Logan Morrison led off with a single and stole second. Dobbs’ sinking liner to left-center with one out was initially ruled a diving catch by Alex Presley. But the umpires conferred after Miami manager Ozzie Guillen came onto the field to argue, and they ultimately awarded Dobbs a single.
But Morrison remained at second base, thinking he needed to tag. The Marlins pleaded their case to no avail, and Omar Infante grounded into a double play on the next pitch to end the inning.
Sanchez (5-7) allowed three earned runs in his previous two starts. McCutchen had an RBI single in the first, but Sanchez was cruising again until the seventh.
Miami (44-51) is a season-worst seven games under .500.
