James Shields back to White Sox after two-month DL stint

Chicago White Sox pitcher James Shieldswas activated from the disabled list and started Sunday's game against the Toronto Blue Jays.

He gave up seven hits and three earned runs, including a two-run home run from Russell Martin that ended his outing, in 5 2/3 innings in Chicago's 7-3 loss.

Shields, 35, has missed the past two months because of a strained right back muscle. The veteran right-hander said Wednesday he is "ready to rock" after three rehab starts for Triple-A Charlotte. He threw 90 pitches, allowing two runs and six hits over five innings, on Tuesday.

Shields was 1-0 with a 1.62 ERA in three starts this season, going into Sunday.

To make room for Shields on the roster, the White Sox placed right-hander Miguel Gonzalez on the 10-day disabled list with inflammation in his throwing shoulder.
