• Travis d'Arnaud got whacked in the arm by a Cubs backswing Friday night, and although it's not a concussion like he suffered in May, these workplace injuries special to catching are worrisome for the Mets.
"Right now he's OK. We are concerned about this. This guy has had one concussion, three in his career," Collins said. "We have to make sure this guy stays healthy because his bat is going to play, as we've seen. You can't keep losing this guy for seven days every month."
• Matsuzaka tossed six strong innings for Double-A Binghamton in his second rehab start Saturday. He outpitched Jesse Biddle, the Phillies' No. 4 prospect, by limiting the Reading bats to one run on three hits, striking out three and walking none. Matsuzaka threw 43 of his 69 pitches for strikes.
