Jenkins, 20, made 10 starts for Class A Peoria before being promoted to Palm Beach in mid-June. He's allowed five earned runs on 13 hits in 10 innings since the move.
• Left-hander Sam Freeman has run his scoreless-appearances streak to 14 games (23 1/3 innings) for Triple-A Memphis. During the scoreless streak, Freeman has scattered 14 hits and 11 walks.
• Memphis first baseman Brock Peterson was one of six Triple-A All-Stars to be selected to participate in the upcoming Triple-A All-Star Home Run Derby. Peterson leads the Pacific Coast League with 20 home runs.
• Left-hander Tyler Lyons earned Pitcher of the Week honors (July 1-7) in the Pacific Coast League after making a pair of quality starts for Memphis last week. Lyons allowed three runs on four hits in 15 innings. He struck out 18, walking only three. Since returning to the Memphis rotation after a stint in St. Louis, Lyons has limited opponents to five hits in 69 at-bats.
"We talked since his return back down there, it's all about fastball execution," said Johnson, who caught Lyons in the Minors. "There's no doubt that his breaking stuff is very good, but to compete at this level, I think you have to execute your fastball better. And I think that's what he's really been concentrating on. He's done an excellent job of that these last two outings."
• Double-A Springfield catcher Audry Perez was named Texas League Player of the Week after going 7-for-14 with two homers, a double, seven RBIs and three runs scored from July 1-7. He is the fourth Springfield player to win a weekly league honor this season.
