NEW YORK -- An MRI on Daniel Murphy's left quad Thursday revealed only a "mild strain," according to a team spokesman. Murphy is day-to-day.
Murphy, 30, left Wednesday's 9-4 win over the Phillies due to discomfort in his quad, saying afterward that it felt "just a shade less than 100 percent." The Mets, at the time, termed his removal a precaution.
One of the Mets' most consistent offensive threats this season, Murphy is batting .282 with 10 home runs in 107 games. He has been starting at first base with Lucas Duda on the disabled list, but he figures to shift back to second once Duda returns.
• The Mets announced that left-handed reliever Dario Alvarez will join the team in time for Friday's game in Miami. Alvarez, 26, had a 2.45 ERA at Triple-A Las Vegas, and, considering Eric O'Flaherty's struggles, is a legitimate candidate to make the playoff roster as a lefty specialist.
