, but the 51s were blanked, 1-0, in the seven-inning game. Still, Matz owns a 1.94 ERA through 12 games in the hitter-friendly Pacific Coast League.
Other notable performances from around the Minor Leagues
• Giants No. 17 prospect Adam Duvall launched his 13th homer of the season to help lift Triple- A Sacramento to its fourth straight win.

• Mets No. 9 prospect Gavin Cecchini notched four hits -- tying his career-high -- and scored the winning run for Double-A Binghamton in an 8-7 win over Reading. Cecchini hit two doubles and scored three runs on the day. The 21-year-old shortstop improved his batting line to .341/.392/.500.
• Orioles No. 16 prospect Mychal Givens recorded six outs for Double-A Bowie to earn his 12th save. Givens didn't allow a hit or a walk and struck out four to lower his ERA to 1.07 in 20 games. Givens had six saves in 64 career appearances prior to this season.
• Rangers No. 16 prospect Andrew Faulkner improved to 4-3 by tossing seven scoreless innings for Double-A Frisco. Faulker was faced with a tall task as he squared off against Jose De Leon, the Dodgers' No. 4 prospect. He outdueled De Leon, who allowed three runs in seven innings. Faulker struck out seven and issued just one walk.
• Rays No. 5 prospect Casey Gillaspie, the team's first-round Draft pick a year ago, went deep for the second time in as many games in Class A Bowling Green's 5-3 loss to Kane County on Friday.
