SAN DIEGO - With big hit after big hit, Tony Clark’s status as the most efficient run producer in the major leagues has seemed obvious, and now it has been confirmed statistically.
Through Friday, Clark had driven in 15.2 percent of the runners on base when he batted, ahead of Cubs Triple Crown candidate Derrek Lee (14.7 percent) and Milwaukee’s Carlos Lee (12.9 percent), the NL’s RBI leader, according to John Dewan’s Stat of the Week.
"The consolation prize that I take from that is that I’m doing my job,’’ Clark said. "My job is to get guys across the plate.’’
Houston’s Morgan Ensberg was third (13.2), between the Lees, while St. Louis’ Albert Pujols (12.5) rounded out the top five.
Dewan based his calculations on the number of RBIs possible if a player homered each time at bat. For example, if the bases were loaded he would have four opportunities.
Clark had 48 RBIs in 174 atbats. Carlos Lee had 77 RBIs in 346 at-bats.
With his pinch-hit, RBI single Friday, Clark has 12 pinch hits, within reach of Carlos Baerga’s team record of 19 set in 2003.
Right fielder Shawn Green, hearing that the D-Backs have discussed moves that could result in his shift to center field, said he would be fine with that.
"Whatever they want me to do,’’ said Green, who quietly has become the team leader with 97 hits while improving his batting average to .290. "It would be easier than moving to first base like I did last year.’’
The D-Backs have discussed the possibility of promoting top prospects Conor Jackson or Carlos Quentin from Tucson if an offensive jolt is required, and the subsequent shuffling would include Green’s move to center field.
D-Backs scouting director Mike Rizzo and general manager Joe Garagiola Jr. met with No. 1 overall draft pick Justin Upton and his representatives during the All-Star game in Detroit.
"There was not much movement,’’ Rizzo said.
The Upton family was in Detroit to watch B.J. Upton, a Tampa Bay prospect who played in the Futures Game. Adviser Larry Reynolds, who also represents B.J., was present.
The D-Backs gave last year’s first-round pick, Stephen Drew, a $4 million signing bonus on a major league contract worth $5.5 million, and it is believed the Upton camp would like to be in the same neighborhood, although Drew was a college junior when he signed and Upton a high school player.
The D-Backs have signed all of their first 25 draft picks except Upton and No. 11 Brett Jacobson, a right-hander from Cactus Shadows High School.
Jacobson, whose fastball was timed at 94 mph his junior year in high school, has a scholarship to Vanderbilt, and the D-Backs are unlikely to begin serious negotiations until late August.
Troy Glaus, back in the starting lineup Saturday, said he appreciated manager Bob Melvin’s concern for his health after Melvin initiated an exam by orthopedist Dr. Michael Lee on Friday. "My job is to go out and play," said Glaus, who will not ask for a day off. "Everybody else’s is to tell me no."
