MIAMI -- Last May's Marlins-Nationals series was a Solano family affair, as Washington's Jhonatan and Miami's Donovan met on the same big league diamond.
Donovan had become the 12th Colombian to reach the Majors, while his older brother soon followed on May 29 in Miami.
Jhonatan said the pair talks every other day about each other's games and life in baseball. Their parents, who made the trip from Colombia last year, have been in attendance for the weekend series.
"It's an unbelievable feeling playing versus your brother in the big leagues." Jhonatan said. "We're living the dream right now."
Recalled Aug. 23 from Triple-A Syracuse when Kurt Suzuki was dealt to the A's, Jhonatan hopes to make the most of his return.
The 28-year-old helped secure Wednesday's 3-2 win for the Nationals by blocking a tough pitch and tagging out Chase Utley, who tried to score. He is batting .189 with two RBIs over 40 plate appearances and 19 games.
"Getting back here is awesome," Jhonatan said. "I waited for the opportunity and now I'm here enjoying the time with my teammates. I feel part of the team right now. It's exciting, and I'm here -- ready to help the team win."
Jhonatan entered Saturday's game in the seventh inning as a defensive substitution. He flied out to right in the eighth. Entering Sunday's finale, brother Donovan has gone 2-for-8 with a run as Miami's starting second baseman.
Detwiler throws encouraging bullpen session
MIAMI -- Nationals left-hander Ross Detwiler threw 20 pitches -- all fastballs -- in his first bullpen session since landing on the disabled list in July.
The 27-year-old, who was shut down for 30 days with a herniated disk in his lower back, tossed both his four-seam and two-seam fastballs. He said that all but one hit the corners of the plate.
"I think it's like at Spring Training, because I felt strong for all 20. But there's a reason they stopped me at 20," Detwiler said. "That was the plan going in. I think they know a little better about building people up than I do. If it was up to me, I would've gone until I couldn't stand up anymore and see where I'm at then."
Detwiler's next bullpen will be on Wednesday in New York, where he will add 10 more throws that will include all of his pitches.
Before landing on the DL on July 4, Detwiler was 2-7 with a 4.04 ERA in 13 starts over 71 1/3 innings. He hopes to make an appearance before the season ends.
"I can always say I'm feeling good," said Detwiler. "But for all the coaches to be out there and see it, it shows them how I'm feeling and also shows myself that I can still locate after two months."
Davey tries to pick his spots with callups
MIAMI -- Balancing September callups and a postseason chase can prove to be a challenging act.
Washington entered Sunday's series finale against the Marlins eight games behind the Reds for the second National League Wild Card spot with 21 games remaining.
"[I want to] get them some experience up here and get a better read on how they fit in our future," Nationals manager Davey Johnson said. "We have pretty much a set lineup, so you're looking at guys who are bench players -- not anybody that's going to beat anybody I've got on this ballclub."
Friday night's 7-0 loss offered Johnson the chance to utilize five relievers. With a big lead on Saturday, he inserted Eury Perez, who has shown his speed tracking balls in the outfield, as a defensive replacement. He caught a Logan Morrison liner for the second out of the ninth in Saturday's win.
Though he wants to give some prospects a taste of the Majors -- like Zach Walters pinch-hitting appearance on Friday -- winning won't be compromised.
"I'm still using the players I think are best suited for us to win a ballgame," Johnson said. "By the same token, I have in mind that these guys are up here to reward [them] for a good year, and they're our top prospects. So when the situation arises, I'll definitely get them in there."
