James Shields returns from DL; Miguel Gonzalez goes on DL

The White Sox had an overall good week -- they went 5-2 against two teams from the AL East, taking three of four at home against the Baltimore Orioles and winning two of three on the road against the Toronto Blue Jays.

However, the Sox (31-37) can't seem to shake their season-long problem of pitching injuries. Right-hander James Shields came off the disabled list to make his first start since April 16 on Sunday, but he was merely taking the spot of Miguel Gonzalez, who went on the 10-day disabled list with shoulder inflammation.

Now we know the reason Gonzalez has been so terrible lately. The right-hander has a 10.34 ERA in three June starts, and longer term, he's 1-8 with a 7.32 ERA over his past nine games. His season ERA is 5.49, well above his career norm of 3.97.

As for Shields, he was mediocre in receiving a no-decision in Sunday's 7-3 loss to the Blue Jays. And, honestly, mediocrity is all we expect from the 35-year-old declining veteran. He went 5.2 innings, allowing three earned runs on seven hits with three strikeouts and one walk.

Shields was one out away from getting through six innings with a 3-1 lead, but he couldn't close the deal. He easily retired the first two batters of the inning, but Troy Tulowitzki reached on a scratch infield single that hit the third-base bag. Shields then hung a slider to Russell Martin, who hit a game-tying two-run homer that hit the top of the wall and bounced over in right-center field.

That was Shields' final pitch of the day, and the Sox bullpen -- which has been solid most of the year -- was not solid on this day. Anthony Swarzak (3-2) gave up a single and a triple that allowed the Jays to take a 4-3 lead into the seventh inning.

Swarzak, Dan Jennings and Michael Ynoa combined to give up three runs in the bottom of the seventh as the Jays broke it open and salvaged the finale of the series.

Jennings was brought in to force switch-hitter Kendrys Morales to turn around and hit from the right side, and boy, did that move fail. Morales hit a two-run blast that hasn't landed yet. I've said it before this year, and I'll make the point again: Jennings is overused, having appeared in 32 of the Sox's 68 games. As we go along, his performance gets worse and worse.

The problem is that Jennings is the only left-hander in the bullpen, so he gets summoned to pitch to left-handed hitters on a frequent basis. Injuries have forced David Holmberg into the starting rotation, even though he is more suited to be the second lefty reliever.

Perhaps Holmberg could have kept Morales in the yard Sunday, but alas, he needs to stay in the rotation for now, with Gonzalez headed to the disabled list.
