Burres rejoined the club on Sunday after Chris Jakubauskas was placed on the 15-day disabled list with a head contusion and concussion. Burres actually pitched against Houston in relief on Sunday, allowing two earned runs on three hits and three walks in 1 2/3 innings.
This will be the southpaw's second spot start for Pittsburgh this month. He was called up from Triple-A Indianapolis to make an April 12 start in San Francisco. That outing lasted four innings, and Burres picked up the loss after giving up six runs and eight hits.
There is a chance that the Bucs may need Burres to start one more time after Thursday in order to bridge the gap to Ross Ohlendorf's return from the DL. Whether it's Burres who makes the fill-in start or someone else could largely hinge on how Burres fares in what will be his first career appearance against the Dodgers.
