Choo continues to deliver in leadoff spot

CINCINNATI -- Reds center fielder Shin-Soo Choo hit his 15th home run of the season on Saturday night, but it was his first with runners on base. That's often the way it goes for leadoff hitters, but manager Dusty Baker said Choo has made the most of the opportunities he's had to put runs on the board this season.

"If my leadoff man can have 50 RBIs and 100 runs at the end of the year, he's going to be very, very productive in our league," Baker said. "Choo's on pace to get that and more."

Entering Sunday with 35 RBIs and 73 runs scored, Choo is on track to drive in just barely more than 50 runs and score a shade under 110. With the limited chances he has had to bring runners home, Choo, who has more home runs than any other leadoff hitter this year, has done well. In 93 plate appearances with runners in scoring position before Sunday, Choo was batting .234 with eight doubles and 19 RBIs, and Baker said his numbers would be even better if he wasn't at the top of the lineup.

"He's one of our best hitters with runners in scoring position," Baker said. "It's just where he's hitting ... because the bottom of the order wasn't getting on for a while. It's better now."

Mesoraco making strides with bat, behind plate

CINCINNATI -- Devin Mesoraco's recent offensive surge, including his first career multi-home run game on Saturday, is what the Reds have expected all along from him at the plate. Behind it, the 25-year-old catcher is still a work in progress.

With Ryan Hanigan on the disabled list since July 11, Mesoraco has handled the majority of the catching duties and taken advantage of the opportunity by batting .333 with four homers and 12 RBIs in his last 15 games, including 12 starts, entering Sunday. But when manager Dusty Baker watches Mesoraco, he's looking at much more than offensive production.

"There's a lot of stuff that goes into being a catcher," Baker said. "It's the toughest position on the field -- mentally and physically. You can't take that strikeout with the bases loaded out on the field, and vice versa, you can't take a bad inning to the plate."

When it comes to catchers, Baker said more often than not a player will excel offensively or defensively, but rarely are they elite in both aspects. However, he hopes Mesoraco, who first played for the Reds in 2011 after being the club's first-round Draft pick in 2007, can be one of the exceptions.

Although he didn't want to compare Mesoraco to anyone specifically, Baker pointed to injured Cardinals backstop Yadier Molina as an example of the progress a catcher can make. Known for his defensive abilities since he broke into the Majors in 2004, Molina gradually improved his bat and was hitting .330 as one of the key pieces in the St. Louis lineup before going on the disabled list at the end of July.

After playing 54 games last season and 18 the year before, Sunday marked Mesoraco's 70th appearance in 2013. Baker said Mesoraco has improved in all facets of the game since last season, but he also expressed the importance of being patient with young catchers.

"It takes a while," Baker said. "And by the time a catcher is 100 percent ready, usually you only get two or three years out of them and they're broken down."

Worth noting

• Ryan Ludwick continued to struggle while on his rehab assignment on Saturday, going 0-for-5 for Triple-A Louisville. In eight rehab appearances, Ludwick entered Sunday going 2-for-24 (.083) while he works his way back from a torn labrum in his right shoulder that he suffered on Opening Day.
