SAN DIEGO -- Odubel Herrera has missed the Phillies' last two games with a sore left hamstring and the team could sure use his bat.
Will he be available Thursday in San Francisco?
Herrera was asked about his condition as he hurried out of the clubhouse and off to the team bus after Wednesday's 3-0 loss to the San Diego Padres (see Instant Replay).
"Better," he said, indicating some improvement.
Could he play in the next day or so?
"Maybe," he said.

As a contingency, the Phillies will add a position player - Brock Stassi makes sense - to their roster for Thursday's game while they continue to evaluate Herrera. If Herrera can't go in a couple of days, he could end up on the disabled list. He injured the hamstring late in Monday night's game. He improved his hitting streak to 17 games earlier that night.
In order to add a player to the roster without placing Herrera on the DL, the Phillies had to clear a roster spot. They took the unusual step of sending Nick Pivetta to Triple A moments after he struck out a career-high 11 batters on Wednesday.
It appears to be simply a procedural move. The Phillies play a doubleheader Tuesday against Miami and will be allowed to add a 26th man that day. Ordinarily, a player sent to the minors could not return for 10 days unless he replaces an injured player. By rule, Pivetta could come back and be the 26th man on Tuesday. He then would have to return to Triple A to complete the 10-day stint in the minors. The bottom line is he might not even miss a turn in the major-league rotation.
"With Herrera on the blocks, not knowing where he's at, we need a position player," Mackanin said. "With the doubleheader coming up, we have the option of adding an extra pitcher on the 22nd. So that's the reasoning there."
Pivetta took the move in stride.
"It is what it is," the 24-year-old righty said. "I know about as much as you guys. I'm going to go down and work hard. It will be fine. I'm going to be back up eventually. So we'll just keep moving day by day there."
Pivetta struck out eight of the first nine batters he faced on Wednesday. When the ninth batter, rival pitcher Clayton Richard, came to the plate, he asked catcher Cameron Rupp a question.
"Did he strike everybody out?" Richard asked.
Richard struck out, but eventually got the upper hand. He pitched a three-hit shutout to finish off a San Diego sweep.
"It looked to me like Pivetta was going to have a Kerry Wood performance today," Mackanin said. "Eight strikeouts in the first three innings. He ended up with 11. He threw a lot of good secondary stuff for strikes, which is one of the goals we're working on for him to do. He carried it for a while. He needs to understand how to continue to carry that through five, six, seven or even eight innings.
"He's a young pitcher. It's his first year in the big leagues. He's going to get it. He's going to be good. He needs to learn how to sustain that through more than five or six innings. That's when you get to be a real solid starter."
