■ SCORE: Cardinals 15, Red Sox 4.
■ RECORD: 2-3.
■ BREAKDOWN: After Ryan Dempster’s two scoreless innings, Red Sox pitching went south. Clayton Mortensen was touched up for three runs on two hits in two innings. Jose De La Torre allowed four hits and five runs in one inning, and Pedro Beato gave up four runs and four hits in one-third of an inning. The Sox committed three errors in taking their worst beating in spring training so far.
■ THUMBS UP: Dempster threw strikes in his Sox debut. “Threw the ball well,” said manager John Farrell. “Established his fastball and showed a good split. It was clean, he did a great job controlling the running game.” . . . There was not much else to crow about. Drew Sutton had two hits and reached base three times. Lyle Overbay tripled, and Ryan Lavarnway doubled in a run. Jose Iglesias also doubled.
■ THUMBS DOWN: Usually sure-handed second baseman Jonathan Diaz committed two of Boston’s errors. While Anthony Carter’s line didn’t look good — he gave up three runs, none earned — Farrell continued to praise his stuff.
■ MEDICAL REPORT: Clay Buchholz (hamstring) threw a successful second simulated game and is now on track to face the Twins Saturday . . . Mike Napoli (hips) will continue his running program Wednesday and play in a game this weekend . . . David Ortiz (Achilles’ tendon) has been taking fielding practice, but he is about a week behind Napoli. Ortiz wants to take things slowly with his heel starting to feel closer to 100 percent.
■ AROUND THE BASES: Ex-Sox third baseman Mike Lowell came to camp to work with Will Middlebrooks on his footwork and throwing. Lowell came on the invitation of second baseman Dustin Pedroia, who enjoyed a great relationship with Lowell on the field . . . Jackie Bradley Jr. went 1 for 3 and tracked the ball well in the outfield. He is opening eyes . . . 1B/OF Mark Hamilton hit two long drives. One was caught and the other went off the wall for a double.
■ NEXT GAME: Wednesday at Sarasota vs. the Orioles at 7:05 p.m. The Sox will start lefty Franklin Morales, followed by Drake Britton, Junichi Tazawa, Joel Hanrahan, Koji Uehara, Andrew Bailey, and Andrew Miller. The Orioles will start lefty Zach Britton.
