DeJesus pleased with right shoulder recovery

CHICAGO -- David DeJesus says he's making progress in his rehab from a sprained right shoulder suffered in a crash into the outfield wall at Citi Field, and also that his parents' heart rate has calmed down.

DeJesus collided with the center-field wall June 14 trying to catch a ball, but ended up with a sprained right shoulder and was placed on the disabled list the next day. He's replayed the video of his crash a few times.

"It's a pretty good one," DeJesus said. "I can still see it in my head, going through the whole thing. The best part is them trying to cart me off. I said: 'No, I'm not getting carted off the field. I don't need my parents worrying even more about what's happening.'"

His parents were panicked at the time.

"Their heartbeats are back to normal now," DeJesus said.

DeJesus also was happy to avoid surgery after the accident.

"It's going to take its time to heal," DeJesus said. "When it starts getting better, we'll move into baseball stuff. Right now, we're getting more movement and it's a positive thing. It's progressing the right way."

Could he return before the All-Star break?

"We're not putting a timetable on anything," DeJesus said. "We'll see how it goes. It's tough just sitting here watching the games. I understand it's a process and I don't want to go out there and get back on the [disabled list] again. I want it to be healthy enough to go hard and get back out there and grind the rest of the season out with the guys."

Garza-Navarro pairing not by design

CHICAGO -- In his last two starts, Matt Garza has given up one earned run over 15 innings. Dioner Navarro was his catcher both games, but Cubs manager Dale Sveum doesn't want to play favorites.

In Garza's five previous starts, Welington Castillo was behind the plate, and Garza went 1-1 with a 6.26 ERA. The right-hander was roughed up in his last outing with Castillo on June 11, giving up nine runs over five innings.

"I'm not going to sit here and say [Navarro] is his personal catcher," Sveum said. "It worked out that way. I really wanted Welly to catch all four games in St. Louis to kind of just be involved with [Yadier Molina], the best catcher in baseball, to see the similarities, to compete against the best guy in baseball, because we want Welly to get to that level, or somewhat near it. I really wanted him to play those four games against the Cardinals, so the schedule panned out to where Navarro would get [Garza]."

Sveum said he can tell Garza is comfortable with Navarro. The two were teammates with Tampa Bay from 2008-10. But Sveum doesn't like the idea of a personal catcher because it sends a bad message to Castillo, who the Cubs consider their No. 1 guy. The Cubs also want Garza to perform at his best.

"When a guy's on the mound, no matter what, it's still whatever you want to call it, it's his game," Sveum said. "That's why starting pitching is where everything starts at and you still want those guys to be comfortable."

If Castillo continues to work four days on, one off, it seems that Navarro will be matched up again with Garza for his next start in Milwaukee.

"I'm not going to lie to you and say it's not a thought [to pair them together], but only if it works out," Sveum said. "I'm not going to put [Navarro] in there for that reason."

Garza can work with other catchers. When he threw his no-hitter July 26, 2010, for the Rays against the Tigers, Kelly Shoppach was the catcher.

Stewart reinstated, Jackson to DL for Triple-A Iowa

CHICAGO -- Third baseman Ian Stewart was reinstated from the suspended list and rejoined the Cubs' Triple-A Iowa affiliate on Saturday.

Iowa also placed outfielder Brett Jackson on the disabled list with a right calf strain, and outfielder Jae-Hoon Ha was promoted from Double-A Tennessee.

On Friday, the Cubs traded infielder Brent Lillibridge to the Yankees for a player to be named later or cash considerations, and on Saturday, left-handed reliever Hisanori Takahashi was dealt to the Rockies for a player to be named later or cash considerations. Both began the season with the Cubs.

Stewart was suspended 10 games for violating the loyalty clause in his contract after he made disparaging comments about the Cubs and manager Dale Sveum on Twitter. He last played June 11 at Oklahoma City and was batting .168 (19-for-113) with six doubles, five home runs and 20 RBIs in 40 games before he was suspended.

Jackson was batting .223 with seven doubles, three homers and 23 RBIs in 61 games. He had an earlier stint on the DL with turf toe.

Ha joins Iowa after batting .284 with one homer, 14 RBIs and eight stolen bases in 28 games with the Smokies.

The Cubs also announced that catcher Steve Clevenger, whose Minor League rehab assignment was to end Saturday, was experiencing some tightness in his oblique area. Clevenger will rest and then be re-evaluated by the Cubs' medical staff.

In 15 games with the Cubs, Clevenger hit .327 with five doubles, three home runs, and 11 RBIs.

Extra bases

• The Cubs dealt left-handed reliever Hisanori Takahashi to the Rockies on Saturday for a player to be named later or cash considerations.

Takahashi, 38, opened the season with the Cubs but after three games was sent to Triple-A Iowa. In 20 games with Iowa, he went 1-0 with a 1.98 ERA, giving up six earned runs over 27 1/3 innings.

• The Cubs will likely make a roster move prior to the start of a six-game road trip against American League West teams. Chicago will travel to Seattle and Oakland, starting Tuesday.

The Cubs are currently carrying eight relievers and are expected to add another position player before the West Coast trip.

• The Elias Sports Bureau says Friday's game, in which the Cubs and Astros combined for four runs all via solo home runs, was the first contest in Chicago's 98 seasons at Wrigley Field in which both clubs combined to score at least four runs and all the runs in the game were scored on solo homers.

• Kevin Gregg has converted 11 straight save chances to begin the season, the second-longest for a Cubs reliever, surpassed only by Randy Myers, who saved his first 13 chances to open the 1993 campaign.

• A group of 24 kids, ages 7-14, will participate Sunday in the Chicago Cubs championship of the 2013 MLB Pitch, Hit and Run (PHR) program presented by Scotts, at Wrigley Field. The top three scores in each age and gender group out of all 30 MLB Team Championships will advance to the PHR National Finals held at Citi Field in New York City during MLB All-Star Week. Pitch, Hit and Run provides youth with the chance to demonstrate their skills and advance through four levels of competition, beginning at the local level.

• The Cubs signed their sixth-round Draft pick, right-handed pitcher Scott Frazier from Pepperdine University. Additionally, the Cubs signed their 17th-round selection, first baseman Kelvin Freeman from North Carolina A&T University. So far, Chicago has signed 13 players from the First-Year Player Draft, including three top-five picks and six top-10 selections.

Frazier, 21, recently completed his junior season at Pepperdine, going 5-5 with a 4.06 ERA and a team-leading 83 strikeouts in 88 2/3 innings. He held opponents to a .237 batting average and allowed just nine extra-base hits. He finished the campaign 2-0 with a 1.29 ERA and 24 strikeouts in his final three starts.
