CHICAGO -- During a seminar at the Cubs Convention in January, Starlin Castro was asked whom he idolized in baseball and he picked Miguel Tejada, now with the Giants.
"Last year, I told him, 'Hey, you're my favorite player,'" Castro said.
Tejada and Castro, both from the Dominican Republic, had a chance to chat Saturday prior to the Cubs-Giants game.
"He asked me a lot of questions about the game, how he could be better," Tejada said. "I'd love to help him."
It's not the first time a young shortstop has reached out to Tejada. Hanley Ramirez and Jose Iglesias also have asked for advice.
"It makes me feel good and proud of myself when you see all those young guys who can be superstars of the future and they want to get information," Tejada said.
Tejada, 36, told Castro he'd give him a video about defense.
"I want to see how he plays," Castro said.
"He's asked me how to stay in the big leagues for a long time," Tejada said. "He's a really smart kid. I was the same -- when I was young, I asked a lot of questions. Because in this game, you never stop learning. That's probably why he's like that.
"What I like about him is his energy," Tejada said. "He can play defense, he can hit -- I think the best part about him is his hitting. I think he's going to be the guy of the future on that team."
Entering Saturday, Castro, 21, was batting .588 (10-for-17) in his last four games after going 2-for-25 in his previous six. His 52 hits this season rank tied for second in the National League and are third most in the Majors.
Tejada is right. Castro can hit. Thanks to Tejada, Castro may become a better defensive player.
"He's a good person, too," Castro said of the veteran.
Perseverant Davis back in Majors with Cubs
CHICAGO -- Left-handed pitcher Doug Davis was added to the Cubs' roster Saturday in time to start against the Giants.
The Cubs selected his contract from Triple-A Iowa and optioned right-handed pitcher Justin Berg to Iowa. In a separate move, the Cubs outrighted right-handed pitcher Thomas Diamond off the 40-man roster to the Iowa roster. The Cubs' 40-man roster stands at 39.
Davis, 35, had stopped by the Cubs clubhouse Friday and met manager Mike Quade for the first time.
"It's got to be [weird]," Quade said. "In my brief five-, 10-minute conversation -- and I'd never met him in my life -- he was good. When you have all that experience to fall back on, you understand this is part of the game.
"I got a kick out of how excited he was, given all that he's done and how long he's pitched and everything else," Quade said. "To be here, starting in Wrigley, he was really excited about it."
Davis started eight games last year for the Brewers, his last on July 9. He was then sidelined because of left elbow tendinitis.
"He's not a spring chicken, so this is a big deal for him," Quade said. "It says a lot about fortitude and staying after something and 'I'm going to pitch until I realize I can't.'"
Davis is 91-101 with a 4.38 ERA in 297 appearances (277 starts) covering all or part of 12 Major League seasons with Texas (1999-2003), Toronto (2003), Milwaukee (2003-06, 2010) and Arizona (2007-09).
Colvin's lack of at-bats a quandry for Quade
CHICAGO -- A year ago, Cubs outfielder Tyler Colvin played 22 games in April with 45 at-bats and was hitting .289. He played another 23 games in May, and hit .333 that month.
This year has been different.
"It's been awful for Tyler," Cubs manager Mike Quade said Saturday.
Colvin played 21 games this April with more at-bats (51) than a year ago but hit .137. This month, he's totaled 11 at-bats in seven games and is hitless.
"I haven't been able to find as many [at-bats for him] as I want," Quade said. "Other people are as responsible for that as Tyler. He's struggled for sure, but with our outfield playing the way it is, I've got a guy sitting on the bench who's tearing it up right now in Reed Johnson. [Colvin] understands his role as a bench guy but you want to keep him involved as well."
Alfonso Soriano, Marlon Byrd and Kosuke Fukudome all have played well, which has made it tough to squeeze in an at-bat for Colvin. Johnson has played in 25 games this season but he's hitting .405.
"It's a heck of a balance every day to try to keep [Colvin] involved and get him to where he was last year and contribute on that level," Quade said. "You're also trying to win ballgames and do justice to the other guys who are hitting. It's the worst part of my day [trying to determine what to do with Colvin]. The five guys who aren't playing bother me more than anybody else. That's been a really tough situation for Tyler."
Asked if he's considered sending Colvin to the Minors to get more regular at-bats, Quade said: "We need to get him involved some way, somehow, and that's been on my mind the last few days. We'll see how this homestand plays out and take a look at that."
Geovany Soto, on the disabled list with a strained left groin, was able to play catch Saturday and is headed to Mesa, Ariz., to continue his rehab at the Cubs' facility. Soto was injured in the first inning May 10.
Aramis Ramirez was scheduled to rejoin the Cubs on Saturday night. He had returned to the Dominican Republic to attend to a personal matter.
Reed Johnson hasn't had many at-bats but he's made the most of his appearances.
"Overachieving, gamer -- pick the description of him," Cubs manager Mike Quade said of Johnson, who was hitting .405 in 25 games and doubled his RBI total Friday when he drove in four runs. "Right now, he's also swinging the bat real well. He's always been a quality defensive guy."
Outfielder Kyung-Min Na was added to the Cubs' Double-A Tennessee roster and Jim Adduci was placed on the disabled list. Na, 19, has been in the Cubs' extended spring training camp. He hit .208 with four doubles, one triple and 11 RBIs in 66 games with Class A Boise last year. Adduci was hitting .340 with seven doubles, two homers and 11 RBIs in 32 games.
The Cubs' June 19 game against the Yankees at Wrigley Field will be part of the ESPN national broadcast and begin at 7:05 p.m. CT.
Marlon Byrd extended his hitting streak to a career high-tying 15 games with an infield single in the fourth. He is batting .362 in that stretch. Byrd set the 15-game mark from July 20-Aug. 2, 2003, when he played for the Phillies.
Saturday's game was the Cubs' first rain-shortened game since a five-inning contest May 26, 2009, vs. the Pirates.
