McCarthy played catch Saturday, although it is unknown if he will be able to swing a bat Sunday.
Rich Hill, on the disabled list most of this season with a finger blister, threw a bullpen session Saturday and Roberts said he is scheduled to pitch five innings or 75 pitches in a Tuesday rehab start. Hill was yanked from a Thursday rehab start during a 29-pitch first inning.
So far, however, Hill said the finger is holding up without a blister flare-up. He said if the rehab start goes well, he is close to returning to the club, although Roberts said that means he needs to get batters out efficiently Tuesday to show he's ready.
"Rick [Honeycutt, pitching coach] said it was good, not great, but the finger came out of it great," said Roberts. "A little bit of the message is, if you're one start from making a Major League start, you've got to get guys out."
Roberts said Hyun-Jin Ryu, who will miss one start on the disabled list with a sore hip, will return without the need of a rehab start. He is eligible to return Thursday.
