DETROIT -- Nationals pitching coach Steve McCatty is expected to be released from the hospital on Wednesday. The team is hoping McCatty can rejoin the team in Milwaukee.

"They are just being very careful with him, and I'm glad they are doing that," manager Davey Johnson said.

On Sunday, McCatty was transported to a D.C. hospital and was not present for the team's 14-1 victory over the Mets. After the game, Johnson said McCatty was hospitalized with atrial fibrillation. McCatty, 59, had an irregular heartbeat and high blood pressure before Sunday's game.

Like he did against the Mets on Sunday, Johnson took over the pitching-coach duties against the Tigers on Tuesday.

Schu pleased with Nats' approach at plate

DETROIT -- Entering Tuesday's action, the Nationals were hitting .268 since Rick Schu took over the hitting-coach duties. Their best game was Sunday in a 14-1 victory over the Mets. Schu was pleased to see the Nationals score runs without putting the ball into the seats.

"I've been on clubs where it's all or nothing. That's a very tough way to win games," Schu said. "So I think if we can do the little things -- grind at-bats, get hits with runners in scoring position, move some runners … [we] will win some games."

When Schu took over as hitting coach, he designated center fielder Denard Span as a special project. Shu's goal is to return Span to the leadoff spot.

After a slow start, Span was dropped from the leadoff spot to seventh in the order. In his previous two games, however, against the Mets, Span was 5-for-8 with two home runs. Span credits Schu and first-base coach Tony Taracso for getting him into a better position in the batter's box.

"All season, I was real choppy with my swing, and I think the two of them were trying to get me into some rhythm and being more fluid," Span said.

Said Schu about Span: "He is our leadoff-hitter catalyst. I know he is not batting leadoff now. [Bryce] Harper is doing one heck of a job. Denard started as the leadoff guy and he wants to be that guy. He is a competitor. He is one of my favorite guys. I love what he brings. It's about being in good position. He is coming to a new team, he is trying too hard.

"I think he is starting to get his swagger back and trusting it. If he goes, we go, because he is going to be a guy who grinds at-bats, steal some bags, score some runs along with his great defense."

Davey doesn't expect Nats to make any deals

DETROIT -- Manager Davey Johnson said he doesn't expect the Nationals to make a deal by the non-waiver Trade Deadline, which is Wednesday at 4:00 p.m. ET.

The Nationals are looking to acquire a veteran bench player from the left side of the plate. Earlier this month, the team acquired right-handed-hitting Scott Hairston from the Cubs.

With left-hander Ross Detwiler out for at least another month because of a back ailment, Dan Haren being inconsistent and Taylor Jordan on an innings limit, one would think that Washington would like to acquire another starting pitcher.

"I don't think we are going to do anything. We didn't do anything last year," Johnson said. "We have the players we want here. We just need them to do what they are capable of doing. We're fine."

Entering Tuesday's action, the Nationals were in second place with a 52-54 record, nine games behind the Braves in the National League East. They are also 6 1/2 games behind the Reds for the second spot in the NL Wild Card race. The Pirates hold the top spot, 4 1/2 games ahead of Cincinnati.
