Johnson among 10 top prospect performers Wednesday

Red Sox No. 6 prospect allows 1 hit, strikes out 7 in 6 2/3 innings for Triple-A Pawtucket

With the Red Sox potentially looking for a starter to fill Joe Kelly's spot in the rotation, No. 6 prospect (No. 91 overall) Brian Johnson made his Wednesday start while Boston general manager Ben Cherington looked on.

The Triple-A Pawtucket hurler came through with a terrific performance, giving up one hit and one unearned run while striking out seven in a 6 2/3-inning no-decision. But his night had an awkward ending as he collided with a Rochester Red Wings runner while trying to cover first base.

Johnson got up after the collision, but was pulled from the game. The 24-year-old spoke with reporters afterwards and dispelled any talk of a stint on the disabled list, saying that he's already preparing for his start on Monday.

Those plans could be dashed if the Red Sox call Johnson up to the big league club.

"As of right now, I haven't heard anything," Johnson told the Providence Journal. "All I'm really worried about right now is my Day 2 side. I don't really know anything beyond that."

The rest of the 10 best performances from top Minor Leaguers

Brewers No. 21 prospect Yadiel Rivera played the hero for Triple-A Colorado Springs. Down 6-4 with two outs in the top of the ninth inning, Rivera smacked a three-run home run to give the SkySox a 7-6 lead, which the team held to win by that score. The clutch blast was his first homer since getting promoted on May 15. He's hitting .287/.316/.388 with 16 RBIs in since the promotion.

Cardinals No. 1 prospect (No. 76 overall) Stephen Piscotty went 3-for-5 while knocking out his second homer in three games. The Triple-A Memphis outfielder has double-digit home runs for the Redbirds, along with 20 doubles and 33 RBIs. He's also notched four multi-hit games since June 17.

Dodgers No. 1 prospect (No. 5 overall) Corey Seager ripped two homers in Triple-A Oklahoma City's loss to Colorado Springs, including a line-drive shot to right-center on the first pitch he saw. In the fifth, he launched another dinger -- this one a two-run blast -- to right-center. It was Seager's third multi-homer game this season, however, it ended on a sour note as the Oklahoma City shortstop committed a throwing error with two outs in the top of the ninth inning that allowed the game to continue and Yadiel Rivera promptly smacked a three-run home run to give Colorado Springs a 7-6 lead.

Indians No. 13 prospect Jesus Aguilar helped Triple-A Columbus break out of an offensive slump with a three-run homer. Orioles prospect Tyler Wilson shut the Clippers down for seven innings, but Aguilar jumped on his opportunity after Wilson exited. Aguilar's eighth inning blast was part of a 3-for-6 day. Columbus was able to tie the game in the eighth, 4-4, before Norfolk punched in a run in the 12th inning to win it, 5-4.

Marlins No. 7 prospect Adam Conley posted his best performance of the year for Triple-A New Orleans, giving up one hit while striking out two in six innings of shutout ball. The win improved his record to 7-2 with a 2.61 ERA and he has not lost since May 14 against Oklahoma City.

Marlins No. 30 prospect Gabriel Castellanos tossed the first seven innings of Class A Short Season Batavia's first perfect game. The hurler struck out 12 Mahoning Valley hitters in seven frames before handing over the pitching duties to Brett Lilek and Steven Farnworth, who finished the job without trouble. Wednesday marked Batavia's first-ever 27-up, 27-down performance, not to mention the team's first win of the year. Batavia lost each of its first five games this season by at least four runs. Even Castellanos' greatness was slightly unexpected. He entered the game with a career 7-21 record and 5.15 ERA and gave up five runs (two earned), five hits and two walks in 3 2/3 innings against Auburn to open the year.

Nationals No. 2 prospect (No. 42 overall) A.J. Cole did not earn a decision for Triple-A Syracuse, but he put up a strong line: six shutout innings, three hits, four strikeouts and four walks. The 6-foot-5 right-hander has not won in nine Minor League starts this year, despite posting four quality starts.

Orioles No. 8 prospect Tyler Wilson was another starter who pitched well enough to win. He gave Triple-A Norfolk a solid performance -- seven shutout innings, six hits, one strikeout and no walks -- but Columbus scored four runs in the eighth immediately after his departure. The Tides still won, 5-4, and Wilson has not lost since May 5.

Pirates No. 1 prospect (No. 10 overall) Tyler Glasnow made his second rehab start since spraining his ankle on May 17, giving up one hit and one unearned run while striking out four batters in four innings of work for Class A Short Season West Virginia. That followed a bit of a rough outing on June 19, when Glasnow surrendered three runs (two earned) in 1 1/3 innings. "It felt weird going up and throwing," Glasnow told's Adam Berry after his first rehab start on June 19. "I just haven't done it in so long, just the game atmosphere." It seems Glasnow acclimated quickly and has returned to the form he displayed at Double-A Altoona earlier this season. The 6-foot-8 right-hander was 2-2 with a 2.76 ERA in six starts for the Curve before spraining his right ankle.
