Red Sox LHP Brian Johnson, Double-A Portland: 6 IP, 4 H, BB, 5 K — The 23-year-old is 5–1 with a 1.71 ERA through eight Double-A starts. This was his first scoreless outing, though, and improved his strikeout-to-walk ratio to 45-to-14.

Cardinals INF Mason Katz, Class A Peoria: 2-for-5, 2 HR, 2 RBI, 2 R, K — Katz hit a walk-off winner in the bottom of the 10th inning to give the Chiefs a win. The 23-year-old has some good raw pop and now has 11 homers on the season, but he’s also still batting .209 as a college product

Rangers OF Jairo Beras, Class A Hickory: 3-for-5, HR, 2 R, RBI, BB — The homer was Beras’ first in the South Atlantic League, and the three-hit game brought the big-money international free agent up over the Mendoza line to .201.

Cubs SS Javier Baez, Triple-A Iowa: 2-for-4, HR, 2 RBI, R, 2 SB — Baez snapped an 0-for-19 slump Sunday, belting his 10th home run and driving his stolen base totals up to 11.
