Matt Harvey had the first subpar outing of his major league career Sunday afternoon. The 2010 first-round pick surrendered five runs on eight hits in five innings and the Mets completed their 11-game West Coast trip with a 7-3 loss to the San Diego Padres.

Harvey is scheduled to make his Citi Field debut on Friday night.

The Mets are off Monday before welcoming Jose Reyes and Marlins to Citi Field for a three-game series. Reyes has a career-high 24-game hitting streak, the longest in the majors this season.

Tim Byrdak is due to get an MRI to help determine the extent of the damage to his left shoulder today. There may be word as well whether Kirk Nieuwenhuis requires surgery for the plantar fascia tear in his right foot, which he suffered with Buffalo.

Monday’s news reports:

• Johan Santana tossed three scoreless innings in a rehab start for Brooklyn on Sunday night. Terry Collins expects the 33-year-old left-hander will be activated from the DL on Saturday to face the Braves. Santana threw 38 pitches (29 strikes) while surrendering one hit and one walk and striking out three. He upped his pitch count to 90 by throwing in the bullpen at Coney Island afterward. Santana landed on the DL with a right-ankle sprain, although team officials believe that contributed to shoulder fatigue. Jeremy Hefner should find himself in the bullpen for the Marlins series with Santana ready to rejoin the rotation.

"My whole right side feels good," Santana told Stephen Haynes in Newsday. "Even though my ankle was what was bothering me, I was able to rest my whole body. That's something I really needed."

• The Mets finished their three-city trip with a 6-5 record. Read Sunday's game recaps in the Post, Times, Journal, Star-Ledger, Daily News, Record and Newsday.

• Jason Bay went 2-for-31 on the road trip. He could start Tuesday when the Mets face Marlins left-hander Wade LeBlanc, but Bay's playing time now may greatly diminish. Read more in Newsday.

• Zack Wheeler did not make his Triple-A debut for Buffalo on Sunday due to a rainout. Instead, he will pitch the opener of a doubleheader on Monday at 5 p.m. at Syracuse.

• Collins said it would be helpful to have a second lefty in the bullpen along with Josh Edgin for next weekend's Braves series with Byrdak sidelined. That likely would mean the addition of Robert Carson. But the Mets also need to activate Santana next weekend, so they would need to subtract a second pitcher beyond Elvin Ramirez for Collins' desire to materialize. Read more in the Daily News.

• Right-hander Scott Patterson joined the Mets organization and was activated by Buffalo. Patterson asked his released from the Mariners, where he was working in relief in Triple-A but was bypassed for a major league promotion.

• Richard Lucas went 3-for-5 with a homer and three RBIs as St. Lucie beat Fort Myers, 9-1. Read Sunday's full minor league recap here.
