PHOENIX -- The D-backs swapped a pair of relievers with Triple-A Reno, the team announced on Tuesday.
Coming to Arizona are right-hander Yhency Brazoban and left-hander Alberto Castillo, while right-handers Esmerling Vasquez and Bryan Shaw head to Reno.
"The biggie is that we wanted to get a second left-hander, for sure," D-backs manager Kirk Gibson said. "I've been talking about this portion of the bullpen, so [general manager] Kevin [Towers] thought that this [was] the direction we needed to go in. So we'll see how it works out."
Both pitchers were signed as Minor League free agents earlier this month.
Brazoban has not pitched in the Major Leagues since 2008 with the Dodgers. He had a 2.70 ERA with 11 strikeouts in 10 innings at Reno.
- 131 wins
- 121 wins
"He's got experience in a lot of situations," Gibson said. "Good velocity, and throws strikes."
He has a career 4.70 ERA in parts of five Major League seasons.
"I feel pretty happy about coming back to the big leagues," Brazoban said. "I'm going to do whatever I can to help the team."
The 35-year-old Castillo pitched parts of three seasons with the Orioles, and recorded a 4.15 ERA. He posted a 1.50 ERA, with nine strikeouts and three walks, in three games with Reno.
"I came here to do my job, and I'll be ready any time they need me," Castillo said. "That's what I'm here for."
Pena comes through as pinch-hitter
PHOENIX -- Wily Mo Pena knew his role.
"I was just thinking to get on base," Pena said about Monday night's pinch-hitting appearance in the bottom of the eighth against Indians reliever Vinnie Pestano.
"Just trying to get a hit so somebody could drive me home."
Pena did get a hit -- a single up the middle -- and somebody did drive him home. Kelly Johnson followed one batter later with a triple to right-center field to tie the game.
Pena's single came in his first pinch-hit at-bat since May 4, 2008 -- when he hit an RBI double as a member of the Washington Nationals -- and broke a six-inning hitless streak for the D-backs against Indians pitching.
"I've been through it before," Pena said. "It wasn't different."
Pena was frequently used as a pinch-hitter during the first four years of his career with the Reds.
"It's not hard," he said. "I know people say it's hard to get used to pinch-hitting. But when I came up, they used me a lot for it. So that's why, over the years, I've just told myself to do the same thing you used to do before."
In 24 at-bats with the D-backs over seven games this season, Pena is hitting .208 with a pair of home runs.
Blum hopes to return near All-Star break
PHOENIX -- Injured infielder Geoff Blum was in the D-backs' clubhouse on Tuesday afternoon.
"I'm here today," he joked. "Walked in on my own power."
Blum played half a game on Monday in the Arizona Rookie League, and looks to increase his workload on Wednesday, Friday and Saturday before making the jump to Triple-A Reno.
"They're still working on a timetable for that -- but hopefully sooner, rather than longer," he said. "I feel pretty good."
Blum signed with the D-backs as a free agent in the offseason. He underwent surgery on his right knee in April, and has been shelved on the disabled list since.
"We had an idea of what he would be coming in, but we have to see exactly how far back [toward] 100 percent he can get," D-backs manager Kirk Gibson said. "I think that would kind of determine how he fits in, and how we'll use him."
Blum has a career .251 average in 12 seasons as a Major League player.
When asked if Blum could be ready near the All-Star break, Gibson answered, "I hope so."
