Ronald Belisario's cold streak coincides with his promotion to closer

Remember back on June 12 when the White Sox were only 2.5 games out of the AL Central lead? Some were talking about this team potentially making a surprise run at the division title. Yeah, that was fun while it lasted. Since then, the bottom has fallen out.

The South Siders have now dropped nine out of 11 and have fallen a season-worst seven games (35-42) below .500. They trail the Detroit Tigers by 7.5 games in the division, and they have lost five consecutive games after Monday's 6-4 loss to the Baltimore Orioles.

This latest defeat should not have happened. Ace Chris Sale was in line for the win after allowing just two runs over six innings. He pitched out of a pair of bases-loaded jams to give the Sox a chance at victory. Jose Abreu hit his 22nd home run of the season and drove in three runs, and things were looking good with the Sox up 4-2 in the eighth inning.

Then, the wheels came off. The Orioles got a solo home run from catcher Caleb Joseph off Zach Putnam to tighten the score to 4-3 heading to the ninth. Sox "closer" Ronald Belisario then presided over a spectacular meltdown.

After jumping ahead of Steve Pearce 1-2 in the count, Belisario served up a fat pitch that Pearce hit for a leadoff single. Adam Jones was next hit by a pitch to move the tying run into scoring position and put the winning run on base with nobody out. After Nelson Cruz struck out, Belisario hung a 3-2 slider to Chris Davis, who hit a three-run home run to lift the Orioles to a come-from-behind win.

It's pretty hard to miss the fact that Belisario has been awful since being named closer following an injury to Matt Lindstrom on May 20. Since that date, Belisario has appeared in 13 games, going 7 for 10 in save opportunities. He's allowed 11 earned runs in 11 innings pitched during that stretch. That's easy math: a brutal 9.00 ERA.

Thing is, you can't fault Sox manager Robin Ventura for going to Belisario, because he was the hot hand at the time of Lindstrom's injury. Prior to May 20. Belisario had gone 12 consecutive appearances without surrendering an earned run.

But as soon as he was named closer, Belisario's effectiveness disappeared. Coincidence? I don't believe so. I think Belisario is one of those guys who is just more comfortable pitching the seventh or eighth inning. That's what he's done for most of his career, and he doesn't seem able to handle the responsibility of pitching in the ninth inning.

The closing situation has not gone well for the Sox this year. Lindstrom and Nate Jones, the two top candidates for the job coming into the season, are both on the disabled list. Daniel Webb was mentioned as a potential candidate by pitching coach Don Cooper in the spring, but he has been too wild (25 walks in 35.1 IP) to be trusted in any high-leverage situation - let alone closing.

Belisario is essentially the Sox' fourth option as a closer. It looks like they'll have to find a fifth option, because Belisario is not getting it done.
