A potential season-ending injury is no way for a closer to end a game. But, Chad Qualls did just that on Sunday as he earned his 24th save but took a line drive off of his kneecap on the final play of the game.

Instead of celebrating a three-game sweep, the Diamondbacks tended to closer Chad Qualls, who suffered a dislocated left kneecap on a game-ending play.

Qualls crumpled to the dirt after deflecting a liner by Jason Michaels to shortstop Stephen Drew, who fired to first base for the final out. Qualls immediately motioned to the dugout for help, and trainers and teammates rushed to the mound. After several moments, trainers helped the 6-foot-5-inch, 220-pound Qualls to his feet and off the field.

Arizona manager A.J. Hinch said Qualls had dislocated the kneecap but had no other details about the extent of the injury. Qualls underwent X-rays after the game and did not speak to reporters.

No, I didn't lose a bet to Matt Snyder (although he is running roughshod over our fantasy league right now) and he hasn't stolen my log in information to write favorable posts about the Chicago Cubs. I feel it's just necessary to expound a bit about what's been happening on the north side lately.

The Cubs won their second game in a row and made it back to .500 on Thursday. They did so with a scoring barrage led by Derrek Lee. If Lee's two home runs on Thursday weren't enough foreshadowing for a breakout, imagine that we're only two games into July and Lee already has three homers and nine RBI. He had six homers and 20 RBI in June. Is Lee a 30-home run player again?
