López also homered from both sides of the plate in the same game, making them the first teammates to do so on an Opening Day. Clark slumped badly thereafter, however, as in his next 18 at-bats he only managed to eke out a single. As of May 6 he was batting .179, and had struck out in more than half his at bats. That day Clark was placed on the 15-day disabled list for a lingering wrist ligament injury, and Josh Whitesell, who was hitting .356 for the Reno Aces with a .477 on-base percentage, was called up to the Diamondbacks to take his place. Clark suffered the injury during spring training, and re-aggravated it in late April, leaving him unable to swing comfortably from the left side. It was anticipated that the injury could require more than 15 days to heal. On June 19 Clark came off the disabled list and returned to Arizona (after a rehab assignment at Reno in which he batted .160, and during which he turned 37), and Whitesell was optioned back to Reno (after batting .300 with a .447 on-base percentage in his second stint with the team). In his first game back with the team, Clark went 0–3 with 2 strikeouts to bring his batting average down to .161, with strikeouts in 55% of his at bats for the season. Clark struggled on defense as well, as on June 21 in his second game back he dropped a throw to him at first base with two outs in the ninth, allowing the winning run to score for Seattle. The play left players and managers on both sides stunned and speechless. "It's a miserable ending to a rough road trip", manager A. J. Hinch said. His resulting .973 fielding percentage was last among major league first basemen who had played 60 or more innings. On July 12, 2009, the Diamondbacks released Clark, who was hitting .182 with four home runs and 11 RBIs. They replaced him with Whitesell. Clark said he would continue to work out the next few weeks in the event an opportunity might arise with another team, and that if he didn't land with another team he'd consider broadcasting and coaching, perhaps with the Diamondbacks. Diamondbacks General Manager Josh Byrnes expressed an interest in keeping him with the organization, and Clark said he "would welcome the opportunity." Post-Season Clark played in
