Padres keeping close eye on Hahn's workload

Combined with Minors, rookie has compiled 110 1/3 innings this season

ST. LOUIS -- In all likelihood, Jesse Hahn will not finish the season in the Padres' rotation.

That notion has nothing to do with the rookie's performance Saturday night, when he surrendered a career-high five runs, but rather a desire to limit the right-hander's innings in his first big league season.

"There's no hard line," manager Bud Black said before Saturday's outing. "[140 innings] might be a little high. Lets put it this way, we're watching each and every start and we'll come to a decision."

Hahn reached 110 1/3 innings across all levels with Saturday's outing. The most he has ever pitched in a season was 69 between Rookie ball and Class A Advanced last year.

"Physically he still feels fine, mentally he's doing great," Black said. "We'll continue to watch his stuff, watch his pitches and see how he's doing. There's six to seven starts left [for everybody], correct? It's probably safe to say that Jesse probably won't make that many starts. How many? We're not ready to talk about that yet."

Shutting down Hahn for good when he reaches a to-be-determined limit is possible, although Black prefers to operate under the philosophy that pitchers continue to get work.

That could mean Hahn sees starts skipped or he could find himself in the bullpen at some point in the season's final six weeks.

"In the past, we've skipped guys, we've pushed them back," Black said. "I think for me, it's good to keep a guy active whether it's in the bullpen or pitching in spots. This time of the year, I don't know whether a complete shutdown is a good thing for him, because I think you have to keep players mentally engaged."

For now, Hahn remains an integral part of the rotation, and he said Saturday his arm felt fine.

"I feel fine," Hahn said. "I'm going to keep going out there every fifth day until I can't pitch anymore."

Solarte returns from two-game injury absence

ST. LOUIS -- Yangervis Solarte has dealt with oblique issues at times during his professional career, but he appears to have avoided the difficult injury this time around.

After being pulled in the seventh inning Wednesday with what was thought to be a mild left oblique strain, Solarte missed the first two games of a four-game set with the Cardinals before returning to the lineup Saturday.

In the end, the injury turned out to be tightness in the lower back, an easier recovery.

"Oblique is difficult to make a swing, but I'm thinking [it's] lower back," said Solarte, who was leading off and at third base Saturday. "I'm feeling good."

In this case, Solarte felt the tightness predominantly when throwing. He took swings without issue, and massaging around the area by trainers allowed him to be medically cleared.

A long-term issue would have been unfortunate timing for Solarte, who hit .300 (6-for-20) in his last six games before exiting Wednesday's contest early.

Worth noting

• The Padres have set their rotation for the upcoming three-game series with the Dodgers in Los Angeles. The team will send Ian Kennedy to the mound Tuesday followed by Eric Stults on Wednesday and Tyson Ross in Thursday's finale.

• First baseman Yonder Alonso, who exited Tuesday's game with a right forearm strain, was examined by doctors and a hand specialist in San Diego on Saturday. The team expects to have more information on his prognosis Sunday.

• Outfielder Cameron Maybin, who was suspended 25 games in July after testing positive for amphetamines, must be activated by the team Wednesday, manager Bud Black said. Maybin made an appearance at Triple-A on Friday, his first since the suspension, going 0-for-1 with a pair of walks.

• Joe Wieland, who is recovering from right elbow surgery in March, made his first appearance at Triple-A on Friday, tossing six innings on 68 pitches while allowing two runs. Wieland has now made six Minor League appearances.
