Ailing hand keeps Hamilton out of lineup for second day

CINCINNATI -- Injured Reds center fielder Billy Hamilton is going to great lengths to get back on the field, but was out of the starting lineup again Saturday.

The speedy rookie sprained two knuckles on his left hand making a diving catch in the first inning of Thursday's series opener against Milwaukee. Hamilton said on Saturday he still could not grip the bat, but would be available to pinch-run and, optimistically, as a defensive replacement.

"I've got two gloves now," Hamilton said. "The one I usually use is pretty hard. The other one is softer."

Hamilton also has finger guards, fashioned by Reds trainer Paul Lessard, to prevent his fingers from bending back when he slides. Umpire Joe West told Hamilton that the guards were too long during a game against Chicago, but Hamilton said the gear has since been checked out and approved.

Schumaker activated from disabled list

CINCINNATI -- Reds utilityman Skip Schumaker, sidelined since late in Spring Training with a dislocated left shoulder, was activated from the 15-day disabled list on Saturday.

Cincinnati's versatile infielder/outfielder had been on a Minor League rehab assignment with Triple-A Louisville since Monday. He was injured during a March 21 game while attempting to make a diving catch in the outfield.

"I think I'm ready for it," Schumaker said. "I haven't tested it [by diving for a ball] yet, but we'll see what happens. I'm not as worried about it as I was a few weeks ago."

Schumaker signed a two-year, $5 million contract as a free agent during the offseason to be a backup outfielder and second baseman.

"It was tougher, being a new guy," Schumaker said. "You want to make a good impression on the guys, the management. To have it happen that late in Spring Training was pretty frustrating."

The Reds made room for Schumaker on the 25-man roster by designating outfielder Roger Bernadina for assignment. Bernadina, 29, was batting .143 (4-for-28) and was 1-for-11 as a pinch-hitter.

"I haven't really gotten into a groove," Bernadina said. "I was a little surprised, but I understand. I knew Skip was coming back. We'll wait a couple days and see what happens from there."

Chapman works clean frame in second rehab outing

CINCINNATI -- Reds hurler Aroldis Chapman moved closer to returning from the disabled list Saturday when he pitched a scoreless first inning for Class A Dayton, his second Minor League rehabilitation appearance.

Chapman threw 16 pitches. He struck out Lake County's Clint Frazier swinging and induced a popup from Claudio Bautista. Chapman walked No. 3 hitter Dorssys Paulino, but picked off Paulino to end the inning.

The two-time All-Star is likely to make one or two more appearances before being activated.

Thursday marked Chapman's first game action since March 19, when he was struck in the head by a line drive off the bat of Kansas City's Salvador Perez in a Spring Training game. Surgery was required to repair fractures near his nose and left eye.

Mesoraco making strides in hamstring recovery

CINCINNATI -- Devin Mesoraco said he is scheduled to jog in the outfield on Sunday, but manager Bryan Price said the team will proceed cautiously with their catcher, who has already made two trips to the disabled list this season.

"I've been doing some strengthening and some stretches and everything feels fine," Mesoraco said on Saturday. "I got some throwing in today and we'll do some [jogging] tomorrow and, hopefully, some running soon."

Mesoraco was placed on the 15-day disabled list on April 26 with a strained left hamstring. He had previously been on the DL until April 7 with a strained left oblique.

"There is not a day [scheduled] yet for running bases or anything like that," Price said. "We don't want to be too aggressive."

Mesoraco has been productive when healthy, hitting .468 in 47 at-bats with six doubles and three home runs.

Worth noting

• Some of the Reds' personnel were a bit taken aback when the first statistics posted from injured closer Aroldis Chapman's rehab start Saturday for Class A Dayton showed he had pitched three innings vs. Lake County. In fact, Chapman had thrown only one.

"I wondered what had happened," Cincinnati manager Bryan Price said. "I thought maybe Aroldis had talked [Dayton pitching coach] Tony Fossas into letting him throw another inning or two."

• Price said injured third baseman Jack Hannahan (shoulder) has been hitting off a tee and may begin taking live batting practice in another four or five days.

"He's in a much better place than he was when we left Goodyear," Price said.
