Getting defensive: Reds slugger Adam Dunn's diligence this spring to get better as a hitter has already drawn praise. But Dunn's commitment to becoming an improved left fielder defensively has drawn raves, too.A 40-home run hitter the past three seasons, Dunn has been considered below average in the field, and he committed 13 errors last season. Throughout camp, he has spent extra time on the back fields with coaches Billy Hatcher and Ed Napoleon going over the finer points of outfield defense -- like going back on balls, reading balls hit off the bat, taking a quicker first step and better throwing techniques. "He was dedicated, but he didn't put in the time to get better," Hatcher said of Dunn's effort last season. "That's one thing with baseball. The more years you get, the harder you have to work. He didn't work as hard defensively last year, and it showed. He came here the first day of Spring Training and wants to get better. He's out here working. He's doing everything. He wants to be an all-around ballplayer, so he's putting in the time to get better." In a challenging second-inning play vs. New York, Dunn couldn't come up with Jorge Posada's drive to the warning track in spite of a diving attempt. Posada picked up a double on the play. Hamilton hit ticker: Rule 5 pick Josh Hamilton continued his productive spring Tuesday by going 2-for-2 with two RBIs, a sacrifice fly and a walk as the center fielder. That raised Hamilton's average to .571 (16-for-28). In the first inning, Hamilton got an RBI single off Mike Mussina with a roller through the right side. After a sacrifice fly to left field in the third, Hamilton reached on a squib to second base against Mariano Rivera. Robinson Cano's difficult throw sailed over first base, but Hamilton was credited with a hit. Before the game, Reds manager Jerry Narron was asked if he'd have any concern about using Hamilton in the regular season if the 25-year-old made the team. "I wouldn't be afraid to," Narron said. "The one thing that has surprised me more than anything about him in a very good way has been his plate discipline. The layoff, three years really, to have that kind of plate discipline is impressive. I know it's early in spring and we haven't seen a guy like Mike Mussina at his best. [Hamilton] does not go up there like he's in any kind of hurry or rush or panic or anything. He's in control and knows what he's doing." Coming up: Bronson Arroyo will get his second Grapefruit League start when the Reds host the Devil Rays in Sarasota Wednesday at 7:05 p.m. ET. Top prospect Homer Bailey will also see action. Edwin Jackson is Tampa Bay's scheduled starter.
